| 摘 要： | 通过设置了12个监测点第一次对拆除围网后的东太湖水质进行了全面的调查,揭示了氮磷指标的空间分布特征及形成原因。结论表明:东太湖在东西方向上存在浓度西低东高的特点,南北方向上存在浓度降低的变化趋势。造成这种现象的主要原因是水生植物腐烂形成底泥厚薄的不同,水深也不同。在风浪的作用下,通过底泥释放影响了水质;另外试图通过不同年份监测点的水质对比揭示围网拆除对水质的影响。

| Abstract: | By setting 12 Monitoring Sites in East Tai Lake after pulling down the enclosure of crab farming.The paper investigates the water quality of East Tai Lake comprehensively for the first time.The distributions of TP and TN are discussed.The reasons of which are explored further.The conclusions demonstrate:the concentration of TN and TP tend to be higher in the east of the lake but lower in the west.There exists decline trend from north to south.The further study show it is decay of aquatic plants that cause t... |
