%X The water environment variables of Zhangze Reservoir were surveyed monthly in 2007 to illustrate horizontal and vertical patterns of water environment. The results showed that interannual difference of water environment variable is significant, and the discharge of external pollutants was the first important factor. In the nearly decade, the concentration of water environmental parameters in Zhangze Reservoir assume a non-significant increasing trend year by year, and their monthly variations is also dramatic. The concentrations of oxygen BOD5, CODMn and DO were the highest in February and March. In July, that of DO and NH3-N were the lowest. In terms of seasonal changes, the order of concentration of TP was: average>rainy season>dry season. Seasonal factors, such as temperature, rainfall, Zhangze Reservoir's water storage capacity, play a notable affection on water environment factors. Temperature stratification strengthens vertical separability of water environmental factors.
