Study On Monitoring Of Mine Ecological Environment Based On RS, GIS&GPS

The mineral resource is important material base for the humanity livelihood and the development .But since long ago, in the process of exploit mineral resource,because of limitation of cognition, many mines in our country neglect the environmental protection work in the mineral resource development and use. So it destroies the ecological environment of mining area seriously. The environmental problems has become one of focal points which the various countries most pays attention now.Then, Carrying on the effective monitor to the environment's present situation and the change is general trend of events. Using the 3S technology can withdraw the mine ecological environment information real-time and conveniently. It can provide the important basis for the people to understand the environment present situation information and the development evolution rule comprehensively , use the land reasonably and restores the government environment.In this article,the author uses the Quickbird image in January of 2006 and the correlation statistical data, selects the man-machine interaction interpretation method to extract land utilization/covering information, geological disaster and the environmental pollution because of the mine mining, as well as restoring and government the mine ecological environment information in Panzhihua Baoding coal mine area. This article,based on the AHP method, takes the vegetation coverage fraction, the environmental pollution rate, the geological disaster area ratio and the environment restores rate as the appraisal factors, carries on the appraisal and the analysis to ecological environment quality in the Panzhihua Baoding coal mine area, and gives the measure and suggestion to treatment of environment.Its major research contents are as follows:(1) Remote sensing digital image processing. Including orthographic projection , geometric correction, image fusion and image enhancement. (2) Extracting remote sensing image information. It selects the man-machine interaction interpretation method to extract land utilization/covering information, geological disaster and the environmental pollution because of the mine mining, as well as restoring and governmenting the mine ecological environment information in Panzhihua Baoding coal mine area of the year 2005.(3) Database building of the mine area environment. Including metadata, mine mining condition interpretation data, mine environment condition interpretation data and so on.(4)Thematic mapping of remote sensing images. Including 1:1 million land use / cover map,the ecological environment Remote monitoring map of Baoding coal mining area and so on.(5) Field data verification. Through field investigation,we can contact the objectives on remote sensing images to features of the actual to verify the accuracy of information extraction interior for future interpretation of job experience.(6) The ecological environment monitoring and quality evaluation in mine area. Selecting evaluation indicators, setting up an appropriate evaluation model for the eco-environmental quality evaluation of study area .Conclusion as follows:(1)In 2005 the land use / cover the situation of study area is that forest land area ,including forest, shrub forest and woodland land, is the largest for xxxx.34 hm2, accounting for the total area of the study area xx.87%; Grassland area is xxx.386 hm2, accounting for the total area of the study area x.91%; Dryland area is xxx.445 hm2, accounting for the total area of the study area x.78%; Dump is also quite a number, there is perhaps xxx.351 hm2, accounting for the total area of the study area x.22%.(2)It results from the ecological environment monitoring and analysis that, in the Panzhihua Baoding coal mine area, the air pollution area is xx.59hm2 and the water pollution area is x.84 hm2,the dust pollution area is xxx.17hm2 and the ecology restores area is x.53hm2 and there had been 13 latent landslides,4 mud-rock flows,11 cave-ins.(3) Using remote sensing and GIS technologies based on APH method to evaluate the environmental quality of Panzhihua Baoding coal mine area. It concludes that the vegetation coverage of the area is good for levelâ…¡; environmental pollution is serious for levelâ…£;the mine e environment restore rate is not high for levelâ…¢; the disasters incidence is also not high for Levelâ…¡.The general quality evaluation of the ecological Environment in study area is levelâ…¢. Practice has proved that using the 3S technology to monitor the land ues /cover and ecological environment , evaluate and analysis the ecological quality of coal mine area can provide a scientific basis for the sustainable development of mineral resources, and while provides an effective and feasible technology flow and ideas for other types of mine the ecological environment monitoring study.
