生态地质作为一门新兴交叉学科,诸多学者对其研究内容、工作思路、技术手段、服务目标等进行了探索.以京西"一线四矿"为研究对象,阐述了以服务于生态保护和修复为目标的生态地质调查总体思路和工作方法,建立了生态地质分区评价指标体系.研究结果表明:生态地质分区评价能够直观反映生态地质本底特征,是生态地质条件优劣的直接表现;"地理+地质+生态"三要素融合的生态地质分区评价模式,建立了1个目标层、3个准则层、10个指标层的评价指标体系,其中地理环境权重0.1226,地质环境权重0.6011,生态环境权重0.2763.以地质建造为分类单元,地表基质层支撑力由强到弱分别是中性侵入岩建造、陆源碎屑岩建造、中性喷出岩建造、基性喷出岩建造、碳酸盐岩建造.京西"一线四矿"地区(287 km2)生态地质条件良好区面积105.9 km2,占比36.9％;一般区面积78.7 km2,占比27.4％;较差区面积102.4 km2,占比35.7％.在京西"一线四矿"及周边区域协同发展概念规划总体策划范围(99 km2),圈定出乔木生长适宜区面积58.6 km2,灌木生长适宜区面积40.4 km2.
Research on ecological geological survey methods and evaluation system——a case study of "One Line and Four Mines" area in western Beijing
Ecological geology is an emerging interdisciplinary field. Many scholars have explored its research content, work ideas, technical means, and service objectives. Taking the "One Line and Four Mines" area in western Beijing as the research ob-ject, this paper elaborates on the overall idea and working methods of ecological geological survey with the goal of serving eco-logical protection and restoration, and establishes an ecological geological zoning evaluation index system. The research results show that the evaluation of ecological geological zoning can directly reflect the background characteristics of ecological geology and is a direct manifestation of the advantages and disadvantages of ecological geological conditions. This paper proposes an eco-logical geological zoning evaluation model using the "geography+geology+ecology" method, and establishes an evaluation index system consisting of 1 target layer, 3 criteria layers, and 10 indicator layers. The weight of the geographical environment is 0.1226, the weight of the geological environment is 0.6011, and the weight of the ecological environment is 0.2763. Taking geo-logical formation as the classification unit, the supporting force of surface matrix layer from strong to weak is neutral intrusive rock formation, terrigenous clastic rock formation, neutral volcanic rock formation, basic volcanic rock formation and carbonate rock formation. The area with good ecological and geological conditions in the "One Line and Four Mines" area of western Bei-jing (287 km2) is 105.9 km2, accounting for 36.9％. The general area is 78.7 km2, accounting for 27.4％. The area of the poor area is 102.4 km2, accounting for 35.7％. In the overall planning scope of the concept plan for coordinated development of the "One Line and Four Mines" and surrounding areas in western Beijing (99 km2), the suitable area for tree growth is delineated as 58.6 km2, and the suitable area for shrub growth is 40.4 km2.
