摘要
沿海经济发达地区的人均耕地资源短缺,工业化、城镇化快速发展对耕地的占用使耕地资源供给更趋紧张。从发展的角度,合理确定区域耕地资源容许城市、生态建设的占用量。具有重要价值和实践意义。基于对无锡工业化、城镇化进程中耕地资源态势。以及用地需求与耕地资源变化关系分析,构建了区域容许耕地转换模型(MAC),并应用该模型测定了无锡市2030年以前容许"非农"建设占用的耕地量。据此确定区域耕地保护的底线和调控指标,为快速工业化、城镇化进程中区域耕地资源优化利用提供一种新思路。同时,为多目标导向下的区域耕地资源优化配置提供量化方法和决策依据。
Rapid industrialization and urbanization have worsened the shortage of arable land resources in relatively developed coastal areas of China. It is important to study how to rationally allocate the quantity of arable land allowable for conversion into urban uses to maintain a sound eco-system both scientifically and practically. We constructed a Model of Allowable Conversion (MAC) of regional arable land resources after analyzing the characteristics of land resources changes, and studying the relationship between these changes and the demand for urban land use during the process of industrialization and urbanization in Wuxi city. With the assistance of the MAC we determined the maximum amount of arable land resources that is allowed for conversion into non-farming uses in the next 30 years. The idea of quantifying the allowable conversion of arable land resources will help accelerate the process of industrialization and urbanization while arable land resources are adequately protected. Through determining a threshold quantity of allowable conversion of arable land resources during industrialization and urbanization, we solved the problem of how to optimally allocate regional land resources for multiple and even conflicting demands for land resources.
