The benthos in four bays (Rongcheng Bay, Sanggou Bay, Jinghai Bay and Wuleidao Bay) at 19 sampling locations were investigated by taxonomy and calculating the composition, biomass, abundance and diversity indices in the summer of 2006. A total of 13 environmental variables from 19 sampling locations in four bays were analyzed by factor analysis, and spearman correlations of main environmental variables...
Combining the field investigation and the laboratory analysis, this paper reported the findings of plant diversity responses to groundwater availability in the oasis-desert zones of the lower Tarim River of Northwest China, based on the analysis of the diversity indices including species richness index (R), Shannon-Wiener index (H), Simpson index (D), Pielou evenness index (JSW), Whittaker index (β...
The increasing different stress caused by human activities induced changes in Tianjin Binhai New Area intertidal wetlands recent years. To find out whether the ecosystem health status of the wetlands in this area has been changed correspondingly, data of macrobentho abundance and biomass of 20 stations, both in May and August 2007 were applied, and multiple ecological indicators of different levels...
Single-strand conformation polymorphism (SSCP) method was performed to investigate the microbial community in vermifiltration. Vermifiltration was a newly ecological and high efficient process to treat sewage and sludge synchronously. The experimental results indicated that PCR-SSCP can more truly reflect the existing system of micro-organisms groups. Bacillus, the dominant populations, in the vermifiltration...
