摘要
为恢复湖泊水生植被，初步研究了建在武汉东湖的大型围隔、围栏中的植物群落和水质的季节动态以及两者间的关系，结果表明：围隔、围栏中，植物生物量明显增加，漂浮植物易定植，水绵和刚毛藻易发生，植物群落结构难以自然地得到优化；养鱼对水生维管束植物的生长和恢复不利；水中总氮与总磷的变化具一致性，它们与水生植物的生物量间关系密切，围隔中水生植物的良好生长使水的总氮。
In order to restore aquatic vegetation in lakes, the seasonal dynamics of phytocommunities and water quality and the relations between them in the large scale enclosure and corral which were built in East Lake, Wuhan were preliminarily studied. The results showed that in the enclosure and corral, the biomass of aquatic plants increased obviously, the floating plants settled down and reproduced easily, the Spirogyra and Cladophora grew easily, the structure of phytocommunities was difficult to be improved naturally. The fish culture wasn′t beneficial to growth and restoration of aquatic vascular plants. The variation of TN (total nitrogen) was consistent with TP (total phosphorus) in water. There were close relations among TN, TP and biomass of aquatic plants. Because aquatic plants grew well in the enclosure, the TN and TP in water decreased obviously.
