摘　　要：开展快速城市化区ESV定量化描述是理顺生态环境和经济协调发展的有效手段。基于三期遥感解译数据,采用农田粮食单位面积产量比值、生物量和植被覆盖度修订价值当量表,定量分析了重庆都市区2000—2015年ESV时空演变及驱动因素。结果表明:(1)研究区生态系统类型以森林和农田为主,森林主要分布在“四山”山脊,农田主要分布在平坝槽谷地带;(2)时段内城市变化最为显著,空间上向南、北、西3个方向快速扩张,增幅高达225.90%;(3)15 a间总ESV从278.51亿元增加到297.71亿元,年均增幅0.7%;生态系统类型中,水域ESV增加最为显著,增幅高达60.56%;研究区以水文调节服务功能为主,且增加最为明显;(4)研究区ESV密度高值主要集中在“四山”山脊、长江和嘉陵江干流及南部桃子荡山等低山区;时段内“四山”和“两江”干流等区域价值密度呈增加趋势,减少主要集中在西部缙云山与中梁山间的槽谷平坝区及中部都市核心区域。(5)研究区ESV与城镇化率呈显著负相关,与林业生产总值呈显著正相关,表明研究区ESV与社会经济发展相互耦合,通过合理调控社会经济结构可以使区域ESV保持在高水平。Quantitative description of ecosystem service value(ESV)in rapidly urbanized areas is an effective means to straighten out the relationship between ecological environment and economic development.Based on the three-phase remote sensing interpretation data of Chongqing Metropolitan Area,the spatio-temporal evolution characteristics and driving factors of ESV in this region from 2000 to 2015 were comprehensively analyzed.The results show that:(1)the ecosystem types in the study area are mainly forest and farmland,and the forests mainly distribute in the‘Four Mountains’ridges running from north to south,the farmlands mainly distribute in the flat dam trough;(2)during the period,the urban ecosystem changes most significantly,and the space expands rapidly towards the three directions of south,north and west,with an increase of 225.90%;(3)the total ESV increases from 27.851 billion yuan to 29.771 billion yuan within 15 years,with an average annual increase of 0.7%;among all ecosystem types,the ESV increases in water body is the most significant,with an increase of 60.56%;from the perspective of various types of ecological service functions,the hydrological regulation service function is the main function in the research area,and the increase is the most significant;(4)the high value density of ESV in the study area mainly concentrates in the‘Four Mountains’ridge,the mainstream of the Yangtze River and Jialing River,and the low mountain areas such as Taozidang Mountain in the south;in spatial change,the increase of value density mainly concentrates in the‘Four Mountains’and‘Two Rivers’mainstream,and the decrease mainly concentrates in the trough valley and Pingba area between Jinyun Mountain and Zhongliang Mountain in the west,as well as in the central urban core area;(5)the results of driving mechanism analysis show that the ESV in the study area is negatively correlated with the urbanization rate,and positively correlated with the gross forestry product,showing that ESV in the study area is coupled wit
