摘要
通过对黑松林径阶结构和草本植物多样性进行分析,揭示了大连不同立地条件下黑松林的径阶空间的分布特性和草本植物的生物多样性。结果表明:大连岩质海岸地区的黑松林部分立地条件存在着退化趋势,草本植物种类单一,黑松径阶分布曲线不呈正态分布。
Diameter grade of Pinus thunbergii and diversity of herb plant were analyzed.Distribution characteristics of diameter grade for Pinus thunbergii plantation and biodiversity of herb plant under different site conditions of Pinus thunbergii in rocky coast of Dalian were revealed.Result shows that there is a degradation trend in Pinus thunbergii in Dalian rocky coast;species of herb plant is single;diameter distribution curve in Pinusthunbergiiis not normally distributed.
