Abstract:
Based on a review of the lake restoration assessment, lake ecosystem health assessment and other ecosystem restoration assessment at home and abroad, the definitions of lake ecological restoration were summarized. The choice of restoration indicators was introduced from four aspects, i.e. physical and chemical indicators, aquatic biological indicators, littoral zone structure and function indicators, and water amount indicator. Also the method of selecting reference conditions in ecological restoration evaluation was outlined, focusing on two types of assessment methods including biological monitoring method and multi-index complex assessment method, with the introduction of the advantages and disadvantages of both methods. According to available studies, the problems in lake restoration assessment were discussed, and it was pointed out that the large-scale assessment, the long-term monitoring and the establishment of a comprehensive assessment system model should be the focus for further development.
