摘    要:本研究在太湖流域上游的太湖与湖间的区域内,选择了25个监测点,对6种典型水体中TN、TP含量进行了为期1年的动态监测,分析了不同类型水体中氮、磷动态变化特征。其结果表明,畜禽养殖厂周围水体TN、TP含量在4~8月份相对较低;水产养殖场周围水体和居民区周围水体TN含量在1~6月份高于其他时间段,水产养殖场周围水体TP含较低的月份在5~8月,而居民区周围水体TP含量变化无明显规律;农田周围水体TN、TP含量较高的月份在12月至次年5月期间,最大值出现在3~4月;入湖河流与湖水TN含量变化趋势与农田周围水体基本一致,入湖河流TP含量在6~10月期间明显低于其他时间段,而湖水中TP含量变化则无明显规律。

关 键 词:太湖流域  变化特征

Abstract:25 points were selected to monitor TN and TP in 6 kinds of waterbody on the west of Lake Tai Catchment between Lake Tai and Lake Ge. The experiment lasted for one year. The resuhs showed TN and TP in waterbedy around the livestock and poultry farms were lower from April through August; TN in waterbody around farmland and residence was higher from January through June; TP in waterbody around farmland was lower from May through August; While TP in waterbody around residence showed irregular change;TN and TP in waterbody around farmland were higher from December through the next May, and the maximum value appeared from March through April; The change trends of TN in waterbody of Lake Tai and rivers to it as well as the water bodies around them were accordant basically; TP in waterbody of rivers to Lake Tai were lower from June through October, and TP in waterbody of Lake Tai also showed irregular change.
Keywords:TN  TP
