摘　　要：利用云南省第二次湿地资源调查数据,采用层次分析等方法,对全省重点调查湿地生态状况进行了综合评价。结果表明,云南省重点调查湿地中,生态状况为"好"的湿地占总数的41.18%,占湿地总面积的12.81%;生态状况为"中"的湿地占总数的40.0%,占湿地总面积的61.08%;生态状况为"差"的湿地占总数的18.82%,占湿地总面积的26.11%。全省重点调查湿地生态状况总体偏中下水平。一些对云南省、全国乃至世界具重要意义的湿地虽已纳入保护地体系中,但其生态状况不容乐观,湿地保护仍有待进一步加强。云南省以山区为主的国土资源禀赋,导致其全省湿地面积偏少,其中能够被有效利用的湿地资源更少,而全省社会经济发展高度依赖于十分有限的湿地资源,尤其是处于坝区的湖泊,使这些湿地资源承载了过于沉重的压力,也因此受到不合理利用的严重威胁,形成了目前的湿地生态状况及其分布格局。云南省湿地资源弥足珍贵,保护湿地生态红线意义重大。Based on the data obtained in the Second Wetland Resources Survey, the ecological status of key wetlands in Yunnan province was analyzed by using Analytic Hierarchy Process,and the results shows that the ecological status of 41.18% of key wetlands were＂Good＂,and areas of these wetlands accounting for12.81% of total areas of wetlands;12.81% of wetlands were ranked＂Middle＂,and the areas of which accounting for 61.08% of total wetland area; 18.82% of key wetlands were ranked ＂Poor＂, and the areas of these＂Poor＂wetlands accounting for 26.11% of total wetland area. The ecological status of key wetlands in Yunnan were worrying in general, and the ecological status of some wetlands of national and international significance in Yunnan were unoptimistic and the protection should be strengthened although those significant wetlands have been covered by present protected areas. The total areas of wetlands in Yunnan are less and fragmented,and the areas of usable wetlands are even lesser for particular mountainous land resource endowments of the province. The development of province, however, is highly relied on these wetland resources, especially lakes distributed in rivers basins. And the ecological status and distribution pattern of key wetlands was the result of overuse and pressures exerted on these wetlands. The result reflected that the wetland resource in Yunnan province is precious and it is significant to making＂the Ecological Red Line＂for the wetland resource.
