GIS method and its application for harmonious evaluation of urban construction land and geological environment

Abstract

In order to better plan urban construction land, improve the efficiency of urban land use, and reduce the loss of people’s lives and property caused by geological disasters, from the point of view of regional coordinated development, considering the geological environment assessment and land use types of planning areas, geographic information technology (GIS) is used in this study to reveal the coupling and coordination relationship between urban construction land and geological environment; and reasonable urban land use planning proposals are put forward. Through comprehensive analysis, urban planning land types are classified into four categories, which are residential and public facilities land, industrial and warehousing logistics land, supporting functional land, and ecological greening land. According to the requirements of various types of urban planning land for the quality of geological environment, and combined with the results of the coordinated zoning of urban construction geological environment, the corresponding urban construction suggestions are put forward respectively for the highly coordinated area, the basic coordinated area, the slightly imbalanced area, and the seriously imbalanced area of urban construction land and geological environment. Therefore, this study provides a scientific basis for the planning and layout, land use, disaster prevention, and mitigation of various cities in China, and is of great significance to the progress of urbanization in China.
