It shows that runoff is closely correlated with the features of individual precipitation, and it is also affected by vegetation within a short period of time. Raindrop erosion, sheet flow erosion and rill erosion on the slope are the main soil erosion patterns; sediment yield occurs mainly in flood season. Human activity and individual precipitation are two important factors that control the soil erosion at a small watershed. Comprehensive management on the slope in a small watershed is an efficient measure of water and soil conservation.

分析表明，小流域的产流方式容易随次降雨条件的变化而变化，植被因素在较小时间尺度内就会影响产流；产沙主要来源于坡面上的溅蚀、片蚀和细沟侵蚀，时间主要集中在汛期；人类活动以及次降雨条件是控制小流域侵蚀产沙的重要因素；在小流域内进行坡面的综合治理是水土保持的有效措施。

Considering a spherical porous carbon particle immersed in a static ambient atmosphere, the combustion characteristics under three basic conditions: frozen flow, equilibrium flow, partial flow are solved in a half-analytical and half-numerical way.
