黄浦江河岸带植物资源调查与健康状况评价

         

摘要

河岸带植被是河岸带结构与功能的核心,摸清河岸带植物资源状况是对河岸进行治理、修复和绿化的前提与基础.本研究根据黄浦江流经的行政区,将其江河岸带划分为3段:市区段、近郊段、远郊段,分段调查了河岸带植物资源状况,包括植物种类及群落特征,并结合QBR指数法评价分析了河岸带植被质量健康状况.研究结果显示,黄浦江河岸带植被共计177种,分别隶属于74科129属,市区段植物资源种类最丰富,共120种,隶属于59科97属,占总种数的67.8%;其次是近郊段104种植物,隶属于53科88属,占总种数的58.8%;植物种类最少的是远郊段.黄浦江河岸带植物群落共计158个,可归纳为6大类型:香樟群落、响叶杨群落、落羽杉群落、垂柳群落、女贞群落、池杉群落,以香樟群落数量最多;群落结构分为4种类型:乔、乔-灌、乔-草和乔-灌-草,其中二层结构居多.根据评价打分结果,黄浦江河岸带植被质量总体状况一般,远郊段质量最好,市区段最差.造成植物资源分布和植被质量差异的主要原因是开发利用强度、硬质化程度、绿化水平和人为干扰程度的不同.根据调查情况,本研究系统地反映黄浦江河岸带植物资源现状与特征,从而为其河岸带综合治理、修复改造和绿化建设提供科学依据和参考.%Riparian vegetation is the core of the riparian structure and function,and a thorough investigation of riparian vegetation resources is the premise and foundation of riparian management,repair and greening.According to the borough Huangpu River flows through,the river riparian zone is divided into three reaches:downtown,suburb and outskirts.This study investigates plant species and community characteristics of each reach,and evaluates the health quality of riparian vegetation by QBR index.The results show that there are totally 177 species which belong to 74 families and 129 genera in this zone.Plant species in downtown reach is significantly richer than others,which have a total of 120 species belonging to 59 families and 97 genera.It accounts for 67.8% of the total number of species.Then,the suburb reach has 104 species of plants,belonging to 53 families,and 88 genera,and it accounts for 58.8% of the total.While the plant species in outskirts is the least.There are 158 plant communities,which can be grouped into six major types:Cinnamomum camphora community,Populus adenopoda community,Taxodium distichum community,Salix babylonica community,Ligustrum lucidum community,and Taxodium ascendens community.Among them,the number of Cinnamomum camphora community is the maximum.The structure community is divided into four types:tree,tree-shrub,tree-herb,and tree-shrub-herb.And the two layer structure is the most.The health assessment results show that the overall condition of riparian vegetation of Huangpu River is generally.The outskirts reach is the best,while the downtown reach is the worst.The difference of the distribution of plant resources and vegetation health quality are caused by the impact of development and utilization intensity,hardening degree,greening level,and human disturbance.According to the survey,this paper reflects the status and characteristics of the Huangpu River riparian vegetation resources systematically,and provides a scientific basis and reference for riparian comprehensive improvement,renovation,and greening construction.
