对在江苏省南部和太湖流域具有一定代表性的溧阳地区的森林景观开展了森林生态系统多样性的研究 ,对主要森林生态系统类型分层次进行了植物种多样性的调查分析。基于生态系统和物种两个水平的多样性调查研究 ,尝试以 W和Z两个指标对研究区域森林景观的生物多样性特征进行历史的动态评价 ,结果体现出在近 2 0 a的森林经营过程中 ,溧阳地区森林景观的生物多样性水平有下降的趋势。
The study of forest ecosystem diversity in the forest landscape of Liyang, which is representative in the southern part of Jiangsu Province and the Taihu Lake basin, conducted a survey and analysis of the plant species diversity at different levels in the major forest ecosystem types. Based on the investigation of biodiversity at both the ecosystem and species levels, this paper attempts to conduct a historical dynamic assessment of the biodiversity characteristics of forest landscapes in the study area using W and Z indicators. The results show that during the past 20 years, , The biodiversity of forest landscape in Liyang tends to decline.
