东莞市大屏嶂森林公园微地形对植被多样性的影响
Influence of Micro Topography on Vegetation Diversity in Dapingzhang Forest Park of Dongguan City
摘要
Abstract
[Objective]To study the relationship between microtopography and vegetation diversity.[Method]A forest monitoring plot of 1 hm2 was established in a secondary southern subtropical evergreen broadleaved forest in Dapingzhang Forest Park and conducted a tree census.The correlations between microtopographic conditions and forest plant diversity were tested.[ Result]①It recorded 2209 individuals of 45 species from 38 genera and 24 families in the 1 hm2 forest plot, with a density of 0.2209 individuals/m2 .The forest plot was dominated by Cyclobalanop-sismyrsi-naefolia.The Shannon-Wiener index and the evenness of the forest plot were 1.29 and 0.56, respectively.②Plant diversity index was highest on the abrupt slope(1.46) and lowest on the steep slope(1.19).③Plant diversity index on different aspects ranked form big to small as follows:north aspect(1.95), west aspect(1.47), east aspect(1.31), south aspect(0.95).④Plant diversity index on the upslope positions (1.43) was similar with that on the downslope positions(1.40), and that on the midslope positions was lowest(1.29).[Conclusion]The results can serve as references to further exploration of the underlying mechanisms of species diversity maintenance.关键词
