摘要
选取溶解氧、悬浮物、生化耗氧量、氨氮、总磷和氟化物6个评价因子,采用加权综合模型对沙湖不同功能区水质状况,以及1991年以来水质变化趋势与旅游人数变化的耦合性分析,反映出沙湖水体环境质量变化主要受旅游开发影响所致。
The research Apply weight composite model to evaluate the characters ot time-space of water quality of Sand Lake. DO, SS, BOD5, NH3-N, TP and Eluoride are selected as dominating contamination facts. The results show that： the weighted composite index of tourism regions are higher than others, and the water quality has showed descending tend in the past 12 years. The results are related to the open of Sand Lake as the national scenic areas.
