FUNCTIONS AND MANAGEMENT OF MACROPHYTES IN YUQIAO RESERVOIR

本文论述了于桥水库大型水生植物的现状、作用、管理和保护对策及管理和利用中存在的问题.建议:不要盲目地在库中投放大量草鱼; 6月份以前应对大型水生植物实施保护性措施; 8月初开始应尽量多地收割和捞出大型水生植物.同时应加强6～7月份库中大型水生植物管理方案的研究和大型水生植物二次利用的研究.

The current situation, function, management and protective measures of the macrophytes in Yuqiao Reservoir are discussed. The questions existing in the management and reuse of the macrophytes are put forward. The suggestions are as the follows:A large number of the grass carp ( Ctenopharyngodon idellus ( C.d.v ) ) should not be bred in the reservoir blindly.The macrophytes should be preserved and should not be harvested before June, and should be harvested as much as possible from August. On the other hand the managerial and protective scheme for the macrophytes should be researched in June and July and the reuse of the macrophytes should be studied further.
