【摘要】：随着经济社会的发展,人地矛盾日趋严峻,导致土地利用在数量上与结构上发生了重大变化。湘潭市雨湖区作为长株潭城市群“两型”社会建设的重点区域,城市的发展势必影响用地结构的转变。为发掘雨湖区土地利用中存在的问题,促进土地的合理利用,本文运用GIS对湘潭市雨湖区2000-2010年各类用地的变化情况进行数量变化、空间变化、动态变化分析。在此基础上,结合定性与定量分析,探讨影响土地利用变化的驱动力。针对土地利用中存在的问题,提出相应对策。结果表明：(1)2000年——2010年,雨湖区的土地利用变化较为显著。除耕地和林地以外,草地、河流水面、建设用地和裸地的面积都在增加；耕地减少、建设用地增加的范围基本一致；裸地的年变化率最大,其次为草地。(2)在对土地利用变化驱动力定性分析时,自然驱动力主要包括气候、土壤、地质地貌和水文。社会经济驱动力包括人口因素、经济发展、政策制度。利用主成分分析法对其进行定量分析时,得出社会经济发展、人口增长、产业结构调整三个因素是促进雨湖区土地利用变化的主要驱动力,并且驱动力的影响程度在逐年增强。(3)雨湖区土地利用存在的主要问题是耕地与建设用地矛盾突出、土地利用集约化程度有待提高、土地污染较为严重。在此基础上,提出了土地可持续利用的对策建议,包括切实保护耕地资源、提高土地利用集约化水平、注重生态安全与环境保护、处理好经济发展与土地利用的关系。
[Abstract]:With the development of economy and society, the contradiction between man and land is becoming more and more serious, which leads to great changes in the quantity and structure of land use. As the key area of "two types" social construction of Chang-Zhuzhou-Xiangtan urban agglomeration, the urban development of Xiangtan City is bound to influence the transformation of land use structure. In order to explore the problems existing in the land use of Yuhu District and promote the rational use of land, this paper uses GIS to analyze the quantity, spatial and dynamic changes of various kinds of land use in Yuhu District of Xiangtan City from 2000 to 2010. On this basis, combined with qualitative and quantitative analysis, the driving force affecting land use change is discussed. According to the problems existing in land use, the corresponding countermeasures are put forward. The results show that: (1) in 2000-2010, the land use change in Yuhu Lake area is obvious. Except for cultivated land and forest land, the area of grassland, river surface, construction land and bare land are all increasing; the cultivated land decreases and the scope of construction land increase is basically the same; the annual change rate of bare land is the largest. Secondly, grassland. (2) in the qualitative analysis of the driving forces of land use change, the natural driving forces mainly include climate, soil, geology and geomorphology and hydrology. Social and economic driving forces include demographic factors, economic development, and policy systems. When the principal component analysis method is used in quantitative analysis, it is concluded that three factors are the main driving forces to promote the land use change in Yuhu District, such as social and economic development, population growth and industrial structure adjustment. And the influence degree of driving force is increasing year by year. (3) the main problems of land use in Yuhu District are that the contradiction between cultivated land and construction land is prominent, the degree of intensive land use needs to be improved, and the land pollution is more serious. On this basis, the countermeasures and suggestions for sustainable land use are put forward, including protecting cultivated land resources, improving the level of intensive land use, paying attention to ecological security and environmental protection, and dealing well with the relationship between economic development and land use.
