摘要:

【目的】 研究土地利用变化背景下生态系统服务功能改变对干旱区生态建设与区域可持续发展的影响,为新疆喀什地区土地利用规划提供依据和参考。【方法】 以1978、1988、1998、2008和2018年5期的土地利用遥感解译数据为基础,采用我国陆地生态系统服务价值测算方法,估算新疆喀什地区1978~2018年41a间各土地类型变化及其生态系统服务产生的影响。【结果】 (1)41a间,耕地、林地、湿地、建设用地和沙地面积扩大,而草地、水域、未利用地和盐碱地面积缩小;(2)41a间喀什地区总生态系统服务价值呈“减少—增加—减少”的变化趋势,呈现减少趋势。总生态系统服务价值从1978年的593.23×108元减少到1988年的585.06×108元,在1998年增加到592.89×108元,而到2018年的生态服务价值又减少到552.70×108元;(3)水源涵养和废物处理功能的价值贡献最大,而食物生产和原材料的价值贡献最小,新疆喀什地区生态服务功能属于调节性功能;(4)41a间,新疆喀什地区各土地类型各年份的生态系统服务价值敏感性指数均小于1,新疆喀什地区总生态系统服务价值对其价值系数缺乏弹性。【结论】 近41a来喀什地区土地利用变化与社会经济建设活动相吻合,引用生态服务价值系数运用于喀什地区土地利用变化对其生态系统服务功能变化的研究,有助于定量的分析喀什地区土地利用结构变化的生态效应。

Abstract:

【Objective】 The aim of this study is to analyze the impacts of the ecosystem service function change on ecological construction and regional sustainable development in arid areas, and through this to provide scientific basis and practical reference for land use planning, ecological civilization construction and regional sustainable development of Kashgar Prefecture. 【Methods】 【Results】 (1) From 1978 to 2018, significant land use change happened in Kashgar. During the process of land use change, the area of cultivated land, forest land, wetland, construction land and sandy land increased while the area of grassland, water land, unused land and salinized land decreased. (2) From 1978 to 2018, the value of ecosystem services in Kashgar showed a "reducing-increasing-decreasing" trend, and the whole study period exhibited a decreasing trend. The total value of ecosystem services decreased from 593.2×108 Yuan in 1978 to 585.1×108 Yuan in 1988, and then increased to 592.9×108 Yuan in 1998 then decreased to 552.7×108 Yuan in 2018 again. (3) The analysis of the ecosystem service function composition indicated that the water supply and waste treatment function were the top ecological functions with high service value, while the food production and raw material function were the two low ecological functions with small service value. The result indicated that, the Kashgar ecosystem function belonged to regulating function. (4) From 1978 to 2018, the sensitivity index of ecosystem service value of each land type in Kashgar was less than 1, indicating that the value of ecosystem service in Kashgar lacked elasticity. 【Conclusion】 The study results indicated that, in the past 41 years, the land use change in Kashgar has coincided with social and economic construction activities, which explained that the application of the Eco-service value coefficient of Xie Gaodi in this study is helpful to the quantitatively analysis of the ecological effects of the land use structure change in Kashgar Prefecture.
