广东各地，暖水年平均雨量大于冷水年平均雨量。但年内各月有一定差异。
The results show that in spite of the increase of rainfall the mean annual runoffs for different future climate scenarios are tend to decrease, which implies more serious water shortage will occur.
结果表明：未来气候情景下，即使海河流域降水量增加，年平均径流量仍将可能减少，预示海河流域的水资源将十分短缺；
The evaluation elements are the nature of loess, the inclination of slope, the height of slope, the mean value of annual rainfall, the parameter of ground motion, the type of the structure of slope.
