    基于GIS的西咸新区城市建设用地适宜性评价

    THE SUITABILITY EVALUATION OF LAND FOR CONSTRUCTION OF XIXIAN AREA BASED ON MAPGIS TECHNIQUES

    • 摘要: 西咸新区是近年来陕西省实施西咸一体化, 对接西安市和咸阳市的重点建设区域, 总面积882km2, 为西部地区重点建设的5大城市新区之一。虽然西咸新区地理和经济位置卓越, 然而区内地貌单元多样, 地质构造复杂, 地质问题突出, 因此在该新区开展城市地质工作意义重大。在1: 5万工程地质调查基础上, 采用层次分析法构建了西咸新区城市建设用地分区评价指标, 并根据MapGIS分析功能对其进行了适宜性评价。评价结果表明, 西咸新区居住及公共设施用地较适宜区域以适宜、较适宜为主, 占总面积的72.58%, 不适宜区占总面积的22.30%。适宜和较适宜区主要分布在阶地和黄土台塬区, 而不适宜区主要集中在漫滩和高漫滩区, 以及泾河和黄土台塬的接触带, 这些区域因为存在活动断裂、滑坡、砂土液化等地质问题, 因此被评价为不适宜区与实际调查情况相符。

       

      Abstract: With the total area of 882km2, Xixian Area is the key construction projects for Xixian integration in Shaanxi province. Although the Xixian area has obvious advantages of location and economy in west of China, it also is subjected to some risks of geological problems due to complex topography and geological structure. Therefore, it is significant to carry out urban geological research in the study area. As a case study, the suitability evaluation of land for construction of Xixian Area was studied based on the methods of analytic hierarchy process(AHP) and MapGIS.The results show that suitable area for living and public facilities is mainly compose of the most suitable and suitable, accounts for 72.58% of the area, and the unsuitable area takes up 22.30%.The most suitable and suitable areas are mainly distributed on the terrace and loess tableland. While the unsuitable areas are mainly distributed on the flood plain and high flood plain, the contact zones between the Jinghe River and loess tableland. Because of the existing geological problems of active faults, landslide, sand liquefaction in these areas, and it is consistent with the practical survey results.
