摘要
在获取滇池湿地植物、水质、土壤等数据基础上,结合高分辨率卫星遥感影像数据,应用GIS技术,分析滇池湿地演变规律,并从经济、环境、社会、生态4个方面对滇池湿地进行效益评估。结果表明:2011年湿地和植物群落面积占整个环湖带面积的92.2%,与2007年相比,增长率为141.4%,湿地效益评估总价值增加了34.39亿元,滇池生态环境得到逐步改善。
Based on the collection data of the plants, water quality, soils of Dianchi Lake, and combined high resolution satellite remote sensing images, analyzed evolution law of Dianchi Lake wetland, and evaluated the benefits of Dianchi Lake wetland from economy, environment, society and zoology. The results showed that the area of wetland and plant community account for 92. 2% in lakeside zone, the rate of increase was 141.4% compared with 2007. The total value of evaluated benefits of Dianchi wetland increased 3.439 billion yuan, and ecological environment improved gradually.
