通过十年间江苏省耕地资源利用的变化情况,从人口、经济、科技和城市化角度分析其变化的社会驱动因素;接着,对江苏省的耕地资源的可持续利用现状做出评价和预测未来的发展趋

摘要:农业是社会生产力的基石,是人类赖以生存和生产的需求。自从可持续发展的概念被提出以后,农业资源,尤其是耕地资源的节约、集约利用成为新的热门议题。如何达到耕地资源的可持续利用的目的是土地可持续的重要课题之一,而后者更被人们看作是国民经济发展的基础。本文笔者将以江苏省近年来耕地资源的使用现状为评价对象,从可持续的角度加以分析。文章主要架构如下:首先提出耕地资源可持续评价的相关概念,从耕地面积总量、人均耕地面积等方面指出江苏省耕地资源的利用现状;其次,通过十年间江苏省耕地资源利用的变化情况,从人口、经济、科技和城市化角度分析其变化的社会驱动因素;接着,对江苏省的耕地资源的可持续利用现状做出评价和预测未来的发展趋势;最后,为实现耕地资源的可持续利用与发展的目标提出一些建设性的建议。34944

Study on Sustainable Utilization of cultivated land resources——Taking Nanjing as an example
Abstract:Agriculture is the foundation of social productive forces and the guarantee of production and subsistence. Since the concept of sustainable development has been put forward, the intensive use of agricultural resources, especially arable land resources, has become a new topic. Sustainable use of cultivated land is the main link of sustainable land use, and sustainable land use is the basis of sustainable development of the whole national economy. In this article, the author think of the utilization of cultivated land resources in Jiangsu Province as the research object, from the perspective of sustainable analysis. The main structure of the article is as follows. Firstly, it proposes the concept of the sustainable use of land resources, and points out the status of utilization of cultivated land resources in Jiangsu province, according to the total area of cultivated land and the per capita arable land area. Secondly, , it analyzes driving factors   from the population, economy to science and technology through changes of the utilization of cultivated land resources during 2000-2009 in Jiangsu province. Then it assesses and forecasts the sustainable utilization of cultivated land resources in Jiangsu province. And finally, it puts forward constructive suggestions for the sustainable utilization and development of land resources.
