汾河流域生态地质环境的区划与评价

Fenhe River Basin Eco-geological Environment Revitalization and Evaluation

受频繁的人类活动和脆弱的生态地质环境的影响,近年来,山西汾河流域的生态地质环境急剧恶化,对流域经济发展已构成严重威胁.土壤盐渍化、水资源紧缺、地下水质污染、地下水降落漏斗和地面沉降等地质环境问题普遍存在,土壤沼泽化和沙化也正在发展蔓延.为了遏制生态地质环境质量急剧恶化势头,促进山西经济、资源与生态地质环境的协调发展,本文通过建立汾河地质环境评价的指标体系,采用层次分析数学模型和生态地质环境质量综合指数评价方法,将山西汾河流域生态地质环境划分为3个大区,28个亚区,并系统分析了汾河流域28个亚区生态地质环境特征,揭示了影响可持续发展的生态地质环境问题.

In recent years,the Shanxi Fenhe River basin Eco-geological environment has some rapid deterioration deteriorated and the basin economic development has been a serious threat by the multifarious human activities and fragile Eco-geological environment. Soil salinization,the shortage of water resources,underground water pollution and groundwater funnel and groundwater draw down cone are widespread,the soil swamping and desertification are spreading widely. To control Eco-geological environment deterioration,and promote the shanxi economy,resources,and the coordinated development. The Eco-geological environment of Shanxi Fenhe River Basin was divided into 3 regions,28 sub-region systematic,analyzed the 28 sub-region,system analyzed Eco-geological environment characteristics and revealed Eco-geological environment problems which influenced the sustainable development through the established of Shanxi Fenhe River basin geological environment evaluation index system,and used hierarchical analysis mathematical model and the ecological geological environmental quality comprehensive index evaluation method.
