尉犁县土地利用/覆被变化的区域生态系统服务价值变化
|
摘要
基于尉犁县1993年、2001年、2009年和2017年的遥感影像数据,采用中国陆地生态系统服务价值测算方法,结合研究区实际情况,对生态系统服务价值系数进行了修正,分析了尉犁县土地利用/覆被变化导致的生态系统服务价值变化。结果表明:1993—2017年,尉犁县不同土地利用类型面积总体呈"六增三减"态势;即耕地、建设用地、水域、湿地、盐渍化地与沙漠面积有所增加,林地、草地与未利用地面积有所减少;尉犁县土地利用生态系统服务总价值总体呈增加趋势,从1993年的173.61亿元增加到2017年的206.30亿元,增加了32.69亿元。在整个研究时段内,研究区各土地利用类型对生态系统服务总价值的贡献大小从高到低依次为湿地>草地>未利用地>沙漠>水域>林地>耕地>盐渍化地>建设用地;敏感性分析结果表明各土地利用类型敏感性指数均<1,表明各土地利用类型生态系统服务价值对生态系统服务总价值的影响较小,缺乏弹性,研究结果可信。
Based on the remote sensing data of Yuli County in 1993, 2001, 2009 and 2017, the values of ecosystem services were amended by using the method of estimating the service value of land ecosystem in China and combining the actual situation of the study area. The change of ecosystem service value caused by the land use/cover change of Yuli County was analyzed. The results showed that in the period from 1993 to 2017, the total area of different land use types in Yuli County presented the ‘six increase and three decrease' pattern, i.e., cultivated land, construction land, water area, wetland, salinized land and desert area had increased, the areas of woodland, grassland and unused land had decreased, and the total value of land use ecosystem services in Yuli county rose. The value increased from 17.361 billion yuan in 1993 to 20.63 billion yuan in 2017, the net increase was 3.269 billion yuan. During the whole study period, the contribution of the land use types to the total value of the ecosystem services decreased in the order: wetland >grassland>desert>water body>woodland>cultivated land>salinized land>construction land; sensitivity analysis showed that the sensitivity index of each land use type was less than 1, which shows that the value of ecosystem services provided by land types has little influence on the total value of ecosystem services, lack of elasticity, and the results are credible.
