With the theoretical basis of aerodynamics, using fluid dynamics software (Fluent), simulated examination has been performed to analyze near-surface air currents, wind speed profile and windbreak performance of sand-bag barrier with different sizes. The results show that, below the surface of 0.5m height, the changes of wind profile of monitored section are consistent, with little difference, but the wind speed decreases between 0.5~2.0m height. There are clearly three partitions of the near-surface air: accelerated upwards area, low-speed sink area and low-speed recirculation zone. They are located in front of the sand barrier protection projects, above the top of the protection zone and inside the barrier, respectively. In low-speed recirculation zone, there exist two horizontal axis eddy current and the velocity at eddy center is minimum. In addition, it can be seen that 0.5m height is a critical point to distinguish factors of affecting wind speed. In the range of 0~0.5m, the height of sand barrier is the main factor of wind speed, while in the range of 0.5~2.0m, the size of sand barrier is the main factor. Considering comprehensively the above factors, it is realized that the sand-bag barrier with 2m×2m size has the most remarkable protective effect.

The rainfall is the main soil water supply to the soil of desert-steppe. It divides into three parts, evaporation, infiltration and runoff, after falling on to the surface. Those three parts are affected by many factors. Studies of rainfall division in desert-steppe were rare, the proportions of evaporation, infiltration and runoff are uncertain. So Under the condition of different vegetation, we conduct six times rainfall simulation experiment under different rainfall intensity. Simulation shows that rainfall process, the surface coverage and soil condition affect division. The evaporation section of rainfall accounted for 1/2 ~ 2/3. Infiltration section accounted for 30% ~ 50%. Runoff is the smallest. The rainfall intensity plays a decisive role on the runoff. Different vegetation coverage, division proportion is different. The interception and delay function of vegetation main effect evaporation and runoff, it can make the evaporation increased to more than 70%, reduce runoff to a third. Water content of soil profile before rainfall is the main factors affecting infiltration volume. The soil moisture before rain affects the infiltration rate at the beginning of rainfall. If rainfall duration is long enough, infiltration capacity is almost a constant. © (2014) Trans Tech Publications, Switzerland.

The rapid development of wind farms construction, wind resource assessment is correct or not directly affect the future effectiveness of wind farms is good or bad. Wind resources in the slope of the windward slope, the wind speed climbing effect makes the wind velocity increases.On the windward slope, the wind resource at each location varied widely. Therefore, the windward slope actual wind speed at any position have to use the measured data at the bottom and top of mountains according to wind speed changes of slope to Calculate. This article discusses how to obtain more actual wind speed at distances on different slope and the slope of at each location. © 2011 IEEE.

The life quality of livestock population in different time and space is determined by the limitations of water and grass resources and by the fixed position of resource. Carrying capacity is a variable which is closely related to the resource that the prairie can supply. Based on the systematic analysis on the grassland resources, water resources in Damaoqi desert steppe and on the ecological principles of "determining livestock by grass and keeping a balance among the water, grass and livestock", the threshold expansion of the carrying capacity was analyzed in the desert grassland within the environmental capacity of water and grass resources. Studies suggest that if the ecological patterns are safe in the grass and water resources, the threshold of carrying capacity would be expanded and the animal husbandry would be sustainably and scientifically developed through the construction of efficiently irrigated grassland, the adjustment of livestock varieties or herd structure and scientific grazing and so on. © 2011 IEEE.
