我国省级耕地非农化适度性评判研究

Primary Research on the Evaluation of the Rates of Farmland Conversion at the Provincial Level in China

对我国省级耕地非农化的适度性做出评判,将有助于耕地保护政策的有效实施。为此,从耕地非农化与经济发展关系的角度提出了一种评判区域耕地非农化适度性的方法,并运用此方法对我国近年来各省市区耕地非农化的适度性进行了实证研究。结果表明:即使在全国耕地非农化总体适度的情况下,仍然存在某些耕地非农化过度或滞后的省份。因此,对于那些耕地非农化过度的省份必须采取紧的土地供应政策,而对于那些耕地非农化滞后的省份则应采取松的土地供应政策,这样做才能既调控了耕地非农化,又不会影响经济的正常发展。

Making a rational judgment of degrees of farmland conversion in provincial level will bring farmland protection policies into action efficiently in China. Therefore, in this paper, we explored a method to comment and judge the degrees of farmland conversion based on the correlation between farmland conversion and economic growth. With that method we studied the degrees of farmland conversion in provinces in China from 1999 to 2002. The results showed that even if the degree of farmland conversion was totally proper in nationwide, there existed farmland over-conversion and delayed-conversion in the provincial level. So we should enforce a tight land supplying policy upon the provinces of which farmland conversion were over and an easy one upon the provinces of which farmland conversion were delayed. If that can be done, we will control the farmland conversion without stopping the normal economic growth.
