这个地区的年降雨量不到300毫米。就像你们所看到的，非常有限的地表水被收集在这条泥泞的小溪里。
With less than 300 mm rainfall a year, the very limited surface water as you see here was collected in this muddy creek.
以地表径流形式输出该系统的水量占年均降雨量的9.4 %。
The surface runoff output is 9.4% of the average annual rainfall.
结果表明：坡耕地、杉木林地的次降雨地表径流量、地表径流侵蚀模数与坡度、降雨量、降雨强度、植被盖度等相关显著。
The results showed that the correlation between total surface runoff and erosion modulus with land use types and those influence factors above was significant.
春季风大风多，降雨量少，气候侵蚀力高，地表植被覆盖率低，土壤表层由于冻融作用变的松散，是一年最易风蚀的季节。
The wind erosion hazard is often intensified by the poor vegetation cover and loosen surface soil due to the freezing and thawing over winter.
