滇西北地区自然村对滇金丝猴生境质量的影响

在社会经济发展与生态环境发展逐渐失调的背景下，滇金丝猴作为中国特有的珍稀濒危物种，其生境质量的研究是平衡经济发展与物种保护的重要基础。选取滇西北地区2572个自然村的社会经济数据和344个样地运用GIS空间分析法的主成分分析和InVEST模型，研究滇西北地自然村发展对滇金丝猴分布区生境质量的影响，结果如下：(1)研究区南部自然村发展优于北部；(2)研究区北部的生境质量比南部高，北部自然村对滇金丝猴生境质量的影响比南部的自然村小；北部的生境稀缺性比南部高，生态稳定性差，需要制定优先保护策略；(3)猴群分布区内存留12个自然村，自然村发展对第3、6和14猴群(C3、C6和C14)的生境质量影响大，生境质量比较低；猴群C1、C12和C13分布区内的生境稀缺性较高，生境脆弱，需要优先加强规划；划定滇金丝猴优质生境、中等生境和低质生境区域，占比分别为26.85%、20.44%和52.71%。

Impact of the villages on habitat quality of Yunnan snub-nosed monkey in northwest Yunnan

Improvement of villages'' economies in and around the Yunnan snub-nosed monkey''s habitats continues to come at the cost of decreasing ecological quality of the habitats. These areas are rich in natural resources and their biodiversity is among the richest in China. This paper uses the Principal component analysis and InVEST model of GIS spatial analysis to study the impact of villages'' economic growth on the habitat quality of the Yunnan Snub-nosed monkey. The analysis included 2,575 villages and 344 sample plots in the monkey''s northwest Yunnan habitat. There were 12 groups of monkeys in this study. The results are as follows:(1) The economic development of villages in the south was better than that in the north. (2) The habitat quality in the northern region was higher than that in the southern part. The impact of villages in the north of the Yunnan snub-nosed monkey''s habitat quality was smaller than that in the south of the region. The northern habitat rarity was higher than that in the south, necessitating priority protection strategies due to the ecological stability weakening. (3) There were 12 villages in the monkey habitats. Three groups (Groups 3, 6, and 12) had low habitat quality, which affected the development of the villages. Three other groups (Groups 1, 12, and 13) had scarce (fragile bio-diversity) habitats, which needed to be prioritized for protection and repair. Over half the habitat area (52.71%) was low-quality, about one-quarter (20.44%) was medium quality, only about one-quarter (26.85%) was high quality.
