我校是江苏省首届绿色学校、南通市首批十佳校园,校园内的文津河原已经存在几千年,“S”形的文津河赋予美丽校园的灵动。近年来,我们发现,每到春末夏初,文津河水逐渐变绿,池中鱼儿“泛塘”现象的发生频率逐年增高,走近池塘,还会闻到一股腥臭气味。我校学生多数来自于农村,对于因水土流失、生活废水过度排放等因素引起的富营养化现象比较常见,但多数学生对这类水污染事件发生的原因及如何防治缺乏深刻了解。因此,分析水绿鱼死的原因、设法改善污染水质、提出预防水污染措施等,成为我们设计“池塘生态问题的调查及治理研究”课题的主要目的。我们期望,通过开展池塘生态 My school is the first green school in Jiangsu Province, Nantong City, the first batch of the top ten schools, Wenjinhe River campus has existed for thousands of years, “S ” -shaped Wenjin River gives the smart campus smart. In recent years, we found that every spring and early summer, the Wenjin River water gradually turns green, and the frequency of the fish “Pan Tong” in the pond increases year by year. As the pond approaches, it smells a stench. Most of our students come from rural areas, but eutrophication caused by water and soil loss and excessive discharge of domestic wastewater is more common. However, most students lack a deep understanding of the causes of such water pollution incidents and how to prevent and cure them. Therefore, it is the main purpose of our project to investigate and investigate the ecological problems of ponds to analyze the reasons for the death of aquatic green fish, try to improve the quality of polluted water and put forward measures to prevent water pollution. We hope that through the pond ecology
