长沙高新区土地利用的可持续性评价研究

Evaluation on the Sustainable Use of Land in Changsha Hi-tech Zone

以长沙市河西高新技术开发区为研究对象,从影响开发区土地可持续利用的用地面积、用地效益、用地结构和用地管理四个方面选取22个指标构建土地可持续利用的评价指标体系,结合收集的相关数据运用综合分析法确定各指标权重,在此基础上对高新区土地利用的可持续性进行综合评价,结果表明:1996—2006年该区土地的可持续性利用水平是一个从较低到较高的发展过程,该区土地利用存在配套基础和公共服务设施缺乏、土地有闲置现象、产业用地结构不合理等问题。应通过改变开发区投资环境、注意开发区的分期建设、优化产业结构等措施,提高该区土地利用的可持续性。

Since the idea of the sustainable development was proposed in 1990s, much research has been carried out in relation to sustainability in land use at the county and city levels. But, little is known in respect to the sustainability of land use at the level of development zone. In combination with the special function - oriented development zone, the index system for evaluating land use sustainability in development zone is constructed in this paper and is applied to evaluate the land use sustainability of Hexi Hi - tech Development Zone of Changsha. It shows that the land use sustainability is lower during the years from1996 to 1998, moderate during the years from1999 to 2004, and higher in 2005 and 2006.
