Suitability evaluation of land space development in Taizhou based on urban geological survey results

The suitability evaluation of land space development is the basis of land space planning, which is of great significance to urban sustainable development. Based on the geological survey achievements of Taizhou and the city development planning, the authors in this paper have fully analyzed the geological resources properties, geological environment security, ecological sensitivity and underground space development suitability. Besides, the evaluation index system of land space development suitability was built and the indexes affecting the suitability were divided into two categories of the restricted and the non-restricted. Compared with the urban space planning, the suitability evaluation of land space development for Taizhou was conducted, and different management measures for different suitable areas in urban space and agricultural space were put forward. The results show that the urban space pattern optimization must be based on the geological resources guarantee and geological environmental security analysis. The suitability evaluation of land space development is the refinement and promotion of urban geological survey results and also the concrete embodiment of the urban geological survey which serves the land space planning.
