Based On Rs And Gis In Yanqing County Tourism Eco-environmental Quality Evaluation

Tour environment is the basic for developing of tourism. Nowadays, the tourists give more attention to eco-environmental. It is the theoretical basis of remaining and improving regional eco-environmental quality to evaluate situation of eco-environment state. Tourism is the supporting industry for Yanqing County, it is the newer tour item and increase points of economy. So, it is important to evaluate the eco-environment for Yanqing's continuable development.With RS&GIS and some relevant theories, the author establish tourism eco-environmental quality evaluation system of Yanqing County, then use principal component analyse (PCA) method to evaluate the tourism eco-environment, and nalyze the influence of land use change on eco-environment. At last, give the suggestion for protect eco-environmental of Yanqing County.4.Main achievements and innovations in this paper are as flows:1. Tourism eco-environmental quality evaluation system of Yanqing was established. Existing evaluation are simple describe mostly, so the evaluation system settle basic for further research.2. Using principal component analysis (PCA) method to evaluate the tourism eco-environment of Yanqing County, tourism eco-environmental quality evaluation rank map was made, and analyze the influence of land use change on eco-environment.3. Using the method of multi-subject spatial data, it can comprehensively understand the general characteristics and the regional difference of Yanqing County tourism eco-environmental. Using the numerical analytical method, the regional quality of tourism eco-environmental was contrasted. The form of spatial data was used in the research. Form the data collection to result analysis, the information spatial position character was kept all the time. So we can know the difference of data and analyse spatial distributed regular. The calculation result is visible so as to heighten the function of achievement. The utility of RS enhances the precision of the achievement.4. The research serves the Yanqing's continuable development of tourism. Meanwhile, the methods of evalution and data disposal are fit to evaluate other regions in some extend, and they can also be use for reference to homogeneous research.
