陕西省城市土地集约利用评价及其区域差异研究

城市土地集约利用关系到城市的可持续发展问题，通过建立陕西省城市土地集约利用评价指标体系，以SPSS 16.0及SUPERMAP软件为平台，利用主成分分析法（PCA）对陕西省10个地级市的城市土地集约利用状况进行了评价研究，并分析了陕西省10个地级市土地集约利用的区域差异。结果表明:陕西省10个城市的土地集约利用程度具有较大的差异，从空间上表现为:关中地区较高，陕北次之，陕南较低的特点。土地集约利用呈现出的空间差异与三个区域的经济发展和区位有一定的关系。陕西省要在加大城市土地投入强度、提高土地经济效益和土地利用强度的同时发挥关中的区域辐射和带动作用，协调区域经济发展，提高城市土地集约利用效率。

Evaluation of Urban Land Intensive Use and Its Regional Differences in Shaanxi Province

Ubran intensive land use concerns the sustainable development of the city. In this paper, the evaluation index system of the urban land intensive use was constructed, urban intensive land use of the 10 cities in Shaanxi Province was evaluated by the method of the principal component analysis (PCA) and the software SPSS 16.0 and SUPERMAP, furthermore, the spatial differences of the urban land intensive use were analyzed, the results show that the degree of the intensive land use of 10 cities in Shaanxi Province is quite different, Guanzhong area is higher, the northern Shaanxi is the second and the southern Shaanxi is the lowest,and there is a certain relationship between the regional differences of intensive land use and the economic development and location of the 3 regions in Shaanxi Province. Shaanxi Province should increase the city land investment intensity, improve the economic benefits, the land use intensity and sustainable utilization degree, act as the radiating and leading role, and coordinate the development of regional economy in order to improve the level of urban intensive land utilization in Shaanxi Province.
