The quality of the water-ecology environment in the important fishery function areas of Jialingjiiang and Wujiang rivers

The evaluation of the ecological environment in the important fishery function areas of JialinNiang and Wujiang rivers is of light pollution．The heavy metals and organic compounds of several water samples have exceeded the standards．The single pollution index demonstrates that the main contaminants are petroleum-type and total phosphorus，and the total phosphorus greatly exceeds the standards The pH，total phosphorus，volatile phenol，petroleum-type，Cr⁶⁺，and nonaqueous solvable ammonia of the water have coherency． Finally，some countermeasures to improve the quality of waterecology environment in this area are put forward．
