- 摘要:
- 对玉溪市生境敏感性和土壤侵蚀敏感性及其生态服务功能进行了分析和评价，以期为更好地保护玉溪生物多样性提供决策依据和参考。结果表明：玉溪市生境极为敏感的区域面积为65 061.78 hm2，占全市国土面积的4.34%，主要是三湖的水体和元江河谷南部的部分沟谷地区；玉溪市植物物种多样性在云南植物多样性中占重要地位，要保护好玉溪市的物种多样性，首先要保护好多样的自然生态系统。
- Abstract:
- The ultimate goal of ecological sensitivity analysis，ecological analysis of the regional environmental，scientific planning，protection of sensitive areas of good study area within the rational development of the weak sensitivity of the area.Yuxi City，the sensitivity of habitats and soil erosion sensitivity analysis to evaluate the ecological service functions，provided a basis for decision making and reference for better protection of Yuxi biodiversity.The results showed that the the Yuxi City habitat extremely sensitive area of 65 061.78 hm2，accounting for 4.34% of the land area of the city，mainly the three lakes of water and Yuanjiang River Valley in southern part of the valley region；plant species diversity in Yuxi City，Yunnan Province of plant diversity had an important role to protect the species diversity of Yuxi City，the first to protect the good and diverse natural ecosystems.
