| 摘 要： | 调查分析了长江上游宜宾境内地表水中N、P状况和各种经济活动对水体TN、TP的贡献。金沙江、岷江N和P指标大多数满足Ⅰ类至Ⅲ类标准限值要求，但进入宜宾城区后水质明显下降。宜宾市各种经济活动中，禽畜饲养活动和居民日常生活是人为氮、磷输入的主要因素。其中，禽畜饲养活动对人为氮、磷输入的贡献逐年增加，在1999～2005年分别从43.54%、66.05% 增至81.37%、57.81%；1999～2005年，宜宾市区的主要经济活动对溶解态无机氮、磷的贡献分别增加了3成和1倍。禽畜饲养活动对水体中氮、磷的贡献超过了非点源农田径流的贡献，同时也是造成研究区水库湖泊富营养化的主要因素。

| Abstract: | N and P state in surface water in Yibin area in the upper reaches of Yangtze River and the contribution of various economic activities to N and P in water were investigated and analyzed.The indexes of N and P in the Jinsha River and the Minjiang River generally meet the limit values of grade I to grade III water quality,but the water quality in Yibin City and downstream obviously worsen.For various economic activities,poultry raising and residential daily life are the main influence factors of N and P conte... |
