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 landscape index was calculated by using the landscape analysis software. The patch density (PD), edge density (ED), landscape shape index (LSI), degree of aggregation (AI), COHESION, CONTAG, Analysis of Landscape Pattern of Forest Amunshan Nature Reserve in Honghe with Landscape Index Such as Sex Index and SHEI Uniform Index. The results showed that the broad-leaved forest landscape, pine forest landscape and shrub forest landscape were the main landscapes in the Red Mountains Am Nature Reserve. The fragmentation degree of various landscape patches was low and the landscape heterogeneity was high. The overall landscape diversity was low The plaques were evenly distributed in space.
