Geological Environmental Adaptability of Qingdao Rural Urbanization Based on Fuzzy Mathematical Method

Fuzzy mathematics comprehensive evaluation method is used to evaluate the geological environment suitability of rural urbanization in Qingdao City, China. A total of 5 first-level evaluation factors are selected, including environmental geological condition, geological resources, engineering geological condition, geological disaster and environmental geological problem, and human engineering activity. And there are 27 second-level evaluation factors, such as topography, land type and vegetation, nature reserve, water source protection area, groundwater quality division, and major engineering project. Qingdao City is divided into four districts of suitable area, relatively suitable area, moderately suitable area and relatively unsuitable area of ecological environment. And their characteristics are introduced. Suggestions for the developing direction of urban construction are put forward. Region of Laoshan District lying to the west of the Shilaoren is suitable to set up high-rise building; west Hongshiya may establish a waste landfill site; Jiaozhou Bay, the downstream of Dagu River, and Jihongtan Reservoir should be built as the key geological environment protection area and water source protection area. And the north Hongdao should be strictly monitored in order to control the expansion of urban construction to Jihongtan Reservoir. Mocheng District and the area north of it, Jiaozhou District and the area east of it are the ideal urban construction development areas in Qingdao City in the future.
