Unlike most saline lakes, the Chinese ones were formed in depressions entirely by runoff from the surrounding topography, hence greatly affected by seasons and variation in salinity, with microbial composition and functions being the most influenced. Determining the nature of key environmental drivers such as microbial dynamics is necessary. Therefore, the current study applied metagenomics study approach to determining the microbial community diversity and functions across sediment regimen (clay [NT], sandstone [FS] and salt-bearing [SY]) of the East Taijinar Salt Lake, China. The result indicated that members of Actinobacterium did not exhibit variability across the sediment types while members of Firmicutes and Proteobacteria showed some variabilities, and had highest dominance in clay (NT) and sandstone (FS) sediment type as compared to the salt-bearing (SY) sediment type. Based on UniFrac, STAMP analyses there was significant differences (P < 0.05), with the weighted-UniFrac approach indicating the highest abundance under the clay sediment type. According to NMDS analysis, there was closer similarity in microbial composition between the clays sediment type (NT) and sandstone (FS). Furthermore, through the cladogram, it was visualized that there was very low representation of bacterial species from the salt-bearing (SY) sediment type as compared to other sediment types. More COG and KEGG pathways were dominant under the clays (NT) sandstone (FS) sediment types as opposed to the salt-based (SY) sediment type. Based on this result, in-depth studies on spatial and temporal variability in microbial community diversity and eco-genomics functions across the sediments of the East Taijinar Salt Lake is recommended.

The main circuit structure of single-phase wind power system, grid inverter model with modeling, and the design of the filters are introduced. Comparing two control strateies between several common control strategies with using Matlab/simulation tools. The results show that quasi-PR control has better performance.

This paper discusses the placement of the wind power plant’ selection process,wind-farm built in Donghai county,Jiangsu province is proposed to select the appropriate wind-farm from the aspects such as macro-sitting and micro-sitting selection.On the basis of the actual measurement data in the site,using histogram and meteorological rose evaluate wind energy resources of the wind-farm,to determine the selection of the wind-farm site and wind turbines and the layout of wind turbine generator system.Special software is adopted to improve the professional evaluation and the effectiveness of the site selection.
