宜兴、溧阳河流主要水质指标的年际变化与成因分析

Abstract

Abstract: Yixing and Liyang′s rivers are taken for case study to explore the evolutional trend of the water environment of the watershed and main factors affecting the evolution of the water environment.The results show that the annual variation of TN and TP does not show any ascending trend,but that of COD_Mn does otherwise.Industrial point-source pollution is the main factor affecting COD_Mn concentration in the water,whereas high rates of fertilizer application is the major non-point source pollution affecting TN index,and domestic pollution is the major factor affecting TP index in the water.

Key words: evolutional trend, water environment, affecting factors, variation trend
