摘要:
随着发达地区经济社会的快速发展,建设用地急剧扩张,改变地表下垫面水文条件,成为导致区域水环境不断恶化的重要因素,并引发一系列的资源环境问题.为了促进资源环境与经济社会均衡发展,近年来地理学界开展了大量空间开发功能分区和适宜性分区的研究,为区域空间管理和建设用地调控提供科学依据,但是这些研究大多以单一行政区为对象,缺少流域等跨行政区的自然地理单元的分区研究,忽视了流域经济社会发展与资源环境保护的整体性.为此,本文在借鉴相关分区研究的基础上,以太湖流域为例,探讨了流域单元空间开发适宜性分区指标选择与综合评价等技术方法,将太湖流域划分为高适宜区、中等适宜区、低适宜区和不适宜区等四种类型,并采用数据包络分析方法,探讨了建设用地配置规模与空间开发适宜性的对应关系和均衡程度,据此判断流域空间开发的失衡状态.

Regionalization of spatial development suitability and evaluation of spatial unbalance in Taihu Basin
SUN Wei
Abstract:
Along with the rapid development in developed areas, rapid expansion of construction land has caused changes of underlying surface hydrological conditions which could be an important factor for deterioration of water environment, and trigger series of environmental problems. In recent years, in order to coordinate the relationship between environment and economic development, many studies on spatial potential development regionalization have been carried out, which provides scientific basis and regulations for regional government on construction sprawl control. But most of these studies chose single administrative region as object, which lacks geographical unit of regional zoning across various administrative, and neglects the integrity of development with resource protection. The present study, based on existing related regionalization method, discusses the method of choosing indicators and evaluation in the scale of basin area. As a case study, Taihu Basin is divided into four types:high suitable areas, medium suitable areas, low suitable areas and non-suitable areas. By using data envelopment analysis method, the present study has explored the correspondence relationships between construction land, resource environmental capacity and development potential, and the unbalance situation of construction land distribution is assessed. The result can provide scientific basis for coordinating economic development and natural resources management, and making polices of space governance.
Key words:  Spatial potential development regionalization  spatial unbalance  Taihu Basin
