在充分考虑风雪具体物理特性的基础上,通过对经典Boltzmann 方程进行离散来构造三维风场,并根据风雪的交互作用规律,建立起雪的飘动、沉积、侵蚀等变化规则,进一步采用一系列简化和加速绘制的方法,具有真实感地实时绘制出不同风速下不同降雪量的风雪场景。

It was found that, for the control treatment the average runoff depth was 3.72mm per 10mm, the water loss index was 37.2%, the average soil erosion was 43.6 kg*hm-2*10mm-1, and the soil erosion modulus was 7.42 t*km-2*a-1, which are all high in the 4 treatments. For the other three treatments, the surface runoff and the average soil erosion amount were 2.20%-67.08%and 43.81%-90.83%lower than those of the control, respectively. The most effective pattern for soil conservation was the artificial forest with underbrush treatment, and the best water conservation pattern was the treatment of planting tea bush on contour terrace.
