深圳市盐田区植被格局分析

Vegetation Pattern and Protection of Landscape Diversity in Yantian District,Shenzhen City.

运用景观生态学的方法 ,选取斑块形状指数、斑块形状破碎化指数、分维数、景观多样性指数、均匀度、相对丰富度、优势度等指标 ,对深圳盐田区的植被格局进行分析。结果显示 :在城乡发展过程中 ,盐田区植被景观保存较好 ,类型丰富 ;植被景观总体上呈现出符合其生境特征的规则分布 ;群落景观异质性较高 ,拥有南亚热带的沟谷雨林、山地常绿阔叶林、红树林等特色植被景观 ;沟谷雨林和季风常绿林是本区较脆弱的生态系统 。

By applying landscape ecological approaches,the vegetation spatial pattern of Yantian District,Shenzhen City was analyzed.For the research patch shape index,fragmental index of patch shape,fractal dimension,landscape diversity index,evenness,relative richness and landscape dominance index were taken as the major indexes.Results show that the vegetation landscape in Yantian District has been well preserved in the process of urbanization,and diversified in type;its spatial pattern appears regular and consistent with the characteristics of its habitat;the district is high in community landscape heterogeneity,and features south subtropical valley rainforests,mountain evergreen broadleaf forests and mangroves;the valley rainforests and monsoon evergreen forests in this district are ecosystems relatively fragile,which deserve protection and development.
