基于RS和GIS的秦岭金钱河流域露天采掘场监测研究

流域是人类活动对生态环境影响的重要监测项目。应用RS与GIS技术,对陕西省内秦岭金钱河流域露天采掘场进行动态监测,得到2007、2009和2011年3期露天采掘场开发现状数据,在此基础上,对比分析近五年来露天采掘场的变化情况,统计出露天采掘场逐年的数量和面积变化。结果表明,近五年来该流域区露天采掘场数量和面积都在逐年增加,但2009~2011年与2007~2009年相比增幅减小,说明金钱河流域露天采掘场开发活动得到了整治,生态环境质量逐渐改善。

Research on the Dynamic Change of the Openwork in the Jinqian River Basin of Qinling with RS and GIS Technology

Basin is important to monitor the scale of human activities on affecting Affect the ecological environment, It is obtained of three openwork development status data in 2007, 2009 and 2011by researching on the dynamic change of the openwork in the Jinqian river basin of Shaanxi Qinling using RS and GIS technology.On this basis, the paper compares and analyzes the changes of openwork in nearly five years, a statistical data about the number and area changes of openwork year by year that is counted.The results showed that the number and area of openwork are increasing year by year in the basin, but the increase amplitude is gradually decreased com-pare 2009~2011 with 2007~2009, which indicated that the openwork development activities and the environment quality of Jinqian river basin have gradually improved.
