溧阳地区森林景观的生物多样性评价

摘要

Forest ecosystem diversity of the forest landscape and the species diversity of the main forest ecosystem types was studied.The research site Liyang district is a representative in forest vegetation and in social economy at that highly developed area.Based on this,the evaluation on the dynamic state of bio-diversity of the forest landscape was assessed by calculating index W and index Z.The conclusion shows that the bio-diversity level of the forest landscape in Liyang district comes down during the past twenty years.%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20a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。
