摘要
依据森林资源规划设计调查成果数据,参考全国森林资源连续清查的评价方法,以有林地小班为基本评价单元,选取8项特征因子,构建了森林生态功能评价指标体系,对北京市京西林场管理处的森林生态功能进行了评价。结果表明:①北京市京西林场管理处森林生态功能指数为0.48,森林生态功能总体处于“中”等水平;②北京市京西林场管理处的森林,生态功能为“中”等水平的森林面积3153.52 hm^(2),占有林地面积的91.21%;生态功能为“差”等水平的森林面积304.01 hm^(2),占有林地面积的8.79%。
According to the results of forest resource planning and design survey in Beijing Jingxi Forestry Administration Office,national continuous forest inventory assessment methods was used to evaluate the ecological function of Forestry Administration Office.Taking the stand of arbor forest as the research object,8 feature variables was selected and a forest ecological function system was established,so the forest ecological function of Beijing Jingxi Forestry Administration Office was evaluated.The result showed that:①The comprehensive evaluation index of forest function in Beijing Jingxi Forestry Administration Office was 0.48,and the grade of the forest ecological function was"medium".②Beijing Jingxi Forestry Administration Office is dominated by arbor stand with forest ecological function grade of"medium",with an area of 3153.52 hm^(2),accounting for 91.21%of total evaluation area;the area of"poor"is 304.01 hm^(2),accounting for 8.79%.
