旅游开发利用对水体质量影响的综合评价——以张家界国家森林公园为例

Integrated Evaluation of Recreation Development Effects on Water Quality--Take Zhangjiajie National Forestry Park as a Study Case

对已有的水体质量评价模型及聚类权的优缺点进行了分析和比较,确定了最优水质评价模型.对聚类权的计算模型作了改进,提出了新的聚类权计算模型.在此基础上,对张家界国家森林公园境内水体质量进行了评价.结果表明,旅游开发利用已对公园内金鞭溪中、上游的水质造成了较为严重的污染,必须采取有效措施减少公园废水的排放源及排放量,同时加强公园污水的净化治理,以实现公园的可持续发展.

Based on analyzing and comparing the merits and shortcomings of some former water quality evaluation models and the clustering weights, the best water quality evaluation model is selected and the old model of clustering weights is improved and a new one was presented. Then with the application of the models, the water quality in Zhangjiajie National Forestry Park is evaluated, and the results shows that recreation development affected the water quality of the middle and front parts of the Golden Whip Stream in the park seriously. It is must to take efficient measures to reduce the number of discharging sources and the amount of wastewater, meanwhile the work to purify the wastewater should be fastened thus to realize the sustainable development of the park.
