摘要 为探究区域耕地生态价值的时空变化，构建了抚州市耕地生态价值评估体系，在利用物价指数修正法对相关价格进行修正的基础上，运用替代工程、市场价格和系数修正等方法对2009—2017年抚州市的耕地生态价值进行了综合评估与测算。结果表明，2009—2017年抚州市耕地生态总价值总体呈现缓慢上升但中间略有波动趋势，其中2009年最低为370.05×107元，2017年最高为413.21×107元，2017年较2009年净增43.16×107元;2009—2017年抚州市各个区县的耕地生态总价值整体上呈现稳定增长的趋势，中间略有波动，耕地生态总价值呈现出从西北向东南方向递减趋势;2009—2017年抚州市各区县耕地负向价值呈现出先增加后下降的变化趋势，农业发达的区县带来的耕地负向价值相对较高。研究结果为抚州市耕地生态环境保护以及耕地补偿等提供科学依据。

Abstract In order to explore the temporal and spatial changes of the ecological value of cultivated land，the ecological value evaluation system of cultivated land in Fuzhou is constructed.Based on the use of the price index correction method to modify the relevant prices， the alternative engineering， market price， and coefficient correction methods are used to evaluate the ecological value of cultivated land in Fuzhou from 2009 to 2017.The calculation results show that the total ecological value of cultivated land in Fuzhou City showed a slow rise but a slight fluctuation in the middle from 2009 to 2017.The lowest value in 2009 was 370.05 × 107 and the highest in 2017 was 413.21×107 yuan， a net increase of 43.16×107 yuan in 2017 compared with 2009; the total value of the cultivated land ecological value in various districts and counties of Fuzhou in 2009-2017 showed a steady increase overall， with slight fluctuations in the middle， and the total cultivated land ecological value.The value showed a decreasing trend from northwest to southeast; from 2009 to 2017， the negative value of cultivated land in various districts and counties of Fuzhou showed a trend of first increase and then decrease.The negative value of the cultivated land brought by the districts and counties reached a relatively high level.The research results provide scientific basis for the ecological environment protection and cultivated land compensation of cultivated land in Fuzhou.

耕地資源是中国重要的基础性、战略性资源，保护耕地资源是国家重大战略[1]，我国政府高度重视耕地保护，将其列入基本国策，采取“世界上最严格的耕地保护政策”[2]，但长期以来对耕地资源的价值理论认知存在缺陷，尤其是耕地生态价值和社会价值一直被忽视，耕地保护的价值和非农化损失价值远远超过传统意义上的经济价值，故全面认识耕地的价值是保护耕地的关键。2000年以来，随着全球城市化进程的加快，生态系统服务稀缺性变得越来越突出，耕地生态系统的多功能性受到了空前的重视，国外有关农地价值，特别是耕地生态价值的研究成为热点。……
