旅游活动对四川升钟水库水质的干扰度研究

运用TADI指数研究升钟水库的旅游活动对水体环境的影响，比较了旅游活动中各个环节对水体的影响程度，指数越大，对水质影响越大。结果表明：升钟水库景区旅游人均TN、TP污染物排放量分别为3.57g／d、0.59g／d，升钟水库景区7类旅游接待设施综合干扰指数排序为：住宿类渔家乐T1〉渔家乐餐厅T2〉酒店T3〉餐馆T4〉摊贩T4〉公厕T7〉博物馆T6，住宿类型渔家乐（T1）对水质干扰最大，属高度干扰型；博物馆（T6）对水质干扰最小，属低度干扰型。不同的食宿组合方式中，渔家乐住宿餐饮型的TADI指数最大，对水质的干扰最强，仅在餐馆就餐则TADI指数为最小，对水质干扰也最弱。

Study on the Interference of Tourism Activities on Water Qulity of Shengzhong Reservoir

Based on the index of TADI, effects of tourism activities on water environment of Shengzhong reservoir were analyzed, and the influence degrees of each link were compared. The results showed average TN, TP emissions were 3.57g/d and 0.59g/d per person respectively in Shengzhong reservoir scenic area. Tourism comprehensive interference indexes of seven types of tourism reception facilities in Shengzhong Reservoir scenic area was in the order of T1 （ accommodating in fishing lodges） 〉 T5（ eating in fishing lodges） 〉 T2（hotel） 〉 T3 （restaurant）〉 T4 （vendor）〉 T7 （ public toilet） 〉 T6（ museum）, in which the larger the index, the greater influence on the water quality. Accommodating in fishing lodges（T1 ） had the largest affect on the water quality, which belonged to high interference type, While museum （T6） exerted the minimum influence on the water quality, which belonged to low interference type. Among different combination of eating and accommodating, Accommodating and eating in fishing lodges showed the maximum disturbance to the water quality with the largest index of TADI, while eating in the restaurant showed the weakest interference with the smallest index of TADI.
