  • 摘要：Faced with the conflict between the environmental protection and timber production, the concept of new forestry and the effect of new forestry objectives on existing harvesting techniques and equipment have been introduced. Adaptive management-a help tool for developing new harvesting techniques and equipment has been proposed. An adaptive approach for developing a forest harvesting for new forestry should be composed of careful planing, considerable hypotheses, detailed testing and evaluating as well as correct and fast feedback. New forestry practices are by no means easy because the complexity of the problem and almost every thing is new. We will see more successful new harvesting techniques and equipment being developing by adaptive approach for new forestry in the future.
  • 摘要：A brief overview of the system of forest inventory in China and its problems existed is given. Forest planning requires information about the current state of the forest resource. However, generally speaking, the information collected in a periodic inventory may become obsolete already after the first thinning following. Therefore,in order to solve the problem, theory skeleton of thinning inventory technique and its approach in forest inventory,is presented in this paper, with an emphasis on the research and study developing currently thinning inventory.
  • 摘要：对北海道北部北海道大学雨龙试验林内的森林流域,不同景观地段的森林冠层凋落物及其养分归还量进行了为期2年的研究。湿地带分布着红皮云杉纯林,河岸带是以毛赤杨和柳树为优势树种的落叶阔叶林,而高地则分布着以白桦、大叶栎和萨哈林冷杉为优势树种的落叶阔叶与常绿针叶树混交林。湿地带、河岸带及高地森林的年平均凋落物量分别为1444、5122和4123 kg·hm-2,凋落物的高峰期出现在9-10月份,落叶量占年凋落物总量的73.4%-87.6%。除了红皮云杉和毛赤杨落叶的氮浓度无显著性季节变化外,其它优势树种落叶的养分浓度具有相似的季节变化规律。所分析的各养分元素归还量都是河岸带林分最高,而湿地带最低;各林分凋落物的不同养分归还量按其高低排序都表现出:N(11-129kg·(hm-2·a))>Ca(9-69)>K (5-20)>Mg(3-15)>P (0.4-4.7)。可见,不同景观地段的森林凋落物量及其养分归还量存在显著差异。不同景观地段的土壤化学性质有明显不同,河岸带土壤的低碳氮比可能是高质量落叶(主要是固氮树种毛赤杨)所致。
  • 摘要：通过搜集和观测印度拉贾斯坦邦高温干旱区纯林和间伐林分内树高和直径数据,完善和比较了4种广义直径-高度关系公式。实验数据包括1540个胸径和树高观测值,采自年龄结构和密度均有差异的蓄积林的样地。通过非线性最小二乘回归方程和不同的统计标准测试四个公式的性能。这些公式利用一组独立的直径-高度观测值(854个)验证(拟合阶段具有相同系数值)公式。结果表明,公式4(Hui and Gadow函数)对拟合数据和验证数据的表现最好。
  • 摘要：The growth of ash (Fraxinus mandshurica) in different mixed stands with larch (Larix gmelini), Korean pine (Pinus koraiensis) and spruce (Picea koraiensis) had been investigated. Meanwhile, the relationship between the growth gain of mixed stand and topographic factor, and the growth comparison of ash in pure and mixed stands with different age-stages were presented in this paper. The results show that the effect of ash and larch mixed stand is very significant. The growth gain of ash in mixed stand on east slope is better than that on west. The growth effect is the most significant on east upper slope and on west down slope. The growth of ash can be increased significantly during different age-stages, but of Larch only through its occupying dominant position in above-ground competition.
  • 摘要：在印地安具有亚热带潮湿气候特点的东北地区,本文对几种多种用途的树种进行研究。选择12种多用途树种种植在农林系统中,耳果相思(Acacia auriculiformis),种植间距为2m×2m(2500 个·hm-2),有很大的生长潜力。在 10 年期的短期轮伐中,每年有很高的产量(635 m3·hm-2),平均每年增涨量为 2.54×102 m3·tree-1·a-1,可以满足薪碳材的需要。所以,耳果相思(Acacia auriculiformis)是一种短期轮伐树种,适合种植在潮湿亚热带气候地区。另一方面,16年树龄的桉树(Eucalyptus hybrid)和黄兰(Michelia champaca) 种植间距为3m×3m (1111个·hm-2),分别有较高的生长量(315 m3·hm-2和165 m3·hm-2),平均每年每棵树增长量分别为1.77×10-2 m3和0.92 × 10-2 m3。16年树龄的印度石梓(Gmelina arborea) 木材产量为147 m3·hm-2,每年每树的增长量是 1.47×10-2 m3。其次为 Samania saman(140 m3·hm-2)和柚木(Tectona grandis (79 m3·hm-2)),平均每年每树的增长量分别是 1.40,1.13和0.78×10-2 m3。毒鼠豆属植物(Gliricidia maculate) 和银合欢(Leucaena leucocephala) 可以用作农厂的围栏并提供农作物的肥料。在植物园,种植树木的最初 8 年间,可以种植高地水稻(Oryza sativa–variety, AR-11), 落地花生(Arachis hypogaea–variety, JL-24)和胡麻(Sesamum indicum–variety,B-67)。由于林下郁闭度太大,在耳果相思(Acacia auriculiformis)林下的农作物产量不高,与空旷地的农作物比较产量有所降低。树木种植 8 年后,种植草料作物如,凤梨、姜黄、豇豆,它们的产量在印楝(Azadirachta indica)林下很高。高产量的农作物和园艺植物与具有高产量多种用途树种一起种植构成了有发展前景的农林系统,并改变土壤特性,改善土壤酸度,提高土壤有机质,降低土壤腐蚀度,提高土壤含水量。
  • 摘要：The relationship between the change of forest resources and climatic factor in the "Three-North" region of China were studied in this paper. The predicting equations of climatic factor (dependent variable) with regional independent variable (longitude, latitude and altitude) and stand independent variable (forest coverage rate),were developed by extensively using the linear and nonlinear regression methods. With these models, we can calculate the ecological benefit of Shelter-belt forest.

  • 摘要：The Daxing’an Mountains and Hulunber Grassland are located in the nor-theastern border area of China. This region covers a large area of rich biodiversity. The natural environment here is well protected because of Iow pressure of human activity. There are 5 species of cranes here. They are Red-crowned crane (Grus japonensis), White-napped crane (Grus vipio), Siberian White crane (Grus leucogeranus), Grey crane (Grus lifordi) and Demoiselle crane (Anthropoides Virgo). Red-crowned crane is a breeding species that is widely distributed in this area. The main breeding population of this species is in Heilongjiang Province. They migrate to the south of China in winter. White-napped crane, Grey crane, Demoiselle crane are also summer birds. It remains unknown if Siberian White crane breeds here. Since the population of Red-crowned crane, White-napped crane, Siberian White crane in China are at the edge of endangering, so they are listed in the namelist of national protected species. But Grey crane, Demoiselle crane have a larger population. and are widely distributed.
  • 摘要：本研究分析了亚热带常绿阔叶林两个重要林型-针叶林与阔叶林在凋落物降解-温度关系的差异。研究表明,低温处理下阔叶林内微生物降解者所引起的凋落叶失重量高于针叶林,然而高温处理下两种林型内叶片失重量并未表现出显著差异。温度升高未引起针叶林内叶片失重量的变化,却显著降低了阔叶林内叶片失重量。低温处理下阔叶林内微生物功能群产生的木质素失重较针叶林高,但高温处理并未引起两林型内木质素失重的差异。温度升高提高两林型内木质素的降解。另外,两种温度处理下,阔叶林内微生物降解者功能群引起的碳水化合物降解高于针叶林。温度升高减少了阔叶林内碳水化合物降解,但并未改变针叶林内碳水化合物降解水平。尽管多数微生物降解酶活性与凋落物失重之间存在较强的相关性,但大多数酶对林型和温度的反应与叶片降解对林型和温度的反应不一致。原因在于叶片与其有机组分的降解是由多种降解酶共同作用的结果。总体上来说,针叶林与阔叶林表现出不同的温度-降解关系。
  • 摘要：调查了施加氮肥(15NH4和15NO3)处理后在两个连续生长季内欧洲水青冈(Fagus sylvatica L.)幼苗地上部分和地下部分的生物量和营养元素分配。盆栽欧洲水青冈幼苗培养于温室大棚内,培养土样取自相邻的三种林分:欧洲水青冈,挪威赤松,欧洲水青冈-赤松混交林。结果表明,氮肥(15N)处理对欧洲水青冈营养元素分配没有显著影响,施加氮素形式决定自身流入植物库的情况。欧洲水青獭收氮素主要以硝态氮的形式,因此,尽管植物体内保存的硝态氮和氨态氮并没有统计差异,但是叶片中硝态氮明显减少。施加硝态氮对欧洲水青冈氮素恢复的影响要大于施加氨态氮。与欧洲水青冈茎、粗根相比,优质根系对氮素(15N)固定是一个缓慢过程。表8图1参40。
  • 摘要：采用样地调查法,对日本冲绳岛北部的亚热带常绿阔叶林的林分结构,树种组成以及土壤特性等进行了调查分析。结果表明,该亚热带林具有林冠低矮、小径木多等特点。林分的平均林冠高度仅10m,平均立木密度达5400株·hm2(≥3.0cmDBH),其中胸径小于10cm的立木占64%。林分胸高断面积为54.4m2·hm-2。30个调查样地共出现树种数(≥3.0cmDBH)达80种,分属31个科。根据树种的重要值,Castanopsis sieboldii和Schima wallichii分别为优势树种和亚优势树种。树种多样性指数(H’)平均达3.63,均衡度指数(J’)为0.71,丰富度指数(S’)为4.72。这些多样性指数都随着优势树种重要值的增加而显著降低。土壤养分测定结果表明,该森林的土壤肥力低,异质性大,并可能存在Al毒害。由相关分析知,林分密度和优势树高均与土壤pH值呈显著正相关关系;多样性指数则与土壤交换性K+,Ca2+以及Ca2+/Al3+比呈显著的正相关,而与土壤有机碳,全氮和磷呈显著的负相关。这些结果说明土壤性质是影响冲绳亚热带常绿阔叶林林分结构和树种组成多样性的重要因素。图3表4参38。
  • 摘要：In order to improve environment and relieve poverty, China has launched a series of major ecological engineering programs since the 1980 s. These include the Natural Forest Conservation Program, the Sloping Cropland Conversion Program, the Desertification Combating Program, and the Protection Forest System Construction Program. There is a growing need to quantify the contributions of these programs to regional carbon stocks.However, the lack of widely accepted, robust methods is one of the key obstacles to quantification. The objective of this study was to review existing methods for quantifying regional carbon stocks and then recommend suitable ones for the Chinese ecological engineering programs. We expect that the recommended methods can be applied to elsewhere in the world where there are similar characteristics and objectives.
  • 摘要：红树林内生真菌1893是从中国南海秋茄(Kandelia candel)上分离的一株内生真菌,在液体发酵条件下能够产生包括1893A和1893B在内的多种新物质。为了正确的鉴定该菌株并为进一步的工业应用做准备,本文结合形态学和分子学两方面对它进行了鉴定,首先,在纯培养条件下,将它和具有以下形态特征的相似菌株进行比较:产生受精丝或像受精丝一样的菌丝,这些菌丝又和像雄器一样的菌丝发生明显的融合现象;环状产囊体与大量菌丝缠绕形成菌核前体。进一步通过该菌株在寄主秋茄和非寄主芒果叶子上的培养性状与其它相似真菌比较,结果将该菌株归于拟茎点霉属(Phomopsis)。其次,在ITS序列水平上,将它和具有形态学或生态学相似性的拟茎点霉进行系统发育分析。最后,综合形态学和分子学,红树林内生真菌1893被定为Diaporthe phaseolorum var.sojae,本文是首次报道Diaporthe phaseolorum var.sojae做为内生真菌寄生于秋茄。图5参43。
  • 摘要：Knowledge about agricultural ecosystems, as well as about ecological and social interactions that occur in an agricultural context, is essential to promote a balanced environment for production. Incorporating the forest landscape into farming systems has promoted the development of integrated production systems such as agroforestry. However, many aspects of the relationship between farming and the forest landscape have changed since the modernization of agriculture introduced by the Green Revolution. The objectives of this review are:(1) to contribute to the understanding of the changes in cultivation strategies and in the dynamics of agricultural systems,particularly in the context of farming in Santa Catarina State, Brazil;(2) to contribute to the understanding of agroforestry systems as a strategy to reintroduce the element of forestry into agricultural production systems; and(3) to compile a list of forest plant species that could be used in agroforestry. The approach adopted in this manuscript seeks to highlight the potential of agroforestry systems to conserve natural resources and thereby to support agricultural development by connecting environmental conservation with income for farmers.
  • 摘要：Peroxidase plays important roles in many stress-related interactions and catalyzes important reactions in various physiological processes. Since peroxidase played critical roles in the evolution of almond(Prunus dulcis Miller(D.A Webb) syn P. amygdalus Batsch), peroxidase-gene-based analyses may increase the understanding of evolution of this species. Peroxidase gene polymorphism(POGP) markers were used to determine genetic diversity and relationships among 69 Turkish genotypes/cultivars and 27 foreign almond cultivars by using unweighted pair group method with arithmetic mean(UPGMA) analysis. This study is the first evaluation of the use of POGP markers for diversity analysis in almond.Totally, 83 fragments were obtained from eight peroxidase primer pairs, and polymorphism was identified as 94 %.Similarity level among the genotypes ranged between 0.63 and 0.93, and all materials were distinguished. In general,Turkish and foreign genotypes were mixed in clusters since they share a common genetic background and gene migration among the sites. Clusters were not based on geographic regions except for some minor groupings. This study indicated that peroxidase gene markers can be reliably used to determine genetic relationships in almonds.
  • 摘要：We examined the local community incentive programs to improve traditional forest management in three forested villages in Baneh city,Kurdistan province in the northern Zagros forests of western Iran.Zagros forests cover 6.07 million ha and support rich plant and animal diversity.Changes in local community social and economic systems and the inefficiency of traditional forest management led to a critical situation in the stability of forest regeneration in recent decades.Due to a shortage of productive and arable lands and resulting unemployment and poverty,people overexploited the Zagros forests.Outside intervention in traditional forest management creates conflicts between local peoples and forest management organizations.To achieve sustainable forest management,including forest resources conservation and improvement of natural resource based livelihoods of communities,it is desirable to implement Forestry Incentive Programs(FIP)based on the important functions of forests.Detailed information on the socio-economics of communities,the effect of forests on local livelihoods,and lists of products extracted from the forest were obtained from a survey of local communities though questionnaire,interview and We studied 276 households in three villages and completed 76questionnaires by householders in the quantitative analysis.Sampling was performed by simple random sampling(SRS).The needs of rural communities,such as livestock husbandry,mainly arise from the characteristics and environmental features of villages.We identified the driving forces,pressures,status,impacts and responses(DPSIR)to design incentive programs,by DPSIR analysis and interaction analysis.Evaluation of local community benefits from forests showed that in order to improve forest management,319 dollars per year would be needed by each family as an incentive in 2010 to prevent lopping and firewood collecting,the main causes of forest degradation.
  • 摘要：Seeds and seedlings of five broad-leaved species were separately exposed to simulated acid rain at pH values of 2.0, 3.5, 5.0, and 6.0, or to distilled water (the control). The results showed that seed germination was remarkably inhibited by pH 2.0 treatment for three species. Significant foliar damage, decline in chlorophyll contents, and retardation of the seedlings growth of all the species, were observed at pH 2.0 treatment. The pH 2.0treatment seemed to be a threshold level for inhibition of seed germination and seedling growth for all the treated species, while seedling was stimulated at pH value between 3.5 and 5.0.
  • 摘要：In this paper, the conceptions and developments of ecosystem and ecosystem ecology were reviewed and summarized. Then, the conception, connotation, objective, and development of ecosystem management were expounded. Based on these discussions, forest ecosystem management was discussed. The viewpoint was that the former unreasonable forest resources management should be changed, and forest ecosystem management was a suitable way to sustainable development of forestry. The chief research contents were also pointed out in this paper.
  • 摘要：Data analysis was made for 54 stands of Chinese pine forests for soil and water conservation and timber. The regression equations were drawn up on forest density and different rafter timber and bush coverage.Based on those equations, the number of rafter timber trees, storage, number of non-raffer timber trees, stand volume and the output value were calculated for six different forest densities ranged from 1250 to 6600 trees/hm2.According to the economic and ecological criteria, the optimum density for Chinese pine forests was determined as 1 650 trees/hm2.
  • 摘要：利用高效液相色谱法(HPLC)测定匙羹藤(Gymnema sylvestre)不同器官的匙羹藤酸含量。结果表明:不同器官的匙羹藤酸含量明显不同,在顶芽、花、节点、叶、节间、根和种子的匙羹藤酸含量分别为,54.29, 31.66, 28.82, 27.67, 25.39, 20.56和1.31 mg·g-1 DW。在幼叶中,匙羹藤酸(35.39 mg·-1DW)含量最高,比老叶的匙羹藤酸(23.07 mg·g-1DW)含量高1.52倍。幼年,中年和老年节间的匙羹藤酸含量分别为26.47, 25.77和23.94 mg·g-1DW,均低于叶的匙羹藤酸含量,而幼嫩,中部节和老节点的匙羹藤酸含量分别为27.96, 28.81和29.66 mg·g-1DW,均高于叶的匙羹藤酸含量。因为过度开采引起了这些植物在自然界的损耗,本研究为匙羹藤资源的发展和利用提供了科学依据。
  • 摘要：Isoperoxidases of fourteen species of poplars in Heilongjiang Province were analyzed by polyacrylamidegel disc-electrophoresis. The major zymogram of petioles of poplars was consisted of twelve kinds of isoenzymes, in which 35% zymogram was just the same and represented the specialized zymograms of poplars. The resuits of the experiments showed that the closer the affinity relationships of the species were, the greater the similar values between the zymograms were. There were very great similar values among natural hybrid species.But in sect. Tacamahaca Spach, the similar values between Populus koreana Rehder and P nakaii Skv were obviously smaller .Isoenzyme analysis provided new information for plant classification on the molecular level.
