城市居住用地整治效益评价指标与方法——以河北省邢台市为例

开展城市居住用地整治效益评价,不仅可以丰富土地整治领域理论研究内容,而且对于促进土地节约集约利用,推动城市用地的可持续发展,具有重要的现实意义。本文采用理论分析与专家咨询相结合的方法、GIS分析法、协调度模型,以河北省邢台市为例,评价了城市居住用地整治效益。研究结果表明:(1)城市居住用地整治效益评价指标可以从居住用地整治的经济、社会、生态和环境效益4个方面构建;(2)城市居住用地整治效益评价单元宜以宗地作为评价单元;(3)对邢台市居住用地整治效益评价结果显示全市总体上居住用地整治效益评价协调度均大于0.7,说明经过整治后,邢台市居住用地整治效益系统比较协调,整治后的经济、社会、生态和环境效益可以达到某种程度的协调发展,整治区域的综合效益比较高。研究结论:居住用地整治改变了用地结构与利用效率,改变了基础设施与公共设施的完善程度,也改变了用地的环境,这些变化会对区域发展产生重要影响。

Study on the coordinated development of the rural infrastructure and the rural economy

Through the construction of the comprehensive evaluation index system and the coordination degree model of the rural in- frastructure and the rural economic development level, the author carries out an empirical analysis on the rural infrastructure and economic coordinated development in the country＇s 31 regions. Research shows that the gap between the levels of the development of the rural in-frastructure in China is large, presenting the gradually reducing gradient distribution from the east to the west. The rural infrastructure de- velopment level has significant positive correlation with the level of economic development. For those provinces of the high development level of the rural economy, the infrastructure construction level is also relatively high. From the view of the coordination degree, it presents the obvious ＂dumbbell＂ shape, and there are more provinces which belong to the high quality coordination and the serious imbalance, with the coordinated degree in the eastern regions obviously higher than that in the central and western regions.
