A kind of polymer degrading microbe JHW-31 was selected from Daqing Oilfield. The microbe was inoculated and cultured in the culture medium confected with polymer and a little sucrose for 7 days under the condition of pH 7.2 and temperature 45℃. The viscosity reduction rate of the polymer reached 92.1%,and the molecular weight of the polymer decreased from 18×106 to 0.5×106. The gross of the polymer decreased a little bit.

结果表明：干燥温度越高，干燥各阶段水分扩散系数及平均水分扩散系数也越大；初始高含水率阶段，随含水率逐渐降低，水分扩散系数呈逐步增加趋势，在纤维饱和点附近时达最大值；随后，随含水率逐渐降低呈逐步减少趋势。

The results showed:(1)Nitrogen addition changed the soil physical and chemical properties, enhancing the content of NO3—- N available resources in the soil, increasing the plants height and cover, reducing the vegetation light penetration. With increasing of N addition, both the species richness and the diversity decrease sharply (P 0.001).(2)N addition increased the aboveground biomass significantly (P 0.05). With increasing of N addition, the aboveground biomass increased first then decreased, and the grasses biomass increased while the forbs and legumes biomass decreased.(3)There was a significant linear positive relationship between species richness and vegetation light penetration (P 0.05), and also between aboveground biomass and soil NO3—- N content (P 0.05). The relationship between aboveground biomass and species richness was negative upon enhanced N supply.
