摘要
要:研究的目的在于揭示城镇用地"经济—社会—生态"绩效的空间分异与绩效障碍,并提出政策建议。研究以江苏省为研究区,基于经济、社会和生态统计数据,分别采用绩效评价模型和障碍度诊断模型对江苏省61个县域城镇用地进行绩效评价与障碍度诊断。研究发现,江苏省城镇用地综合绩效呈现出苏南最大、苏中次之、苏北最小的空间格局,经济、社会、生态绩效分别具有不同的空间分异特征。在主导障碍因素方面,苏南地区主导障碍因素是社会障碍因素,而苏中和苏北地区主导障碍因素是经济障碍因素。因此,面对江苏省县域城镇用地中存在的绩效障碍问题,需要减弱城镇用地绩效主导障碍、缩小地区内部县域城镇用地绩效差异、坚持"经济—社会—生态"绩效协调发展。
The purpose of this study is to analyze spatial differentiation and hindrance of urban land use based on the economic-social-ecological performance and advances counter-measures. Using the social, economic and ecological data of 61 counties in Jiangsu Province, we construct a land use performance evaluation model and a hindrance diagnosis model to analyze spatial differentiation and measure the hindrance degree. Our results show that the comprehensive performance of land use in Jiangsu Province presents a spatial pattern with a decreasing ranking of ＂Southern Jiangsu-Central Jiangsu-North Jiangsu＂, and the economic, social and ecological performance shows different spatial differentiation characteristics. The economic performance shows spatial characteristics with a decreasing ranking of ＂Southern Jiangsu - Central Jiangsu -Northern Jiangsu＂. Social performance does not show a significant differentiation state. Ecological performance shows a spatial pattern the same with that of economic performance. As for intra-regional spatial difference, the economic performance shows spatial characteristics with that ＂Southern Jiangsu is the largest, followed by Central Jiangsu and Northern Jiangsu＂. In terms of the social performance, there are significant spatial differences between Southern Jiangsu and Central Jiangsu, while the difference is trivial in the Northern Jiangsu. The ecological performance presents a pattern that Central Jiangsu is the best, followed by Southern Jiangsu and Northern Jiangsu respectively. The dominant hindrance factors of Southern Jiangsu are social factors, while in Central and North Jiangsu, the dominant factors are economic hindrance factors. With the hindrance problem of land use in Jiangsu, it is necessary to weaken dominant hindrance, improve the land use performance on county level, fill the gap between counties, and stick to the ＂social-economic-ecological＂ performance framework and the coordinated development.
