| Abstract: | The comprehensive analysis was made to the pollution of ammonia-nitrogen in Xiangjiang River basin of pollution condition and change trend in the latest 10 years. The results show that the pollution of ammonia- nitrogen in Xiangjiang River basin despite ups and downs rise trend ,but still has significant changes 07 development to peak,then gradually decreased; Ammonia-nitrogen pollution in Xiangtan Section of Lianshui River were not significant decline since 2006; Ammonia-nitrogen pollution in Xiangtan section of Xiangjiang River basin average not to exceed bid since 2008. |
