土壤侵蚀按照作用力类别可分为水力侵蚀、风力侵蚀、冻融侵蚀和重力侵蚀，其中水力侵蚀在我国是最为活跃的侵蚀类型，降雨是造成水力侵蚀的主要动力。

Soil erosion can be classified into waterpower erosion , wind power erosion , freeze thawing erosion and gravitation erosion .

全球变暖，降水量低且蒸发强烈，大风频繁、强劲且持续时间长，冻融侵蚀强烈是草地退化的动力条件；

Global warming , low precipitation and strong evaporation , frequent strong winds , erosion of freezing and thawing are the dynamic stimulation .

严重的冻融侵蚀同水力侵蚀和重力侵蚀复合起来，对该区的工农业生产造成极大影响。

Serious freeze-thaw erosion gravity erosion with hydraulic erosion and composite up , to the industrial and agricultural production made a great impact .

冻融侵蚀综合指数的最高值出现在第3坡度等级上，其最低值出现在第6坡度等级上。

The highest of the frozen soil erosion index appears in the slope grade three . The lowest appear in the slope grade six .

土壤侵蚀依据外力可分为水力蚀、重力侵蚀、风力侵蚀、冻融侵蚀和人为侵蚀。

According to the external force , soil erosion can be divided into hydraulic erosion , gravitational erosion , wind erosion , freeze-thaw erosion and man-made erosion .

冻融侵蚀的季节性和侵蚀作用的特殊性，使得国内外对这方面的研究开展很少。

Due to the seasonal freeze thaw erosion and particularity of erosion effect that little research work has been conducted on this aspect both at home and abroad .

最后，结合我国冻融侵蚀研究的实际情况，提出了我国今后一定时期内，在冻融侵蚀研究方面的发展设想。

Finally , the tentative plan on freeze-thaw erosion research in china in the future period is proposed combining with the actual condition of this field in China .

根据新疆水蚀、风蚀、冻融侵蚀具有垂直分布规律的特点，在土壤侵蚀分类时主要考虑降水量、海拔高度和年均温等指标；

In accordance with the characteristics of perpendicular distribution of water erosion , wind erosion and freezing melting erosion , the index such as precipitation , elevation and average temperature are mainly considered when soil erosions are classified .

进行冻融侵蚀评价时，要充分考虑土质和土壤本身的含水量及冻融过程中的水分补给、环境变化等因素。

It should fully consider the factors of quality and composition of the soil , moisture content , and moisture content supply during the process of freezing and melting and environmental changes when it conducts evaluation of freezing and melting erosion .
