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.

Introduction Urban geology is not equivalent to environmental geology. Urban geology refers to various geological elements related to the mutual influence and restriction between human engineering economic activities and geological environment (Daneshvar et al. 2017; Fagbeja et al. 2017). In fact, urban geology is a prominent aspect of environmental geology, and it is the most important aspect of human engineering construction activities. The study of urban geology mainly serves urban construction planning and is a practical geological This article is part of the Topical Collection on Geological Modeling and Geospatial Data Analysis * Guobin Chen [email protected] 1

discipline (Pardo-García and Mérida-Rodríguez 2017). In the 1960s and early 1970s, urban geology began to appear in North America. Since the 1990s, environmental geology in China has begun to consider social and economic factors, and
