  • 摘要: 为构建稳定的大莲湖生态系统，对大莲湖生态修复区内采取了地型塑造、水系沟通、植被恢复和人工增殖放流等措施，分析了生态修复区浮游植物，营养盐的变化状况和放流鱼类生长情况。结果显示，生态修复实施后，水体中藻细胞密度较人工养殖池塘明显下降，藻类结构发生明显变化，蓝藻所占比重逐渐减小，水体中的氮，磷和叶绿素明显下降；放流鱼种生长和成活情况较好。因此，采用生物操纵技术措施可实现湖泊的生态恢复。
    Abstract: Several measures including shaping the physiognomy， dredging the water system， vegetation restoration and artificial reproduction of fish were carried out to construct a stable ecosystem of Dalian Lake. Changes of phytoplankton population， nutrient salt concentration and fish growth were analyzed. The results showed that algae density of Dalian Lake was significantly lower than that in artificial pond. The plankton population changed greatly with the reduced proportion of cyanobacteria observed. The concentrations of nitrogen， phosphorus and chlorophyll decreased significantly compared to the former conditions. In addition， survival and growth of fish released were quite satisfied. The success of this ecosystem restoration project was certified by the above observations. Thus， biomanipulation could be effective in lake ecosystem restoration.
