摘要
该文阐述了农田生态服务价值的概念、研究的思路与方法,对9项调节因子的计算作了介绍。研究表明,中国粮食主产区农田单位面积生态服务价值平均为4044.55元/hm2.年,比全国平均水平高出14%;三大平原农田总生态服务价值为3128.82亿元/年,总体占全国的67.82%。东北平原单位耕地和人均农田生态服务价值均高于华北平原和长江流域。
This paper expounds the concept of farmland ecologic service value, research thought and method; introduces the calculation on 9 regulating factors. Results indicate that the average value for ecological service per unit farmland area is 4044.55 yuan/hm^2 in major grain production region of China. This is 14% higher than the national average level. The total value for ecological service of the 3 large plain farmlands is 3128.82 hundred million Yuan per year, which takes 67.82% of the country's total. The farmland eco- logical service values per unit area and per capita for the Northeast Plain are higher than that of the North China Plain and the Yangtze River Valley.
