基于GIS的丹阳城镇工程建设适宜性评价
GIS-based suitability evaluation on constructive lands in the city of Danyang
摘要
Abstract
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.关键词
