The result showed that Taohua Mountain was unique in scenery, rich in rural tourism resources and broad in market prospect. However, the tourism products were monotonous, lack of characteristics and depth; the ecological environment was weak; the tourism staff was with low quality; some parts of the area were in poor sanitary condition, restrained by season and periodicity. Meanwhile, there existed some opportunities and challenges in this park. The opportunities mainly contained policy opportunity and transference of tourists’ preference. The challenges primarily included challenges from urban tourism spots of Ya’an City and surrounding cities, and threats of sustainable use of tourism resources resulting from blind exploitation of fruit production area. And the corresponding development countermeasures were put forward, that is, to develop diversified tourism programs, to allocate mountainous resources according to local conditions, to train the local tourism staff, to dredge the area with poor sanitation, to diversify business with other industries supporting the development of tourism agriculture.展开更多

As, Hg, Cr, Pb, Cd and fluorides in some drinking water sources of Rain City District are analyzed according to Standards For Drinking Wa-ter Quality (GB5749-2006). A health risk assessment model called USEPA is also applied to drinking water health risk assessment and management countermeasure is proposed. The results show that the greatest health risk for individual person per year is caused by Cr(VI). The health risk of carcinogens is much higher than that of non-carcinogens: the greatest risk value due to non-carcinogen pollutants is caused by fluoride (F), achieving 1.05×10-8/a. The ranking of risk values due to non-carcinogen pollutants by drinking water is Pb>fluoride (F)>Hg, within Pb accounting for 44.77%, fluo-ride (F) accounting for 34.30% and Hg accounting for 20.92%. The average individual carcinogenesis annual risk of Cr(VI) is the greatest, achieving 8.91×10-4/a. The ranking of risk value due to chemical carcinogen by rural drinking water of Ya’an is Cr6+>As>Cd, within Cr6+ accounting for 91.12%, As accounting for 5.89% and Cd accounting for 3.00%. Based on this, the strategy and measures of the health risk management are put forward. This study has worked efficiently in practice. Compared with the same kind of methods which have been found, the paper has the outstanding results for the health risk assessment of the rural drinking water safety.展开更多
