四川省土地利用数量结构分析及土地可持续利用研究

运用多样化指数、集中化指数、区域组合类型以及区位指数对四川省及省内各地区的土地利用数量结构进行定量分析。研究表明,四川省的土地资源具有地域差异明显、组合类型数小等特征,同时也指出四川省在土地利用上存在人地矛盾突出、土地集约利用水平不高、宜农土地后备资源贫乏等问题,提出切实保护耕地、提高土地集约利用程度,加强土地开发和复垦,在土地管理领域发展循环经济等可持续利用的对策和建议。

Quantitative Structural Analysis of Land Use and Study on Land Sustainable Utilization in Sichuan Province

Based on the diversity index,concentration index,combination type and location index,the quantitative structure of land utilization in Sichuan province and its administrative areas are analyzed in this paper.It indicates that the land resource of Sichuan province presents several characteristics including the distinct regional difference,the small number of combination type,etc.Besides,the author points out the main problems of the land utilization as follows: the contradiction between man and land is outstanding,the level of land intensive utilization is not high enough,the reserved land resource suitable for cultivation is insufficient,and so on.Consequently the strategies for sustainable utilization of land are put forward,such as protecting cultivated land, raising the degree of land intensive utilization,strengthening the land exploitation and reclamation,developing circular economy in land administrative area.
