Preliminary Study On The Problems Of Mine Geo-ecological Environment In Gansu Province

Aim at the disaster exist in mine geological and ecological environment in Gansu, this paper systematically discuss its features, hazards and influencing factors, explore the treatment model which will help government departments charged with the overall situation, focuses on major stages, carry out integrated planning management in groups and restore mine geology ecological environment. It'll be great realistic and far-reaching historical significance to mine geo-ecological environmental protection, disaster prevention and sustainable economic and social development.From the study situation of domestic and abroad geological and ecological environment quality division, analyze the development trend of geo-ecological environment problem through analyzing the main problems found in this study. In detail, this study research in the following three aspect: mine geo-ecological environment and community economy general situation, mine exploitation and utilization statu in quo and the mine geo-ecological environment, through mathematical models such as analytic hierarchy process transform multiple attributes to objective and quantitative evaluation or subjective effects to determine the grade of geological eco-environmental quality. Finally advance the model of governance and recovery to mine geo-ecological environment problem. Concrete results as follows:(1) Based on the actual statistical analysis of survey data, summed up problems in the status quo of mineral resources exploring and utilizing in Gansu Province as well as in mine geo-ecological environment.(2) Through filtrating the the various indicators use arousing geo-ecological environment problem, by means of fuzzy mathematics to establish fuzzy comprehensive evaluation model.(3) According to the actual situation of Gansu Province, applying the established fuzzy evaluation model, use spatial analysis module of MAPGIS6.7 to conduct a comprehensive regional to Gansu Province geological and ecological environment.(4) Comprehensively analysis the disruption and effects of mine exploitation timeslot and mode, human activites to the environment, and advance the model of governance and recovery to mine geo-ecological environment problem.Although the evaluation methods and treatment model obtained from this study are premary, but highly targeted, and will certainly play its due role to mine in Gansu Province as well as the similar geo-ecological environmental protection.
