基于专家–层次分析定权法的日照国际海洋城生态地质环境综合评价
Comprehensive Evaluation of Eco-Geological Environment of Rizhao International Ocean City Based on Expert-Hierarchical Analysis Weighting Method

本次结合日照国际海洋城的生态地质环境特征，应用专家–层次分析定权法并选取基础地质条件、工程地质条件、地质环境问题、地质资源等4个地质环境对其地质环境进行综合评价研究。研究结果显示调查区域存在：植被覆盖率较高，地下水质量良好，地质灾害不发育的生态地质环境质量优区(I)，面积约35 km2；植被覆盖率较高，地下水质量较好，地质灾害不发育的生态地质环境质量良好区(II)，面积约35 km2；植被覆盖率中等，地下水质量一般，地质灾害不发育的生态地质环境质量一般区(III)，面积约10 km2；植被覆盖率较低，沿海地区地下水质量较差，易发生地质灾害的生态地质环境质量较差区(IV)，面积约70 km2。这不仅仅对日照国际海洋城的生态地质环境进行了综合评价，而且为其建设发展提供了科学依据，具有重要的实践价值。
Based on the characteristics of Rizhao International Ocean City’s eco-geological environment, this paper applies expert-hierarchical analysis weighting method and chooses four geological environments, including basic geological conditions, engineering geological conditions, geological environmental problems and geological resources, to make a comprehensive evaluation of its geological environment. The results show that there are: High vegetation coverage, good groundwater quality, good eco-geological environment quality area with undeveloped geological hazards (I), about 35 km2; high vegetation coverage, good groundwater quality and undeveloped geological hazards eco-geological environment quality area (II), about 35 km2; medium vegetation coverage, general groundwater quality and undeveloped eco-geological environmental quality area (III), with an area of about 10 km2; low vegetation coverage, poor groundwater quality in coastal areas, and eco-geological environmental quality area prone to geological disasters (IV), with an area of about 70 km2. This paper not only comprehensively evaluates the eco-geological environment of Rizhao International Ocean City, but also provides a scientific basis for its construction and development, which has important practical value.
