Study on Low Hilly Cities Land Suitability Evaluation Method Based on Ecological Considerations—A Case Study of Longfeng New Town in Sichuan

Attention to the development of low hilly cities increases, in order to guide their development towards efficient and ecological land use. This paper takes eco-safety into consideration in the future layout of land for construction, and incorporates ecological security factors into traditional methods of land suitability evaluation based on topographic conditions. Taking the Longfeng New Town in Suining City as an example, the GIS platform is used to superimpose various evaluation factors. The evaluation index system is determined using the combination of the Delphi Technique and AHP. The result of correcting traditional land suitability evaluation is obtained, which provides decision support for improving the scientificity of land use planning and layout.

城镇化水平综合测评与城镇用地分析

构建了一套城镇化水平综合测算的指标体系,把城镇化水平划分为人口城镇化水平、景观城镇化水平、经济城镇化水平、社会城镇化水平,采用多因素综合评价的方法,得到城镇化水平综合指数.对重庆市渝北区城镇化水平综合指数与城镇用地总规模、人均用地量、城镇用地效益进行相关分析,发现伴随城镇化综合水平的提高,城镇用地总规模不断扩大,人均城镇建设用地量有减少趋势,城镇建设用地经济效益有一定提高,据此对小城镇建设用地配置提出了建议.

重庆市渝北区城镇土地集约利用评价与空间格局分析

以重庆市渝北区35个乡镇为研究对象,建立小城镇土地集约利用评价指标体系,采用多因素综合评价法诊断城镇土地集约利用水平,按其分值将35个乡镇的城镇土地集约利用水平划分为四个级别,并以ARCGIS9.0为技术平台,分析区内城镇土地集约利用水平的空间格局,结果表明:区内城镇土地集约利用水平的变化趋向在西南——东北方向上为最大,与之相反的方向为变化最平缓的方向;重心位于渝北区西南方;MoranI为0.13,各乡镇土地集约利用趋向聚集,但聚集程度不强。

重庆市万州区城市土地集约利用研究

结合重庆市万州区实际情况,选取分析指标,建立城市土地集约利用评价指标体系,对万州区城市土地集约利用程度进行了评价;同时从全国筛选出9个规模、人口与万州区相近的城市,进行了比较研究。
