[Abstract]:The rapid biological assessment method of macrobenthos can quickly judge the ecological status of rivers under the influence of human activities. It is of great significance to the study of river health assessment and river protection and management. Based on the monitoring data of macrobenthos in 46 samples of Taizi River, the applicability of the Biological Monitoring working Party BMWP index was discussed. The response of BMWP index to important water environmental parameters was studied by variance analysis. The results showed that BMWP index decreased significantly with the decrease of surface water quality level. Regression analysis was used to study the regression relationship between BMWP index and other biological indexes and habitat status. The results showed that there was a significant linear regression relationship between BMWP index and Shannon diversity index (R2N 0.74), zoobenthos integrity index (R2C0.85) and habitat quality assessment index (R2C0.60) (p0.01), which indicated that BMWP index could effectively indicate and reflect different river segments. And the quality of their habitats. The results of river health evaluation by using BMWP index showed that among the 46 sampling sites in Taibei River, the excellent and good sampling points accounted for 45.7, the normal samples accounted for 21.7, the difference and extreme points were 32.6.BMWP index was sensitive to the ecological condition of the river. Can accurately reflect the health of the river. At the same time, the field monitoring, species identification and index calculation are simple, which is a fast biological evaluation index in river health evaluation.
