城市化加速期维持我国耕地数量稳定的可行性分析

文章主要研究当前我国城市化加速发展时期,维持耕地数量基本稳定是否具有可行性。首先,采用文献归纳法,归纳总结已有的研究成果;然后,采取统计描述分析方法,运用遥感监测数据,分析我国城市化发展时期耕地变化的状况,并将我国城市化发展时期耕地变化状况与已有的研究结论进行对比研究,分析该时期耕地变化的主要驱动因素;最后,针对我国城市化加速发展时期耕地数量变化的主要驱动因素,采用统计和计量经济分析方法,进一步分析我国当前城市化加速发展时期维持耕地稳定的有利因素。研究结果认为:(1)我国前一时期的城市化发展已经基本完成了城市空间扩张,当前的城市建设应该主要整合已经占用的土地,在原有基础上加以集约利用,而不需要大量新增建设土地;(2)由于城市建设用地比农村建设用地更加集约化,城市化发展有利于阻止耕地流失;(3)我国生态退耕工程进入到巩固阶段,生态退耕面积有进一步减少的趋势;(4)我国后备耕地资源分布区域不均衡,通过异地占补平衡可以缓解经济发达省份耕地资源不足问题。因此,文章结论认为:城市化加速期维持我国耕地数量基本稳定具有可行性。

ANALYSIS OF FEASIBILITY MAINTAINING THE BASIC STABILITY OF THE ARABLE LAND AREA IN THE ACCELERATING PERIOD OF URBANIZATION

In recent years, a large number of arable lands have been occupied in the process of urbanization. How to protect the arable land area stability has become a major problem restricting the development of china. The main concern of this paper is, in the current period of rapid development of urbanization, whether it is feasible that the arable land area maintain basic stability. Through literature review, this paper summarized the results of the existing research using the remote sensing monitoring data and statistical analysis method, compared the findings of the existing research with the process of arable land change in China, analyzed the main driving factors of arable land change in urbanization process by the statistical analysis and logical way, and studied the favorable factors of maintaining the stability of arable land in China's current accelerated development period of urbanization. The results indicated that, during the period of China's current accelerated development of urbanization, the urbanization was conducive to the intensive use of land, ecological restoration area in our country was becoming smaller and smaller, the city construction and expansion had completed to occupy a large number of the arable land a few years ago, balance of land resources occupation and compensation in different provinces can alleviate the problem of cultivated land resources shortcoming in developed provinces. This paper suggested that it was feasible that the arable land area can maintain stable in the accelerating phase of urbanization.
