Abstract

By using the quantitative index of 'probability of connectivity', this paper analyzed the effects of road network on the landscape pattern, ecological process, and landscape function in the typical areas of Yunnan Province. Road network accelerated landscape fragmentation, and changed the structure, number, and distribution pattern of ecological process dispersal paths, with the effects increased with increasing dispersal ability. The road network generally reduced the landscape function in maintaining ecological process connectivity by > 10% and the patch function by > 40%, and the effect also increased with increasing dispersal ability.

摘要

通过使用“连通概率”这一定量指标，本文分析了道路网络对云南省典型区域景观格局、生态过程及景观功能的影响。道路网络加速了景观破碎化，改变了生态过程扩散路径的结构、数量及分布格局，且随着扩散能力增强，影响也增大。道路网络总体上使维持生态过程连通性的景观功能降低超过10%，斑块功能降低超过40%，且该影响也随扩散能力增强而增大。
