Evaluation Of Eco-geological Environment In Shijiazhuang City

With the development of geological research,more and more attention about the combination of geological environment and ecological environment is paid by scholars.This study covers the center and the surrounding areas of Shijiazhuang City With a total area of about 1945.68 km2.As the capital of Hebei Province,Shijiazhuang City is the political,economic,cultural and scientific center as well as a major industrial concentration.With the traffic developed,Shijiazhuang city is the main hub of the national railway transportation.In recent years,with the rapid development of economic and the increasing population,The increasing demand for resources and the unreasonable development and utilization of resources lead to the increasing pressure of geo-ecological environment and continuous deterioration of ecological environment.These problems have seriously restricted the Economic Sustainable Development of Shijiazhuang City.This study is focused on the evaluation of the geological environmental factors and the ecological environment factors.With a full analysis of the geological environment and the ecological environment conditions,The study area is divided into two evaluation units,the low tilt piedmont plain and the hilly mountain.Evaluation index system is established for the different units,and AHP is chosen to get the weight of each index factor.Then evaluate the geological environment and the ecological environment.Analyze the results of the evaluation,and try to find the main factors.By researching and evaluating Shijiazhuang of the geo-ecological environment,we can fully understand the geo-ecological environment problem in Shijiazhuang city and surrounding areas,such as occurrence,development,variation and hazards of the problems.And then put forward the prevention and control measures and reasonable proposals to various types of geo-ecological environment problems to provide the basis of geological evidence for management.According to the results of the evaluation:the quality of geo-ecological environment in the low tilt piedmont plain is general level,and the main factors are groundwater and human activities,the quality of geo-ecological environment in the hilly mountain is general-good level,and the main factors are geological disasters and mining.At last,according to the results,combined with government plans,research area is divided into two regions and eight sub-regions,and then appropriate protection and prevention recommendations,are proposed to deal with the geo-ecological environment problems of each region.
