By monitoring and analyzing we consider that the higher bacteriological indexes of water quality of Hongyan river are original quality of coteau and woodland;that the total phosphorus(TP),total nitrogen(TN),permanganate salt index and total hardness on the high side are connected with rich organic matter in ground and hydrologygeology condition.

In different pollution area of Honghe River mainstream,we set up 5 environmental monitoring sections,and meanwhile select Jiahe section of Lixianjiang River as comparison,which has good natural condition,less population,and no industry.

Based on the observational data of the Honghe River flow in Manhao hydrometric station and precipitation field,temperature field in Yunnan,using the wavelet transform and correlation analysis method,the characteristics of the transboundary flow change of the Honghe River and the relationship with precipitation field and temperature field over Yunnan are analyzed.
