Hydrology plays a dominant role in wetland plant distribution and microbial composition, but few studies explicitly attempted to relate the linkage between wetland vegetation and microbial community. The present study consisted of five wetland plant communities along three adjacent flood gradients zones(zone 1 dominated by Carex appendiculat, zone 2 dominated by Eleocharis ovate, and zone 3 dominated by Phragmites australis/Bidens pilosa/Calamagrostis angustifolia, which formed separate, monoculture patches). Gram negative and arbuscular mycorrhizal fungal phospholipid fatty acid(PLFA) are more abundant in the site with short flooding period(zone 3) than in the site with long flooding period(zone 1), and they are also different in the P. australis, B. spilosa and C. angustifolia of zone 3. Principle Component Analysis(PCA) showed that the flooding period could explain 92.4% of variance in microbial composition. Redundancy Analysis(RDA) showed that available nitrogen(AN), total nitrogen(TN) and soil organic matter(SOM) could explain the 79.5% of variance in microbial composition among E. ovata, P. australis, B. pilosa and C. angustifolia. Results demonstrated that flooding period was the main factor in driving the microbial composition and plant-derived resources could influence soil microbial composition in the seasonally flooded zones.

The global annual averaged Surface Air Temperature Anomaly （SATA） in 2015 and its rank in the historical instrumental records are analyzed using the CRU, NASA, and NOAA datasets. All datasets indicate that 2015 is the warmest year, which is 0.74℃ warmer than normal years from 1961 to 1990 in the HadCRUT4 data-set. The most evident warm anomaly occurs over land, especially at high latitudes. The averaged SATA over land is 1.13 ℃, which is 0.54℃warmer than that over oceans （0.59℃）. Because an El Niffo event occurred in 2015 and 1998 and 1998 is also the warmest year in the twentieth century, these two years are compared to explain the formation of the warmest climate. A statistical approach that is known as the Ensemble Empirical Mode Decomposition （EEMD） is employed to isolate the components with different timescales, which range from interannual to centennial and a long-term trend. In 2015 the developing El Niffo may have contributed an anomaly of 0. 1 0℃, while this value is 0.1 8 ℃ for 1998. The contribution of the decadal-multidecadal variability and beyond to 2015 is 0.64℃, which is significantly larger than that of the interannual anomaly components （0.10 ℃）. This indicates that the warmest climate in 2015 occurred in the context of the tirnescales beyond the interannual.

An independent method is proposed to estimate the dispersion velocity of galactic dark matter *** method is based on the observed quasar-galaxy association samples that are caused by gravitational *** resulting dispersion velocities are much higher than-220km·s^(-1),a value expected from the virial theorem,which shows that the conventional assumption of virialization may be invalid in the halo regions of galaxies.
