Pearl River Source Nanpanjiang River Valley Environmental Information System For The Proposed Research

There are many tourism resources in the nature reserve region, Pearl River source Nanpanjiang is located in the East Yunnan plateau of the northern part of a special landscape, located in the northeast of Yunnan clay plateau tourism which in the Six Area Tourism in Yunnan Province.There are mainly Sedimentary rocks in the region of study. Karst topography is very rich, Pleasant weather. There are Pearl River source of rich natural tourist resources and Ma Hung-shan which famous of it's Majestic and flowers Lake which famous of it's strange. Now, it as a state-level forest parks and scenic spots in Yunnan province. At the same time, as the Pearl River source region's economic development earlier, and the study area densely populated, high-intensity of human activities, caused the ecological environment serious damage in the region. The ecological and geological environment is becoming worse, the basin is facing a low forest cover, increased soil erosion, land desertification of the grim situation.Karst mountain watershed is a basic geographical units or geographical system. The forest, grassland, farmland, villages, towns and other subsystems in the System are interrelated and mutual restraint. Once the destruction of the ecological geological environment will be difficult to restore, how in the development of the region with the resources to meet the travel needs of tourists with each passing day of the study area without undermining the fragile ecological geological environment as a much-needed resolve. Therefore, these areas of tourism development in the region must be based on the current situation and the natural ecological environment, socio-economic conditions, a systematic, scientific unified planning.This paper to write on the based component of GIS- the regional tourism development of environmental information system for the exploratory study, for the regional tourism environment, including ecological and geological environment of the study and explore a new way. At present, based on the component GIS has been used in many fields, but few in our country to see their tourism in karst areas of environmental information. In the geographic information system development and current research focus on the basis of geology ,from the perspective of the tourism resources of the study area, while more attention to information on the ecological and geological environment area, collected a wide range of information. Application of geology, tourism, science, geomorphology, and other multi-disciplinary knowledge and experience, after made a comprehensive analysis of the data, use of geographic information systems, remote sensing technology for the source of the Pearl River Basin Nanpan river the regional geological environment information, tourism information and human activity Extraction; Including for water systems, remote sensing interpretation of the geological structure and thematic maps of the buffer zone analysis to the study area. The tourism resources are breakdowned in a reasonable space on the geographical. Finally, on the ESRI's GIS software component MapObjects2.4 platform and Microsoft's visual development platform Visual Basic6.0, implementation of the Pearl River source Nanpanjiang River Tourism Environment Information System Construction for landscape protection and sustainable development to provide a scientific basis.
