景观河流(津河)水质变化的研究与控制

随着城市的发展,城市景观河流的治理和维护成为许多城市必须面临的问题.为此,以津河为研究对象, 在对其水质监测的基础上,利用QUAL2E模型建立了津河水质模型,模拟和预测津河的水质.在建立津河水质模型中,模型参数的估值一部分选用经验数据或根据经验公式计算,一部分通过模型反求的方法获得,经验证,这种方法在尝试的3种方法中效果最佳,同时也验证了该方法的可行性.最后,结合天津市有关景观水体环境保护规划和津河的实际状况,提出了津河水污染的控制措施.

Study and Control of Water Quality Changes in Scenic Rivers (the Jinhe River)

With the development of cities, the problem of management and maintenance of scenic rivers is faced by many cities. The Jinhe River was monitored, and water quality model was built by using the QUAL2E to simulate and predict water quality of the river. In the water quality model, some parameters were from experience data, or given by formulae calculation, and others were reasoned out through the model. The method of reasoning out parameters through the model was proved to be feasible and the best of the three. Finally, combined with environmental protection regulations about scenic rivers in Tianjin and the real conditions of the Jinhe River, measures to control water pollution were put forward.
