城市森林公园水系流场模拟及水环境综合整治——以上海共青森林公园为例

Study on Simulation of Water Flow Field and Comprehensive Improvement of Water Environment in Urban Forest Park——A Case Study of Shanghai Gongqing Forest Park

上海市共青森林公园有相当大的面积为水面,但公园水系的现状不容乐观。除了游客数量的增长带来的污染外,水系的先天不足也是导致水环境恶化的重要原因。利用软件对公园现有水系流场进行模拟分析,发现水系总体流动缓慢甚至不流动。为了改善这一情况,在新开河道的基础上利用黄浦江引调水,模型显示这些措施能够明显地改善水系流动状况,提升水系的连通性。在此基础上实施点面源污染控制、水生态修复等工程措施和其他非工程措施,将较好地改善公园的水质,提升公园总体景观效果。

As the only forest park in Shanghai, Gongqing Forest Park is an indispensable urban green space and a famous tourist attraction. As the development of the park, the status of park water system is not optimistic. As the development of the park, the status of the park water system is not optimistic. In addition to the increase in the number of tourists brought about by the pollution, the inherent lack of water is also an important reason leading to deterioration of the water environment. Using the software（ MIKE21） to simulate the existing water flow field of the park, the total flow of water system was found to be slow or not flowing. In order to improve this situation, in addition to communicating water with newly opened river, the Huangpu river is used to divert water. The model showed that these measures could obviously improve water flow and water connectivity. On this basis, engineering measures such as point source pollution control, water ecological restoration and other non-engineering measures would improve the water quality and overall landscape effect of the park.
