摘　　要：中原城市群是落实黄河流域生态保护和高质量发展国家战略的重要区域之一,为了给其生态管理策略优化提供参考,采用遥感模型和当量因子评价方法、GIS空间分析工具,定量评估了2000—2018年中原城市群的生态系统服务价值(ESV)并分析其时空变化趋势。研究结果显示:2000—2018年中原城市群ESV总体呈现出前期稳定向好、后期快速减小的趋势,其中2000年、2005年、2010年、2015年、2018年ESV总量分别为5880.98亿、5906.53亿、5906.56亿、5889.91亿、5797.80亿元;在各类生态系统中,农田和森林是主要贡献者,平均每年提供的ESV分别占ESV总量的48.0%、35.9%。研究时段内ESV增幅较大的生态系统类型有河流与湖泊、森林,ESV减幅较大的生态系统有农田、草地、湿地;研究时段内ESV增大的生态服务类型有水文调节、废物处理、提供美学景观,ESV减小的生态服务类型有食物生产、原材料生产、气体调节、气候调节、保持土壤、维持生物多样性;研究时段内总ESV冷热点空间分布相对稳定,热点在城市群西部和南部,冷点在中心城市郑州和大都市区;地均ESV冷热点分布表现出西部热点收缩、东部冷点扩张的趋势,其中热点由长治收缩至晋城,冷点由濮阳扩展至聊城。The central plains urban agglomeration is one of the important areas for implementing the national strategy of ecological protection and high-quality development of the Yellow River Basin.In order to provide a reference for the optimization of its ecological management strategy,remote sensing model and equivalent factor evaluation method,GIS spatial analysis tools had been used to quantitatively evaluate the ecosystem service value(ESV)of the central plains urban agglomeration from 2000 to 2018 and analyzed its temporal and spatial trends.The results show that from 2000 to 2018,the overall ESV of the region shows a trend of stability and improvement in the early stage and rapid decline in the later stage.The total ESV in 2000,2005,2010,2015 and 2018 are 588.098 billion RMB,590.653 billion RMB,590.656 billion RMB,588.991 billion RMB,and 579.780 billion RMB respectively;among various ecosystems,cultivated land and forests are the main contributors to ESV,and the average annual ESV provided by them accounts for 48.0%and 35.9%respectively of the total ESV;during the study period,the ESV increases largely in rivers,lakes and forests,and decreases in cultivated land,grassland and wetland;during the study period,the types of ecological services with increased ESV include hydrological regulation,waste treatment and provision of aesthetic landscapes.The types of ecological services with reduced ESV include food production,raw material production,gas regulation,climate regulation,soil conservation and maintenance of biodiversity;during the study period,a relatively stable spatial distribution of cold and hot spots of total ESV appears in the south and west of the urban agglomeration,central city Zhengzhou and metropolitan area.The hot and cold spot area of ESV per unit area shows a trend of shrinking in the west and expanding in the east,with the hot spot shrinking from Changzhi to Jincheng in the west and the cold spot extending from Puyang to Liaocheng in the east.
