Abstract:
Objective To know the eutrophic state of Fenhe 1 reservoir. Methods The eutrophic level of Fenhe reservoir 1 was evaluated through measuring transparence,the total concentration of nitrogen(TN),phosphorus(TP),chlorophyll-a level(Chla) and the total count of the algal cells and calculating water TLI(∑). Results Water transparence in low water period was higher than that in common water period,TN concentration in low water period was higher than that in common water period,and it obviously exceeded the related standard limit in Surface Water Environment Quality Standard (GB3838—2002); TP concertration in common water period and low water period did not exceed the limit; Chla level was low;TLI(∑) in common water period and low water period was lower than 50. The total count of the algal cells was 1.67?106/L in low water period,which was much more than that(9.5?104/L) in the common water period. Conclusion Fenhe reservoir 1 is in mesotropher state.
