省域耕地和基本农田保有量测算——以黑龙江省为例

Estimation of Protection Area of Provincial Cultivated Land and Basic Farm Land——A Case Study of Heilongjiang Province

按照保障国家粮食安全、建设占用耕地占补平衡等要求,通过对耕地供需平衡分析和对耕地供给与需求的综合权衡,从区间估计的角度确定了省域耕地和基本农田保有量水平,形成黑龙江省耕地保有量的高、中、低保有量方案。以此为思路确定的耕地和基本农田保有量不再是一个点值,而是一个区间值,这更符合省级土地利用总体规划弹性控制的要求,为全国新一轮省级土地利用总体规划(2005—2020年)的编制及实施评价方法提供决策依据和理论支持。

Through comprehensive analysis of the balance between supply and demand of cultivated land,protection area of provincial cultivated land and basic farm land level was determined with the mode of interval estimation. Three programs of protection area of cultivated land were made based on the protection of national food security and cultivated land balance. Protection area of provincial cultivated land and basic farm land was no longer a point value, but a range of value based on this train of thought. This was more in line with the requirements of provincial land use planning flexibility control.This would provide policy - making basis and theoretical support for the new round of land use planning （2004 - 2020）of the province.
