基于GIS的丹阳城镇工程建设适宜性评价
|
摘要
为了使城市地质调查成果更好地服务于新型城镇化建设,以正在开展的丹阳城市地质调查项目为依托,分析丹阳市地质环境条件并评价城镇工程建设的适宜性。选取地形地貌、水文、工程地质、水文地质、地质灾害、活动断裂和地震效应7个一级评价因子,地貌分区、水系水域、洪水淹没程度等11个二级评价因子,以500 m×500 m网格为评价单元,利用GIS软件对丹阳市进行工程建设适宜性评价。在此基础上,叠加了丹阳市生态红线管控区,将一级管控区划为工程建设不适宜区,二级管控区划为工程建设适宜性差区。结果表明,除生态管控区外,丹阳市工程建设适宜性总体良好,大部分地区为适宜区,适宜工程建设;城市开发建设不能突破生态保护红线。
In order to better apply of urban geological survey results in the construction of new-type urbanization,an urban geological survey project was carried out in the city of Danyang to analyze its geological environment conditions. Seven first-order evaluation factors( such as topography,hydrology,engineering geology,hydrogeology,geological disaster,active fault and seismic effect),and 11 second-order evaluation factors( such as topographic division,waters system and flood inundating level) were selected to involve in this evaluation. Through GIS software,the suitability of engineering construction in Dangyang city was evaluated on a grid of 500 m×500 m. The ecological redline control area in Danyang was superimposed on the evalutation results. This study divided Dangyang into two areas: the first-level control area was defined as the unsuitable area for engineering construction and the second-level control area as the poor area for engineering construction. The results show that,except for the ecological control areas,Danyang enjoys a good suitability of engineering construction,with most of the area well suitable for engineering construction,but urban development and construction must not break through the redline of ecological protection.
