Ecosystem service value (ESV) included some contributions of ecological environments to human health and living, and provide cultural and economic benefits for sustaining and fulfilling living organisms. The author selected the Ebinur lake Wetland Nature Reserve as our study site to analyze the spatial distribution and dynamics of ecosystem services, and we used 1972, 1998, 2006, 2014 and 2016 images to study land use/cover change (LUCC) over these periods. LUCC is one of the key drivers that affect ecosystem services. Firstly, in 1972-2030, land use/cover (LULC) significantly changed, with all LUCC practices increasing except for the categories of water area, bare land area and barren land/other. Secondly, changes in ESV were significant during the last 60 years. The total annual ESV in the study area decreased by 50.89% between 1972 and 2030, mostly attributable to the 6.82% growth of saline land, 0.09% growth of desert, 1% decrease of wetlands and 0.95% decrease of water bodies. Thirdly, the spatial-temporal variation of ESV was prominent. Spatial correlation was significant, and the degree of spatial clustering was relatively high in the study area, which was mainly distributed in the water body and wetland regions, and these high-value regions exhibited a decreasing trend. Low values occurred around the lake areas, which increased over time.
生态系统服务价值(ESV)包括生态环境对人类健康和生活的一些贡献,并为维持和满足生物的生存提供文化和经济效益。作者选择艾比湖湿地自然保护区作为研究地点,分析生态系统服务的空间分布和动态变化,并使用 1972 年、1998 年、2006 年、2014 年和 2016 年的图像来研究这些时期的土地利用/覆盖变化(LUCC)。土地利用/覆盖变化(LUCC)是影响生态系统服务的关键驱动因素之一。首先,在 1972-2030 年期间,土地利用/覆盖(LULC)发生了显著变化,除了水域、裸地和荒地/其他类别外,所有 LUCC 实践均有所增加。其次,在过去的 60 年里,ESV 发生了显著变化。研究区的总年度 ESV 在 1972 年至 2030 年间减少了 50.89%,主要归因于盐渍地增加了 6.82%,沙漠增加了 0.09%,湿地减少了 1%,水体减少了 0.95%。第三,ESV 的时空变化明显。空间相关性显著,研究区的空间聚类程度相对较高,主要分布在水体和湿地地区,这些高值区域呈下降趋势。低值区主要分布在湖泊周围,且呈增加趋势。
