锦州市规划区地质环境安全评价研究

地质环境问题是影响城市国土空间安全开发利用的重要因素，在城市规划开发阶段开展地质环境综合评价可有效控制地质灾害风险。锦州市规划区尚处于开发前期，本文基于该规划区的地质条件和开发需求，构建了地质环境安全评价指标和评价方法体系，基于主导因素综合法开展了地质环境安全综合评价。根据评价结果，锦州市规划区地质环境安全程度可划分为3级，空间分布上以相对安全区为主，其次为次不安全区和安全区。按照空间位置和区域构造稳定性、地质灾害易发性等不同成因划分为23个亚区，并指出了每个亚区安全程度主要影响因素。该评价结果反映了锦州市规划区的地质环境安全程度，确定了影响地质环境安全问题的关键因素，有助于规避该区国土空间规划开发可能面临的地质灾害风险。

Evaluation on the safety of geological environment in the planning area of Jinzhou City

Geological environment is crucial for the safe development and utilization of urban land space, and a comprehensive evaluation of geological environment in the urban planning and development stage will aid to control the risk of geological disasters. This work took the planning area of Jinzhou City as an example, which is still in the pre-development stage. Based on the geological conditions and development needs, this study established a system of geological environment safety evaluation indexes and evaluation methods, and comprehensively evaluated the geological environment safety based on the dominant factor synthesis method. The evaluation suggests that the geological environmental safety in the study area can be divided into three levels, which are dominated by relative safety zone, followed by secondary unsafe zone and safety zone. In addition, the three zones were subdivided into 23 sub-zones according to the spatial location, regional tectonic stability and susceptibility to geological hazards, and the main influencing factors of the sub-zones were determined. The evaluation can well reflect the geological environmental safety and illustrate the key influencing factors, which will help to avoid geological hazards in the development of land space planning in the region.
