摘要: 为量化分析耕地生态系统服务价值及其与区域经济发展的空间关系,采用改进的耕地当量因子,对甘肃省2014年耕地生态系统服务价值进行定量化研究,并采用双变量空间自相关探讨其与区域经济发展在空间上的关联关系。结果表明:(1)在GPP修正的基础上估算得到的甘肃省2014年耕地生态系统服务价值为4.96×1011元,其中水资源供给功能的价值为负,食物生产功能的生态系统服务价值相对较高,美学景观功能的生态系统服务价值最低。(2)双变量空间自相关显示人均国内生产总值与耕地生态系统服务价值在空间上存在显著的负相关关系,Moran’s I指数为-0.252 3。局部双变量空间自相关LISA图也显示低—高聚集区主要分布在经济发展相对落后、具有明显生态优势的东南部地区;而高—低聚集区则主要分布在经济高速发展,生态环境相对恶劣的西北部地区。研究结果可为甘肃省生态环境管护与区域经济发展提供决策参考,为实现经济增长与生态保护统筹协调发展提供参考依据。

Abstract: Ecosystem service links the natural ecosystems and socioeconomic systems,and it is a hot topic in ecology,geography and other disciplines.The cultivated land ecosystem is closely related to the national food security,therefore,to quantify the ecosystem service value of cultivated land and analyze its relationship with regional economic development have great significance.This study uses an improved equivalent factor of cultivated land to quantify the ecosystem service value of cultivated land in Gansu Province,China,in 2014,and uses the method of spatial autocorrelation to explore the spatial relationship between the cultivated land ecosystem service value and regional economic development at the county scale.The results showed at follows:(1) As a supply land of the major food,the ecosystem service value of cultivated land of Gansu Province was 4.96×1011 yuan in 2014,and its food production function is relatively high,and the relatively backward economy has basically resulted in its relatively low aesthetic landscape function. (2) The univariate spatial autocorrelation indicated a significant positive correlation in space between its per capita GDP and the ecosystem service value of cultivated land in the areas with good regional economic development.The bivariate spatial autocorrelation indicated a significant negative correlation in space between its per capita GDP and the ecosystem service value of cultivated land.And the Moran'sI index is 0.510 6 and 0.604 1 respectively.The global Moran's I index is -0.252 3.The local bivariate spatial autocorrelation LISA map also shows that the Low-High areas were mainly distributed in the southeastern area where the economic development is relatively backward and there is obvious ecological advantages;however,the High-Low areas were basically the opposite.This research can provide decision-making reference for ecological environment management and protection and regional economic development of Gansu Province,and can also provide reference for the coordinated development of economic growth and ecological protection.

Key words: ecosystem service value (ESV), regional economic development, bivariate spatial autocorrelation, Gansu Province
