摘要
运用景观分析软件计算景观指数,采用斑块密度(PD)、边缘密度(ED)、景观形状指数(LSI)、聚集度(AI)、景观联通指数(COHESION)、蔓延度(CONTAG)、SHDI多样性指数和SHEI均匀指数等景观指数分析红河阿姆山自然保护区森林景观格局。结果表明红河阿姆山自然保护区以阔叶林景观、松林景观和灌木林景观为主要景观;各类景观斑块破碎化程度较低,景观异质性较高;景观总体多样性水平较低,各斑块在空间上呈均匀分布。
The forest landscape pattern in Amushan Nature Reserve was analyzed with landscape indices from the landscape structure quantitative software. In this study Patch Density, Edge Density, Landscape Shape Index, Contagion and Shannon＇s Evenness Index were calculated. The results show that broad-leaved, pine and bush were main landscape styles in the reserve. The landscape fragmentation and patch separation degree are fairly lower; the landscape heterogeneity is high. However, the diversity of landscape was lower, each patch was homogeneous in distributing.
