Study, Based On 3s Technology Mountain Road Along The Eco-environmental Information Management System

Yunnan province lies in the plateau of Yun-Gui and is a plateau mountain area. Its physical geography is special, the topography rises and falls enormously, the ground form is extremely broken, the ecosystem is various , complicated , fragile.At present, with the large development of western regions , " China- the construction of ASEAN Free Trade Area ", " Lancang River - Mekong River sub-region economic cooperation ", and great development of strategy of Yunnan Province international large passway building strategy,Basic construction of facilities of serial great traffic, especially the construction and operation of the expressway of mountain region will make the ecological environment system of the whole province receive the lasting and extensive perturbation and is in changing period fastUtilizing 3S (GIS , GPS , RS ) technology along the line of launching the mountain region highway of Yunnan, ecological environment research is very urgent.GIS is for using the space information system set up of the goal specifically , is it deal with , input , store , inquire about , search , analyse , show , upgrade and offer the technological system used to go on to relevant space data.GPS if a new generation space satellite navigate navigation system, main purpose is to offer real-time , all-weather and global navigation service for land , sea , empty three major fields.RS is under the condition that do not contact directly , a kind of technology surveyed and perceiving to the goal or the natural phenomena remotely.At present, at home and abroad, 3S (GIS , GPS , RS ) Technology is in the planning of highways, feasibility research, route scheme select, for more application road construction , especially expressway tunnel and planning and construction aspect of bridge.But the application and studying also more deficient in ecological environment along the line of the highway of mountain region of 3S technology.So, this dissertation analyses the impact on ecological environment of road construction scientifically through the application of 3S technology, There are important social realistic meanings to the highway way land ecological environmental protection of mountain region in the information management system of the ecological environment along the line of researching and developing the highway of mountain region based on 3S technology.The dissertation sets up the information management system of the ecological environment along the line of the highway of mountain region by means of 3S technology, studies primarily in development of ESRI MapObjects and application in the ecologicalenvironment system in the highway. Combining the advantages of developing language Visual Basic 6.0, ESRI MapObjects and database platform SQL Server2000 ,the dissertation carrys on the construction of the information management system of the ecological environment along the line of the highway of mountain region .The system developed has been realized routine GIS functions of various kinds of thematic maps such as the display of the map, enlarges , dwindles , roams , hawk's eyes , adding the highway , river system , vegetation ,etc.Including collection,deletion and edition of map meta information Realizing the function of layer information of maps statistics and querying. In the subject highway of Yunnan, according to the characteristics of different highways, through surveying and studying and analysing, choose Kunming -The stone forest expressway to carry on analysis and application study on function damaged ecological environment information of the view especially;Choose Dali -The expressway of Baoshan to carry on analysis and application study on natural calamity ecological environment information in the mountain region especially; And choose Simao -Small Meng raises the expressway to carry on analysis and application study on ecological environment protection information of bio-diversity especially. In natural calamity of mountain region along the line of the highway of mountain region, study GPS technology realtime application and afterwards monitor in such characteristic ground things as the slope , bridge and tunnel ,etc.
