从中国实际出发，并结合全球水汽循环及水力作用，指出水土流失也是引起海平面升高的一个重要因素。
From the soil erosion state of China and the globe water circulating and the atmosphere falling action, point out that soil erosion is one of the factors of sea level going up.
蒸发率、降水率和降水再循环率在20年中均有增加，表明气候变暖对我国北方地区的水汽循环的影响已经显现。
Evaporation, precipitation and recycling ratios increase during the 20 years, which may be the effect of the climate warming.
为了克服这一负水汽现象，我们采用了“逐步循环订正法”对初值进行了一些特别处理。
In order to overcome this negative water vapour phenomenon, "the method of stepwise cycle reduction" is used to carry out some special treatments for the initial value.
