摘要
根据生态压力对环境状态的影响,以及人类社会应对环境危机做出的响应,以数理统计方法和地理信息技术为支撑,依据PSR模型构建了兖州矿区生态评价指标体系,并对矿区做出生态安全评价。同时,根据自然环境与生态环境的内在联系,使用遥感作为环境监测的技术手段,对矿区的生态安全进行监测分析。评价的综合结果表明该地区生态系统服务功能已经退化,生态环境遭受一定破坏,生态结构发生很大变化,客观反映了兖州矿区的生态问题和安全现状。
According to influence of the ecological pressure on the environment and the human community＇s response to the environmental crisis,this paper constructed ecological evaluation index system of Yanzhou mining area and evaluated the current ecological status of the area based on PSR model using mathematical statistical method and geographical information technology.Meanwhile the paper used remote sensing technology as a monitoring method to analyze the ecological security of the mining area according to the interrelationship between the natural environment and ecological environment.The comprehensive result showed that the ecosystem service function had already retrogressed,the ecological environment had suffered certain damages,the ecological structure had a great change,and objectively reflected the ecological problems and security status of Yanzhou mining area.
