【摘要】：研究目的:根据开发适宜性与土地利用效率的空间协调关系,判断江苏省县级单元的空间开发合理性状态。研究方法:基于经济社会发展、交通可达和生态约束3方面因素评价江苏省空间开发适宜性,运用数据包络模型测度江苏省土地利用效率。研究结果:(1)空间开发适宜性方面,高适宜区域主要分布在苏锡常和南京,中适宜区域位于苏中地区和苏北地级市、县(市)的城区,低适宜区域主要分布在苏北的非建设用地上;(2)空间开发效率方面,综合效率呈现南高北低的格局,高效率县市主要分布在长江以南区域,规模递增仍然是苏北和苏中地区投入产出的主要特征,但其建设用地投入存在冗余现象;(3)匹配关系方面,开发适宜性与土地利用效率协调类型以苏南地区的"HH"型、苏中地区的"MM、MH"型和苏北地区的"LL"型为主,高适宜区域普遍具有较高的开发强度。研究结论:江苏省大部分县市(区)的空间开发适宜性和开发效率是基本协调的,但部分地区仍然存在开发过度和土地利用效率低下的问题。
[Abstract]:Objective: according to the spatial coordination relationship between development suitability and land use efficiency, the rational state of spatial development of county units in Jiangsu Province was judged. Methods: based on the three factors of economic and social development, traffic accessibility and ecological constraints, the suitability of spatial development in Jiangsu Province was evaluated, and the land use efficiency of Jiangsu Province was measured by using the data envelopment model. The results are as follows: (1) in terms of space development suitability, the high suitability areas are mainly located in Suzhou and Nanjing, the middle suitable areas are located in the central Jiangsu region and the prefecture-level cities in northern Jiangsu, and the counties (cities) are located in the urban areas. The low suitable area is mainly distributed on the non-construction land in the north of Jiangsu province. (2) in the aspect of space development efficiency, the comprehensive efficiency shows the pattern of high, north and low in the south of the Yangtze River, and the high efficiency counties and cities are mainly distributed in the south of the Yangtze River. Increasing scale is still the main feature of input and output in north and middle Jiangsu, but the input of construction land is redundant. (3) in the aspect of matching relationship, the type of coordination between development suitability and land use efficiency is "HH" type in southern Jiangsu. The "MMMH-MH" type in the central Jiangsu area and the "LL" type in the northern part of Jiangsu Province are the main ones, and the high suitable areas generally have high development intensity. Conclusion: the spatial development suitability and development efficiency of most counties and cities in Jiangsu Province are basically coordinated, but the problems of over-exploitation and low land use efficiency still exist in some areas.
