摘要
目的祁东矿是淮北煤田的大型煤矿之一,近年来,随着对矿区煤炭资源的持续开发,矿区引发了一系列生态环境问题。通过调查矿区的生态环境状况指数,了解矿区生态环境现状,为矿区环境治理提供决策。方法运用RS和GIS技术与数理统计方法,将宿州市祁东矿区土地利用/覆盖类型分为10类,并进行遥感影像解译,统计矿区土地利用/覆盖类型现状;以生物丰度指数、植被覆盖指数、水网密度指数、土地胁迫指数、污染负荷指数为指标,对宿州市祁东矿区生态环境进行评价。结果 2015年评价区内的主要土地利用/覆盖类型为耕地和居民建设用地,两者之和占总矿区面积的84.50%,宿州市祁东矿区生态环境状况指数为61.75,生态环境等级为良,说明祁东矿区植被覆盖度较高、生物多样性较丰富、适合人类生活。结论运用这种方法对矿区环境进行长时间的监测和评价,观察矿区生态环境变化,可为矿区环境治理提供依据。
Objective Qidong coal mine is one of the large coal mines of Huaibei coalfield.In recent years,with the continuous development of coal resources,the mining area has caused a series of problems of ecological environment.By the ecological environment indices of the mining area,the current situation of ecological environment in the mining area was obtained and suggestions for decision-making were provide for mine environment control.Methods RS and GIS technology and mathematical statistics methods were used to divide the land use/land cover types in Suzhou Qidong mining area into 10 categories.And they were interpreted by remote sensing images.And the statistics of current mining area land use/land cover types were conducted.Based on biological richness index,vegetation coverage index,water network denseness index,land stress index and pollution load index,ecological environment of Qidong mining area was evaluated.Results In 2015,the main use/cover types in the land evaluation area were farmland and urban construction land,accounting for 84.50% of the total mining area,and ecological environment grades in Qidong mine area was good with ecological index at 61.75.That showed that in Qidong mine area had higher vegetation coverage and richer biological diversity,suitable for human life.Conclusion Using this method to monitor and evaluate the mine environment for a long time,and observing the changes of the ecological environment in the mining area can provide a basis for controlling the environment in the mining area.
