通过对滦平中心试区黄绵土、粗骨土坡耕地两种主要耕地类型及粗骨土荒坡水土流失的观测研究,表明:粗骨土坡耕地年径流量和侵蚀量分别为黄绵土坡耕地的8%和1%,相差悬殊。指出;该区治理水土流失的重点为黄绵土坡耕地。
Through the observation and study of two main types of arable land on the loessial and coarse-grained slopes in Luanping Experimental Zone, the results show that the annual runoff and erosion amount of the cultivated loessial slope soil are as follows: 8% and 1%, a great difference. It is pointed out that the key point of soil and water erosion control in this area is sloping farmland of loessial soil.
