摘要:

通过探讨江苏省土地开发度与利用效益的空间特征、耦合格局及其协调发展程度,为相关研究提供参考。研究表明:① 1996~2015年,江苏省土地开发度指数从0.339升至0.426,呈现平稳增长→快速增长→平稳增长的态势。利用效益指数从0.459提高至0.596。 土地开发度与利用效益存在显著的空间差异。1996~2015年苏南地区土地开发强度高,利用效益提升显著。苏北地区的宿迁、淮安与盐城等市的利用效益较低,“中部凹陷”特征明显。③ 土地开发度与利用效益耦合关系处于不断变化过程中,总体耦合态势可划分为减弱-波动-增强3个阶段,土地开发与利用效益重心均向东南移动,但效益重心移动速度稍快。④ 苏南地区土地开发度与开发效益耦合度大于0.8,低值区集聚在淮安、盐城等地。

Abstract:

Rapid urbanization and industrialization have promoted the rapid expansion of construction land in Jiangsu. By clarifying and coordinating the relationship between land development and use benefit, it’s of great significance for the rational allocation of land resources to improve the coordination of interests and the compensation mechanism. In this article, the spatial distribution characteristics, the coupling pattern and the coordinated development degree of land development and use benefit discussed would provide the scientific reference for policy formulation. Our results show that: 1) During the study period, the index of the degree of land development rises from 0.339 to 0.426, showing a steady growth->rapid growth->steady growth trend. Meanwhile, the index on land use benefit increases from 0.459 to 0.596. 2) There are obvious spatial differences between land development and use benefit. In the last 20 years, the intensity of land development in South of Jiangsu is high, and the use benefit is also significantly improved. Suqian, Huai’an, Yancheng and other cities in the north of Jiangsu have low use benefit, leading to the formation of a significant phenomenon of "central depression". 3) The coupling degree between land development and use benefit is changing. The overall coupling situation can be divided into 3 stages, that is, the weakening, the fluctuation and the enhancement. Although the gravity centers of land development and use benefit are moving towards the southeast, the speed is faster. 4) The coupling degree of land development and use benefit is greater than 0.8 in South Jiangsu, and the low value of coupling is concentrated in Huaian, Yancheng and other places. Various factors, such as regional industrial development, infrastructure, land demand of human settlements, would produce different effects for land development and expansion intensity. The significant difference of land use policy and land intensive use level makes spatial variation on the feedback and degrees of coupling coordination degree between land development and use benefit.

Key words: degree of land development, land use benefit, spatial pattern, coordination analysis, Jiangsu
