【摘要】：以云南省9个高原湖泊为研究对象,采用高原湖泊水质与湖泊流域土地利用类型变化的面积数据构建了各土地利用类型对高原湖泊水质影响的关系模型,同时运用各高原湖泊流域土地利用强度与水质动态变化的时间序列数据构建了库兹涅兹曲线。研究结果表明,耕地、园地、湿地面积与湖泊含磷量存在一定负相关关系,林地、牧草地、建设用地面积与湖泊含磷量存在一定的正相关关系,牧草地、耕地、园地、湿地面积与湖泊含氮量存在一定负相关关系,建设用地面积与湖泊含氮量存在一定的正相关关系,园地和耕地面积与污染综合指数存在负相关关系,建设用地面积与污染综合指数存在负相关关系。滇池、泸沽湖处于流域协调区间,阳宗海、抚仙湖、星云湖、程海处于流域冲突区间,洱海、异龙湖处于冲突区间向协调区间转型过程之中。
[Abstract]:Taking nine plateau lakes in Yunnan Province as the research object, the relationship model of the effects of different land use types on the water quality of plateau lakes was established by using the area data of the water quality of plateau lakes and the changes of land use types in lake basins. At the same time, the Kuznets curve was constructed by using the time series data of land use intensity and water quality dynamic change in each plateau and lake basin. The results show that there is a negative correlation between the area of cultivated land, garden land and wetland and the phosphorus content of lake, and there is a positive correlation between the area of forest land, pasture land, construction land and phosphorus content of lake. There is a negative correlation between wetland area and lake nitrogen content, a positive correlation between construction land area and lake nitrogen content, and a negative correlation between garden land area and cultivated land area and pollution index. There is a negative correlation between the area of construction land and the comprehensive index of pollution. Dianchi Lake, Lugu Lake, Yangzonghai, Fuxian Lake, Xingyun Lake and Chenghai are in the conflict zone, Erhai Lake and Yilong Lake are in the process of transition from conflict zone to coordination zone.
