崇阳县耕地后备资源的质量潜力测算

Potential Quality Calculation of Reserve Resources of Cultivated Land of Chongyang County

准确分析评价和测算耕地后备资源的潜力是对其进行开发利用的前提。以湖北省崇阳县为研究区,参照农用地分等定级的技术方法,确定分等的因素指标和权重,计算崇阳县耕地后备资源自然质量等指数,划分自然质量等别,并借助湖北省二级区的耕地产能核算模型计算其理论产能,以此来测算耕地后备资源的质量潜力。通过计算结果可知,崇阳县耕地后备资源总潜力产量为3986.0205×104kg,在空间分布上大体呈现从西北向东南递减的趋势。

Accurate analysis and calculation is a prerequisite for the development and utilization of the reserve resources of cultivated land. This paper studies on Chongyang County, Hubei Province, chooses classification factors and weighs according to the Rules for classification of agricultural land. Then calculates the natural quality of cultivated land reserve resources in Chongyang County and divides natural quality leveis. And then calculates the theoretical capacity by the model of cultivated land productivity, in order to calculate the potential quality of reserve resources of cultivated land. The calculation results show that the total theoretical potential of arable land reserve resources in Chongyang County is 3986.0205 × 10^4kg and the potential quality decreases from northwest to southeast in space distribution.
