【摘要】：在对土地利用功能类型划分的基础上,构建了多功能评价指标体系,对2000—2015年重庆市各区县土地利用多功能进行了动态分析。结果表明:(1)2005—2015年重庆市各区县土地利用总功能值一直在增加,呈主城向城市发展新区到渝东北、渝东南递减的空间差异。(2)重庆市各区县经济功能迅速提升,呈现主城区最强而其他区域较弱的空间分异。生态功能大部分提升,其功能值差异明显,功能实现率呈主城区较低,渝东北和渝东南较高的空间分异。社会功能提高较快,动态度大部分快速提升,呈主城和城市发展新区较高,渝东北、渝东南较低的空间分异。(3)在土地利用子功能指标中,农业生产功能值减弱,几乎全区县的经济发展、交通、就业支持、社会保障和居住家园功能均增强,空间差异缩小,资源供给和环境净化功能则呈主城区功能值较低,渝东北、渝东南值较高的空间分异。
[Abstract]:On the basis of the classification of land use function types, the multi-function evaluation index system was constructed. The dynamic analysis of land use multi-function of Chongqing city and county from 2000 to 2015 was carried out. The results showed that: (1) the total function value of land use in each district and county of Chongqing increased from 2005 to 2015, showing the main city to the urban development area to the northeast of Chongqing, Chongqing, Chongqing, Chongqing and Chongqing. The spatial difference of southeast decline. (2) the economic function of each district and county in Chongqing has been promoted rapidly, showing the strongest in the main city and weak in other regions. Most of the ecological functions have been promoted, the function value difference is obvious, the function realization rate is lower in the main city area, the northeast of Chongqing and the south of Chongqing is higher. The social function is faster and the dynamic degree is greater. Part of the rapid promotion, in the main city and urban development new area higher, Northeast Chongqing, Southeast Chongqing lower space differentiation. (3) in the land use sub function index, the function of agricultural production weakened, almost all district and county economic development, transportation, employment support, social security and residential home function are enhanced, space difference narrowing, resources supply and the net environment The function of the main city area is lower than that of Northeast Chongqing and Southeast Chongqing.
