以西北黑河流域为研究对象,在野外调查、资料收集的基础上,借助3S 技术编制黑河流域现状植被图(1:100000).结果表明,黑河流域植被图共包含9个植被型组、22个植被型、74个群系(亚群系);增加了1:1000000植被图中因分布面积过小而忽略的植被型和群系,新增2个植被型,9个群系和3种无植被地段类型,其中2个植被型为温带落叶阔叶灌丛和亚高山常绿针叶灌丛;群系斑块数目从786增加到13151个.调整了各分类单位的边界,细化了各分类单位的分布区域,大大地提高了植被图精度,较好地反映了区域中等分辨率植被分布,对黑河流域生态-水文-经济综合模型构建和管理决策具有很大参考价值.制图方法可用于因环境限制无法进行充分野外调查的干旱区及高山区域植被制图.%Taking Heihe River Basin as an example,a status vegetation map in Heihe River Basin(1:100 000)with the aids of 3S technology is presented based on the documentary data and filed sampling data. The results show that the vegetation map in Heihe River Basin was divided in to 9 groups of vegetation type including 22 vegetation types and 74 formations(subformations);2 vegetation groups,9 formations and 3 land without vegetation were included in the vegetation map with 1:100 000,due to the small area excluded in vegetation map with 1:1 000 000,and 2 vegetation types including temperate broadleaf deciduous scrub and subalpine needleleaf evergreen scrub;the spots of map increased from 786 to 13151, the boundary of each classification unit was reasonably adjusted,the distribution area of vegetation were appropriately decided,and the accuracy of map was highly increased.The vegetation map of Heihe River Basin well reflected the vegetation distribution of medium resolution,this vegetation map will provide a solid scientific database for the building of an integrated ecological-hydrological-economic model that contributes to comprehensive management and decision-making in the Heihe River Basin.The mapping method was useful for vegetation mapping in extreme environments in arid land and alpine regions that comprehensive field investigation was impossible.
