摘 要：
对深圳市部分立交绿地植物群落的物种丰富度指数、多样性指数、均匀度指数、群落林冠孔隙度和群落叶面积指数进行了比较分析。结果表明,深圳市立交绿地的植物物种丰富,但分布不均匀,多样性不够高;平均叶面积指数为3.05,属中等水平,但不同的立交绿地由于物种组成及结构的不同,其叶面积指数值有差异;平均林冠孔隙度为14.47,在保护较好的立交绿地具有较丰富的非林冠层乔木种类的幼苗。

摘 要：
The species abundance,diversity,evenness,canopy openness,and leaf area index(LAI) of overpass green lands in Shenzhen City were compared and analysed.The results showed that the plant species applied in the overpass green lands in Shenzhen City were rich,but the distribution wasn't even and the diversity was not high.The mean canopy openness was 14.47 and the mean leaf area index was 3.05,which fell in middle level of forest stand.The leaf area index of different plots varied among the communities with different species composition. A more extensive non-forest canopy tree species seedlings grew on the well protected plots.It was indicated that the overpass green-lands could enhance the development of floristic and faunal diversity.
