| 摘 要： | 四湖流域水环境恶化已影响到当地生产和群众生活,亟待对四湖流域的水环境污染现状进行调查与评估。于2010年春季在四湖流域的主要湖泊以及四湖总干渠进行了水质现场监测和水样采集,共采集了84个样点,每个样点测定了12项水质指标,并对测定结果中四湖流域总氮、总磷、高锰酸钾指数等水质指标的空间分布进行了分析。分析结果表明:四湖流域的两个主要湖泊,长湖和洪湖均受到不同程度的污染,长湖为重度污染,洪湖为轻度污染,从长湖流入总干渠中的水质多为中性或略偏碱性,总磷、总氮含量超标几倍到几十倍,在靠近长湖的总干渠上游段为重度污染,靠近洪湖的总干渠下游段为轻度污染。各水质指标浓度总体趋势上,长湖的要大于总干渠,总干渠的大于西干渠,西干渠的大于洪湖。

| Abstract: | It is necessary to investigate and evaluate the water pollution in Sihu Basin as the water deterioration has influenced the local production and people’s living.Our research group monitored and collected 84 samples in the lakes and channels of Sihu Basin for testing 12 water quality parameters and analyzing the spatial distribution of TN,TP,CODMn.The results indicated that the Chang Lake and Hong Lake were both polluted in different degree;the water quality of Chang Lake was more seriously polluted than Hong Lake.The pH value of Chang Lake was mostly neutral and weakly alkaline,and the total phosphor and nitrogen ware out of limits seriously.The upstream reaches of main channel were more seriously polluted than downstream reaches.In general,the water quality in Chang Lake was worse than main channel,the main channel was worse than west channel,and the west channel is worse than Hong Lake. |
