摘要:
利用河南省119个气象台站自建站至2003年间不同年限的逐日降雨量资料，采用不同方法分别计算了河南省各县（市）不同时段的降雨侵蚀力，对不同算法的时空差异进行了比较。结果表明：河南省多年平均降雨侵蚀力总体趋势是由北向南、由西向东递增，最大值出现在南部的鸡公山、新县与商城；各地点的降雨侵蚀力在不同年份变异较大，无明显的周期性等规律；各种算法均可表现出时空变化特征，但具体数据差异较大。认为以逐日降雨量为基础的3种算法比较接近实际情况，其中CREAMS模型因其计算简便性可进行较广泛应用。
Abstract:
Rainfall is main cause for soil erosion and water loss. Rainfall erosivity is main dynamic index. Therefore, estimating the rainfall erosivity and analyzing its spatial and temporal variation are the key to predicting soil erosion and water loss. Using the daily rainfall data of 191 meteorological sites in He’nan Province from the year the site establishment to the year of 2003, and the different rainfall erosivity calculating method, this paper calculated the rainfall erosivity of 119 sites across He’nan Province, analyzed the spatial and temporal variation, and compared the different calculating methods. The results showed that the average rainfall erosivity in He’nan Province is generally increasing from north to south and from west to east; the maximum appears in Jigongshan Mountain, Xinxian County and Shangcheng County in the southern part of He’nan Province. The yearly rainfall erosivity of all sites varies much with no periodical principle. All of the calculation method can explain the spatial and temporal variation, but the actual data is much different. The three methods based on daily precipitation data are much close to reality, and in which the CREAMS model could be further used for its easier calculation.
