摘要
文章在分析区域土地利用结构变化与土地可持续利用相互作用机理的基础上,以原锡山市为例,分析了研究区域土地利用结构的多样化和集中化趋势,并着重通过构建灰色系统动态模型,预测了2005和2010年原锡山市土地利用结构的变化趋势,以及由此而对区域土地可持续利用的影响。根据论文的研究,原锡山市土地利用结构将呈现农业用地非农化、农业用地质量退化以及区域土地利用效率难以快速提高、区域土地后备资源日趋匮乏等变化态势,据此,论文最后从适度保护农地资源尤其是耕地资源、合理协调农业用地与非农业用地之间的相互关系、进一步完善区域土地利用政策体系以及提高科学技术对于土地资源的替代率等几个方面提出推进研究区域土地可持续利用的政策建议。
Based on analysis of mechanism of interactions between change in regional land use structures and sustainable land use, in a case study of Xishan City, trend of diversification and centralization of land use structure in the research region was analyzed and trend of changes in land use structure of Xishan City in year 2005 and 2010 and its effect on regional sustainable land use were predicted by rebuilding the Grey Systemic Dynamic Model. According to this research, the land use structure of Xishan City will show alienation of agricultural lands, degradation of agricultural land, hard-to-correct inefficiency of land use and increasing shortage of land resource reserves. Hereby, finally this paper brings forward some suggestions to advance the sustainable land use of the research region through protecting the agricultural land resource especially the resources of cultivated land, reasonably harmonizing the relationship between agricultural land and non-agricultural land, consummating the policy system for land use in the region and improving the rate of science and technology substitutinge land resource.
