| 摘 要： | 本文采用灰色系统关联度分析方法,以空间理论数学为基础,依规范性、偶对称性、整体性和接近性原则,计算并分析了益阳大通湖14个生态因子的关联度,关联序结果为:亚硝酸氮氮磷比氨氮总氮硝酸氮浮游动物叶绿素a透明度总磷水深水温浮游植物酸碱度溶解氧。益阳大通湖表现为总氮(包括亚硝酸氮、氨氮和硝酸氮)和氮磷比是优势影响因子。通过灰关联分析发现,大通湖水体水质良好,水体的总氮、氮磷比及总磷都适于浮游生物的生长繁殖,对增加渔产潜力有重要作用。

| Abstract: | Based on space mathematical theory, the principles of normalization, symplectic symmetry, integrality, and accessibility etc., we applied gray system correlation method, with which the correlation degree of 14 ecological factors were calculated for Datong Lake in Yiyang, Hunan. The descending order of correlation was nitrous nitrogen > phosphorus-nitrogen ratio > ammonia nitrogen > total nitrogen > nitrate nitrogen > zooplankton > Chl a > transparency > total phosphorus > water depth > water temperature > phytoplankton > pH value > dissolved oxygen. It shows that total nitrogen (including nitrous nitrogen, ammonia nitrogen and nitrate nitrogen) and phosphorus/nitrogen ratio were the advantage factors. The gray correlation analysis showed that the lake water quality was good, and total nitrogen, phosphorus/nitrogen ratio, and total phosphorus were suitable for plankton growth and proliferation, which is very important to fishery production potential improvement. |
