【摘要】 通过人工调控对虾养殖池的水色、透明度、溶解氧和 COD,建立了较稳定的对虾养殖生态体系。其特征为 ,生产力水平高 ,物质循环速度快 ,各项水质指标在一定范围内的变化幅度和变化速度较快。提出了人工调控虾池生态环境应以维持稳定的浮游植物种群结构和数量为主要内容 ,同时 ,讨论了浮游植物种群结构及数量与相关因素的关系。更多还原

【Abstract】 By artificially regulating the water color, transparency, dissolved oxygen and COD of shrimp pond, comparatively stable ecological system of shrimp culture was established, featuring high level of productivity, fast rate of matter cycle and relatively rapid change speed with the water quality indexes varying within specified limits It is suggested that maintaining stable phytoplankton population structure and number be the major way to artificially regalate the ecological environment of shrimp pond The relationship between the phytoplankton population structure, number and associated factors was also discussed in this pater更多还原
