摘要
运用平坝县森林资源分布图,通过透明网格纸人工统计有关数据,分别计算景观要素优势度、景观斑块密度、景观要素斑块密度和森林景观粒级结构,由此对平坝县的森林景观异质性进行了静态分析。研究表明,平坝县森林景观受环境因子、植被自然演替和人类活动的共同控制,总体异质程度较高。控制因子中,人类活动影响最大。
Based on the forest resource dstribution map of Pingba County, the artificial statistic data was obtained by the transparent grid paper, and landscape element dominance, landscape patch density, landscape element patch density and structure of forest landscape granularity were calculated. Then the data were used to analyze the static forest landscape heterogeneity. The results show that the Pingba forest landscape is controlled by the combination of environmental heterogeneity, natural vegetation succession and human＇ s activities, and the whole landscape heterogeneity changed significantly. Among the effective factors, human＇ s activity is the most.
