黄河中游地区,长期以来,存在着干旱与水土流失两大问题。这两大问题与该地区的降水特性密切相关。因此研究黄河中游的降水特性,特别是研究与水土流失极其密切的暴雨特性,制定暴雨分区,对于该地区侵蚀预报,治理规划,因地制宜地安排各项治理措施,有着十分重要的意义。对于黄河流域降水的研究,以叶笃正、杨鉴初、高由禧等人尤为称著。他们在1956年完成的《黄河流域的降水》著作,系选用1953年以前的资料,系列较短。
For a long time, there are two major problems of drought and soil erosion in the middle reaches of the Yellow River. These two issues are closely related to the precipitation characteristics in the area. Therefore, it is of great significance to study the precipitation characteristics in the middle reaches of the Yellow River, especially to study the characteristics of rainstorms that are extremely close to the soil and water loss, and to develop the storm subregion. It is of great significance for the region to forecast the erosion, govern the planning and control various measures according to local conditions. For the study of precipitation in the Yellow River Basin, especially Ye Duzheng, Yang Jianchu, Gauguin et al. The “Precipitation in the Yellow River Basin”, which they completed in 1956, uses a selection of data from 1953 onwards, with a shorter series.
