摘要
宾川上沧海湿地为云南省第三批省级重要湿地,区域地位较为重要。为及时掌握上沧海湿地生态环境健康状况,采用LDI方法评价了该湿地的健康等级。结果表明:研究区域土地利用类型以林地为主(43.27%),其次为耕地(26.19%),再次为园地(14.13%),建设用地分布于湿地四周,占研究区域面积的5.44%;湿地区域枯水期土地利用类型以草地为主(68.16%),丰水期以水体为主(79.10%);建设用地、耕地及园地等干扰较强的土地利用类型在研究区域的空间分布较为均匀,对湿地表现出较强的干扰。整体上研究区域及湿地的生态环境健康等级处于"一般"水平。
Shangcanghai wetland in Binchuan County is one of the third batch of important provincial wetlands in Yunnan Province.It is located in the biodiversity hot spot area of Western Yunnan,and its regional status is relatively important.In order to grasp the ecological environment health status of Shangcanghai wetland in time and provide guidance for regional ecological environment protection,the health level of the wetland was evaluated by LDI method.Result shows that:forest land is the main land use type in the study area(43.27%),followed by cultivated land(26.19%),garden land(14.13%),construction land is distributed around the wetland,accounting for 5.44%of the study area;grassland is the main land use type in the dry season(68.16%),and water is the main land use type in the wet season(79.10%);the spatial distribution of land use types with strong interference,such as construction land,cultivated land and garden land,is relatively uniform in the study area,and they have strong interference on wetlands;on the whole,the ecological environment health level of the study area and wetland is at the“general”level.In view of the existing problems of Shangcanghai wetland,the relevant protection suggestions were put forward.
