【摘要】：滇池的水污染问题已经严重影响昆明经济社会的可持续发展。为估算因水污染造成的经济损失,首先利用滇池外海8个观测点的水质监测数据,应用时空地质统计学模拟滇池水体各污染因子浓度的分布,并依据水质指标的浓度分布对滇池水质区域划分为北部、中部、南部3个区域,然后从饮用水、渔业、旅游、灌溉4种水体功能入手,结合詹姆斯"浓度—价值曲线"模型和污染损失率法分别对滇池每个区域的水污染经济损失进行估算。通过计算,2010年滇池水污染经济损失总计72.75亿元,其中北部、中部、南部区域的水污染经济损失分别为15.52、37.59、19.64亿元。从各区域的污染损失率来看,滇池水资源饮用水源功能已丧失,渔业功能部分丧失(损失率90%),目前滇池水资源主要用于旅游和灌溉。
[Abstract]:Water pollution in Dianchi Lake has seriously affected the sustainable development of Kunming economy and society. In order to estimate the economic loss caused by water pollution, the water quality monitoring data of eight observation points outside Dianchi Lake were used to simulate the distribution of pollution factor concentration in Dianchi Lake by using spatio-temporal geostatistics. According to the concentration distribution of water quality index, the water quality area of Dianchi Lake was divided into three regions: north, middle and south. Then, the functions of drinking water, fishery, tourism and irrigation were analyzed. The economic loss of water pollution in each area of Dianchi Lake was estimated by using the James concentration value curve model and the pollution loss rate method. By calculation, the economic loss of water pollution in Dianchi Lake in 2010 is 7.275 billion yuan, and the economic loss of water pollution in the northern, central and southern regions is 15.52, 37.59, 1.964 billion yuan, respectively. According to the pollution loss rate of different regions, the function of drinking water source of Dianchi Lake has been lost, and the fishery function has been partly lost (90% of the loss rate). At present, the water resources of Dianchi Lake are mainly used for tourism and irrigation.
