摘    要:土地利用/覆被变化将干扰生态系统的稳定供给能力,进而对生态系统服务和可持续发展构成威胁。以乌鲁木齐市为研究区,基于斑块生成土地利用模拟(Patch-generating land use simulation,PLUS)模型,模拟了2030年多情景下乌鲁木齐市的土地利用变化,并结合当量因子法、空间自相关分析等方法估算并预测了1990—2030年乌鲁木齐市生态系统服务价值(Ecosystem service value, ESV)及其权衡协同关系。结果表明:(1)1990—2020年乌鲁木齐市土地利用呈现“两增四减”变化趋势。2030年在惯性发展情景下,除林地外其他地类皆遵循历史演变规律;在生态保护情境下,建设用地面积萎缩,生态用地大幅增加;在综合开发情境下,建设用地面积有所增加的同时生态用地面积也处于上升状态;在重点开发情景下,城市建设用地扩张最为剧烈,耕地面积退化严重。(2)1990—2020年乌鲁木齐市ESV整体上呈现“V”型下降态势,共减少59.59×108元。2030年在生态保护情景下和综合开发情景下ESV处于增加趋势,在惯性发展情景和重点开发情景下ESV出现减少趋势。(3)2...

Abstract:Land use/cover change will interfere with the stable supply capacity of ecosystems, which in turn poses a threat to ecosystem services and sustainable development. Taking Urumqi City of Xinjiang, China, as the study area, this study simulates land use changes in Urumqi City under multiple scenarios in 2030 based on the patch-generating land use simulation (PLUS) model and combines the equivalent factor method and spatial autocorrelation analysis to estimate and project the ecosystem service value (ESV) and its trade-off synergy for 1990—2030 in Urumqi City. The results are as follows: (1) Land use in Urumqi City shows a trend of “two increases and four decreases” from 1990 to 2020. In the integrated development scenario, the area of built-up land increases, while the area of ecological land is also on the rise; in the key development scenario, the expansion of urban built-up land is the most drastic, and the area of arable land is severely degraded. (2) From 1990 to 2020, the trend of ESV in Urumqi City has a “V” shape. In 2030, ESV increases under the ecological protection scenario and the comprehensive development scenario and decreases under the inertia development scenario and the key development scenario. (3) Under the four development scenarios in 2030, the synergistic relationships among various ecosystem services in Urumqi City are primarily synergistic, with “high-high” and “low-low” synergistic aggregation areas coinciding highly with the distribution of high and low ESV values, and trade-off relationships sporadically distributed in local areas. These findings may serve as a basis for distributing ESVs in Urumqi City and can also provide scientific reference for the spatial planning of Urumqi City and the construction of ecological security patterns.
Keywords:ecosystem service value  PLUS model  multi-scenario simulation  trade-off synergy  Urumqi City
