旅游建筑水环境后效与调控模型

Effect of Tourism Buildings on Water Environment and Its Controlling Model

许多风景区内或其流域上游 ,都建有旅游建筑 ,而且在急剧增多 ,导致自然环境日趋恶化 ,其中乱建疗养院和旅馆的影响最为严重。通过实地监测并全面分析张家界金鞭溪水环境演变趋势 ,发现住宿设施对水环境的影响 ,比其他游乐设施更为明显。金鞭溪水质恶化主要表现为蓝藻 ,绿藻迅速繁殖 ,感官质量下降。主要原因是磷污染较重 ,总磷年均值 10 0 %超标。基于水环境因子的动态阈值调控模型 ,计算得出 :在不超出金鞭溪水质标准 :总磷≤ 0 .0 2前提下 ,其上游接待区住宿设施生态阈值的动态系列 :春季临界床位数为 1186,夏季为 3 0 5 7,冬季为5 45 ,秋季为 3 3 3。

There are some buildings within most scenery spots. They take the environment go to bad. The main reason is that more and more hotels are built. After field monitoring and analyzing the tendency of the environment in Zhangjiajie National Forest Park, we found that the effect of the hotels is more evident than that of the others. The most glaring change is the declining of the water quality in Jinbian stream. Main expression is blue green algae breeding quickly. The main reason is that phosphate content surpass the set standard in the discharging waste water from Luoguta, the reception area in the upstream. A threshold model for the most fragile environment factor was given in this paper: L={(C N-C 0)Q+KXUC NQ}/P·R-L 0. On condition of no surpassing the set water standard in Jinbian stream, the most fragile environment factor , that is phosphate content≤0.02,we computed the dynamic threshold series for tourist lodgings in the upstream of Jinbian stream:the most quantity of beds in Spring,Summr,Autumn and Winter is 1186,3057,545 and 333. The scale of building in the upstream of Jinbian has built in excess of the threshold
