城市建设用地地质环境适宜性评价

城市建设用地地质环境适宜性评价是在城市远期规划的基础上，从地学的角度出发，综合考虑各种影响因子的影响，对城市远期规划建设用地地质环境适宜性进行综合评价，为城市远期规划用地提供依据。基于汝州市城市地质调查工作区范围，对评价区进行评价单元划分，根据自然地理条件、水文地质条件、工程地质条件、环境地质条件和社会影响条件5大类评价因子的影响，采用层次分析的方法，得到汝州市城市建设地质环境适宜性评价分区。研究为城市资源、环境、生态合理开发利用与保护提供地学依据。

Geological environmental suitability evaluation of urban construction land

The evaluation of the geological environmental suitability of urban construction land is based on the long-term urban planning，starting from the perspective of geosciences，comprehensively considering the influence of various influencing factors，and comprehensively evaluating the geological environmental suitability of the urban long-term planning construction land.Provide basis for long-term planning of land use.Based on the scope of the urban geological survey work area in Ruzhou，this paper divides the evaluation unit of the evaluation area.According to the impact of five categories of evaluation factors:natural geographic conditions，hydrogeological conditions，engineering geological conditions，environmental geological conditions and social impact conditions，with the method of analytic hierarchy process，the suitability evaluation zone of the geological environment for urban construction in Ruzhou is obtained.Research provides a geological basis for the rational development，utilization and protection of urban resources，environment and ecology.
