The Complex Structure Of Geological Environmental Assessment Of Remote Sensing Technology Applications

Since last century, people do the more and more intervention to the environment with the exaltation of the populations and the productivity. It exceeds the evolvement of the natural environment to the lithosphere system .So the geologic disaster takes place again and again .Hence , on the foundation of the ecosystem environment, the experts put forward the concept of the environment geology , the geology environment and the geology environment evaluation .The research object of the environment geology means the correlation between people and the earth .It involves abundant contents .Time and space is dominant and it is not suit to the traditional geology methods .The quick development of remote sensing technique provides the research of the environment geology strong tools. Particularly remote sensing is macroscopically, highly spectral and multi-temporal, so it not only can investigate quickly and monitor dynamically, but also can subdivide the geology phenomenon. The remote sensing technique must be important to improve the level of environment geology research. Nowadays the remote sensing technology development has created multi-platform, multi-band, high-resolution observation of the Earth continuous large information systems. It will be in a very short time to repeat the change information of the same area so as to enable environmental geology research be possible. Some international developed countries have mad; many achievements in environmental geological investigation and evaluation application of remote sensing technology. It contributes to various environmental geological problems.Using the example of the Dabao express highway in Yunnan the paper introduces the application remote sensing technology in complex geological formations district environmental evaluation. The article firstly introduced related principles and methods of geological environmental assessment system , and then identify the factors and the scope of the geological environmental evaluation factors .We firstly collect remote sensing image data, Dem data, topographic maps, geological data of the Dabao express highway in Yunnan .So we extracts the geological formations message .At last we evaluate the actuality .forecast ,layout of the geological environmental using complex of the multi resource remote sensing geological information. Finally we clean up the result of the dealing with remote sensing imagine and analyses the corresponding reasons and give some suggestions.The development of the geological environment evaluation system is not still mature in the our country , but it has already become the very important part in environmentevaluation .This paper expatiates the meaning of the geological environment comparing the ecological environment, and it researches the methods and the technique routes of the geology environment evaluation consulting the 3S technique. It offers professional supports and direction to the work of environment evaluation.
