半干旱地区城市用地生态适宜性评价——以呼和浩特市为例

摘要/Abstract

摘要： 对区域非城镇建设用地用作城镇建设用地的生态适宜程度进行评价是城市生态规划的核心问题,也是城市总体规划制定的基础和依据。以呼和浩特市为例,采用单因子评价分析与综合评价分析相结合的方法,在ArcGIS软件的空间分析功能的支持下,确定了呼和浩特市城镇建设用地适宜、较适宜、较不适宜和不适宜4级综合生态适宜性分类。研究结果表明,呼和浩特市城镇建设用地适宜级别土地占总面积的39.1％;较适宜级别占7.3%;较不适宜级别占25.6%;不适宜占28.1%。从不同适宜级别土地在不同旗县区的分布特点来看,呼和浩特市城区、土默特左旗的适宜建设土地相对较多,分别为39.1%和28.5%;土默特左旗和托克托县的不适宜土地相对面积较大,分别为45.3%和53.6%。

Abstract: The analysis of the ecological suitability assessment for un-urban area transferring to urban construction land was not only the major problem of urban ecological planning, but also the foundation and basis of the constitution of general urban planning. Taking Hohhot City as a case study, the analysis of single factor assessment and integrated assessment for the urban construction land have been used to study the comprehensive ecological suitability of un-urban area transferring to urban construction land based on the spatial analysis function of ArcGIS software, confirming the following four comprehensive ecological suitability categories, i.e. suitable, sub-suitable, little unsuitable, and unsuitable land. Findings showed that the suitable land area occupied 39.1% of the total area; the sub-suitable land, 7.3%; little unsuitable land, 25.6%; the unsuitable area, 28.1% for the urban construction land in Hohhot City, respectively. According to the characteristics of different ecological suitability types in different counties (banner or districts), Hohhot urban districts and Tumotezuo banner had higher suitable land area than the others as 39.1% and 28.5% respectively, and Tumotezuo banner and Tuoketuo county had higher un-suitable area than the rest as 45.3% and 53.6% respectively.
