Investigating And Evaluating Of Tourism Resources Based On GIS

With abundant species resources and steady forest ecosystem, Tangjiahe Natural Nature Reserve in northwest of Qingchuan, Guangyuan, has been assessed A Reserve by World Wildlife Fund because of high conservation and scientific research and eco-tourism value. At present, Tangjiahe Nature Reserve is planning and exploiting of eco-tourism in order to construct "Yellowstone National Park of China".Traditionally, there are constant forms such as fieldwork and surveying on the spot in tourism resources investigation. These are all described by hand which includes the collection and compilation of tourism resource information and map plotting and resource evaluation. The course of tourism resource investigation and evaluation is much more trouble for Tangjiahe Nature Reserve with higher vegetation overcast and up-and-down landform. With the technology development of computer and GIS and application deeply, tourism resource investigation can make use of RS and GPS to achieve high-speedly and save and inquire about and analyze all information including of numbers and letters and pictures.Based on comprehending sufficiently the information of Tangjiahe, RS and GIS as accessional measure, It is exerted in tourism resource investigation and evaluation of Tangjiahe National Nature Reserve. The productions are achieved in the process of applied research such as:l)Build up three-dimensional model by disposed RS image to show landform and physiognomy visually, and make out some RS geological interpretation.2)Compile special and pretty thematic map.3)Build up database, manage information and realize information inquiring and showing expediently.
