该文运用数理统计分析耕地后备资源数量和类型的空间分异特征与分布规律,构建以投入产出比为基础,并以耕地转化潜力系数、耕地后备资源密集度系数加以修正的耕地后备资源开发时序模型,得到江苏各地区耕地后备资源的开发时序。研究结果表明,江苏省耕地后备资源具有明显的空间分异特征,根据开发时序模型提出江苏省各地区耕地后备资源的开发利用建议。 更多还原

【Abstract】 The purpose of this paper is to decide the exploiting priorities of reserving cultivatable land resources in different areas.Mathematical statistics method is used in the study.Taking Jiangsu Province as an example,this paper analyzes the spatial distribution features of land quantity and classification,and constructs a model of exploiting priority of reserving cultivatable land resources,which is based on the ratio of output by input,modified by the coefficient of potential transformation to cu...
