摘要

以关中-天水经济区各市区为研究对象

依据水土流失的相关理论

运用生态学和经济学思想并结合遥感影像进行估算

采用主成分方法对粮食生产过程的生态成本和直接生产成本进行了研究。研究结果表明

关中天水地区粮食生产的生态成本最高已经达到0.8元/kg

直接生产成本约为1.45元/kg

总成本约为2.25元/kg

已经接近粮食的出售价格2.56元/kg。水土流失对于关中-天水地区粮食的生态成本具有重要影响

种子费用和机械费用过高是制约粮食生产成本过高的关键因素。高成本低收益的情况会极大地削减农民种植粮食的积极性。因此

在今后的种植过程中

应当充分利用农业资源

加大科技投入

扩大种植规模

降低生产单位粮食的生态成本。

Abstract

The paper analyzed the ecological cost and direct cost of grain production in the Guanzhong-Tianshui Economic Zone using the principal component analysis based on the theories of ecology

economics and water and soil conservation combined with remote sensing image.The results demonstrated that the ecological cost of grain production reached to 0.8yuan/kg

direct cost of production was about 1.45yuan/kg

which led the total cost of 2.25yuan/kg close to the sale price of 2.56yuan/kg in Guanzhong-Tianshui area.Soil erosion was an important factor affecting the ecological cost of food production and high seed price and machinery expense are the key factors that caused high food production cost.The situation of high cost and low income would significantly discourage farmers engaging in the food production therefore it is important to make full use of agricultural resources

increase investment in agricultural science and technology and expand the farming scale in order that the unit ecological cost of food production be reduced.
