长春城市绿地植物群落生态脆弱度分析

Ecological Frangibility Degree Analysis on Plant Communities in Changchun City

以北方寒地城市长春市为例,提出城市绿地植物群落生态脆弱度计算方法,对长春城市各类绿地进行了详细的植物群落生态脆弱度分析,分别论述了景观效果、绿地结构、绿地养护及人工干扰与生态脆弱度的关系,指出建立科学合理的复合群落绿地是从根本上降低城市绿地生态脆弱度的唯一出路。

Taking Changchun of the cold city in the north as an example,the method of calculating the degree of ecological frangibility was pointed out.The degree of ecological frangibility in all kinds of greenery plots of Changchun was analysed.The relationships of the degree of ecological frangibility were discussed with landscape effect,greenery plot strueture,greenery plot maintenance,and interference of mankind.It was expounded that constructing compound plant communities scientifically was the only way out to reduce the degree of ecological frangibility of greenery plots.
