Abstract: 【Objective】 This paper takes the Tarim River basin, a typical inland basin, as the research area to explore the spatial and temporal evolution trend of ecosystem services under land use change in the Tarim River basin, so as to provide scientific basis for the sustainable development of land resources in arid areas. 【Methods】 The study applies spatial correlation analysis using Landsat TM remote sensing images for 1990, 2000, 2010 and 2018. The land use data is extracted and the ESV coefficients are adjusted accordingly. 【Results】 (1) From 1990 to 2018, land use in the Tarim River Basin changed significantly. Construction land and cultivated land exhibited an increasing trend, while High, medium and low coverage grassland, forest land and water indicated a decreasing trend. Construction land increased the most, while water decreased the most. (2) Overall, ESV in the Tarim Basin charted a downward trend, from 872.884 billion yuan in 1990 to 767.165 billion yuan in 2018. From 2015 to 2018, the Basin’s ESV suffered the largest declines, with grassland ESV accounting for over 39% of the loss and adjustment services accounting for over 62%. 【Conclusion】 During the study period, the spatial distribution of ESV in the study area showed spatial distribution characterized that was either high in all directions or low in the middle, with significant positive spatial autocorrelation. The spatial distribution of ESV dynamic changes showed that ESV value-added regions were distributed in the southeast portion of the study area, while the ESV loss regions were distributed in the western and northern portions of the study area.

摘要: 【目的】 研究塔里木河流域1990~2018年间土地利用变化下生态系统服务价值时空演变趋势,为干旱区土地资源的可持续发展提供科学依据。【方法】 基于1990、2000、2010和2018年4期Landsat TM遥感影像,提取土地利用数据并采用修正后生态系统服务价值系数、空间相关性分析等方法,以典型内陆盆地塔里木河流域为研究区,研究塔里木河流域土地利用与生态系统服务价值(Ecosystem services values,ESV)的时空演变特征。【结果】 (1)1990~2018年间塔里木河流域土地利用变化显著,耕地和建设用地表现为增长趋势;高、中、低覆盖度草地,林地和水域呈现减少趋势;建设用地的涨幅最大,水域的降幅最大。(2)流域内ESV总体上呈现下降趋势,由1990年的8 728.84×108元减少到2018年的7 671.65×108元;2015~2018年ESV减幅最大,其中草地ESV占比最高,达39%以上;单项ESV以调节服务为主,占比在62%以上。【结论】 研究区ESV在空间分布上表现为四周高、中间低的特征,且具有显著的空间正向自相关性;ESV增值区域分布在研究区东南部区域,ESV损失区域分布在研究区西部和北部区域。
