| Tourist environment is a special environment system with its own uniqueness. Firstly, it is not only the carrier of tourist resources, but also a kind of important tourist resource itself. Secondly, tourist resources exploration can promote the environmental quality, while it also unavoidably induces destruction and pollution, so it is very important to assess and make a planning about the environmental quality.Based on the sub-program of environmental planning of the tourism development in Taojiang County, the paper aims to provide evidences for vacation village through environmental assessment, especially geological environmental assessment. According to the useful questionnaires of the seven main scenic spot in Taojiang, we think "Meirenwo" is located in TaohuaLake and Xiushan, so the rock, soil and ground water samples of the two regions were collected and were sent to the Isotope Chemistry Study Center Of Guangzhou Institute Of Geochemistry, Chinese academy of Sciences, to analyze trace elements with ICP-MS plasma spectrum instruments. Geological environment assessment was disintegrated for three steps. The first step is element assessment, using necessary elements such as Cu, Zn, Se, Mn and the harmful ones such as Pb, Cd, Hg, As, etc. As to the necessary elements, the parabola assessment is used and the indexes are positive, for harmful ones, "S" curve is used and the indexes are negative. The results show that the necessary elements are higher than the environment background, while the harmful ones are lower. The second step is factor assessment. The.two areas were separated, and the rock, soil and groundwater as a whole were taken as a factor. Then choose average index to assess the geologic environmental quality. The results suggest that geological conditions of TaohuaLake and Xiushan are quite different. The last step is comprehensive assessment, by selecting weighting index toassess the total geologic environmental quality of the two areas. The results point out the index of Xiushan is 1. 213 and Taohuahu is 1.139, that is to say, the geologic environmental quality of Xiushan is better than TaohuaLake.The atmosphere environment used segment index, selected three factors of S02, NOx, TSP, and the highest pollution index represents the environmental quality index. The results indicate the index of S02 is the highest, but the total index is still within the I standard. The specific value assessment is used to the surface water and 13 general indexes (pH, NH3, As, Cr+6, Cd, etc) were chosen. The results manifest the indexes are all qualified of the II standard except for colon bacillus, and the acoustic environment is also qualified. What' s more, the biological resources are abundant and the diversity is also high, therefore the ecologic environmental quality of Taojiang scenic spot is good. Combine the geological environment and ecological environment; consider the humane factor, the "Meirenwo" vacation village should be constructed at Xiushan scenic spot.On the basis of the assessment of present situation of the environment, the paper use tabulation to assess the environmental impact of the pollutants in every scenic spot. The results show that the function and the impact of every scenic spot are different. The highest pollution is in Xiushan scenic spot, and the second is in TaohuaLake, which is in accordance with the function position of the two; The deepest impact of the whole function is the three scenic spot of WumaLake, Fuqiushan and Taojiang county. Analyzed the reasons, we give proposals to guarantee the sustainable utilization of the tourist resources and the sustainable development of regional economy.
