东昌湖水环境研究现状及展望

RESEARCH PROGRESS AND PROSPECT FOR WATER ENVIRONMENT OF DONGCHANG LAKE

东昌湖是长江以北最大的城市人工湖泊,具有蓄水、防洪、生态、景观、平衡地下水源等多种功能,对聊城市生态环境、经济社会的发展起着举足轻重的作用。在以往的文献中,学者们主要从水生生物、浮游生物生态学及生态功能区划的角度对其进行了水质评价及研究,并为东昌湖的综合开发和可持续利用提出了对策与建议。在综述以往研究成果的基础上,针对东昌湖的研究现状及存在的主要问题,提出了东昌湖研究的重点和方向。

In north of the Changjiang River, there is the biggest man-made lake-Dongchang Lake, which has a variety of functions for conserving water, defending flood, improving ecological environ- ment and landscape, balancing groundwater. Furthermore, it plays an important role in promoting e- conomy and social development of Liaocheng. In the past literatures, scholars carried out intensive studies and water quality assessment mainly from the viewpoint of aquatic organisms, plankton ecology and ecosystem services and then proposed feasible countermeasures for the comprehensive development and sustainable use of Dongchang Lake. Based on the results of research progress and the problems of Dongchang Lake utilization, the focuses and directions for futural research on Dongchang Lake were put forward in the end.
