摘要: 针对云南省因土地利用结构变化,自然环境遭到破坏,导致许多物种极度濒危甚至灭绝、生物多样性遭到严重破坏的问题,本文利用最大熵模型(MaxEnt)对云南9种特色优先保护物种进行了环境适宜性分析。首先以资源环境承载力及国土空间开发适宜性为基础,筛选出具有云南特色的9个优先保护物种,然后对各物种的最优生存环境进行了预测。研究结果表明,云南省9种优先保护物种现存分布区总计0.21万km2。经最大熵模型(MaxEnt)预测可知,最优适生分布区可达5.45万km2,是现存分布区的25倍。

Abstract: In view of land use changes in Yunnan province, natural environment damages, which leads to extremely endangered or even extinction of many species and serious destruction of biodiversity.In this paper, MaxEnt model is used for environmental suitability analysis.Based on the carrying capacity of resources and environment and the suitability of territorial spatial development, we selecte 9 priority protected species with Yunnan characteristics to predict the optimal living environment of each species. The study finds that the extant area of the nine preferentially protected species in Yunnan province total 2100 square kilometers, and MaxEnt model is predicted to reach 54 500 square kilometers, which is 25 times of the extant region.

Key words: diversity of species, habitat environment, ArcGIS, MaxEnt model, forecast
