克拜地区位于黑龙江省中部,是大小兴安岭延伸的山前台地。海拔200～300米,地表波伏起伏,漫川漫岗,是我省重要的商品粮基地。但由于春季干旱多风,夏季降水集中造成强烈水土流失。特别是随着耕作机械的增多,推广了以平翻为主的耕作法,既破坏了团粒结构,又损失了大量水分。加重了土壤的风蚀和干旱。同时,在耕层底部又形成了坚硬的平板状犁底层,雨水难以下渗,易形成地表径流,引起土壤流失。据调查,本区年土壤侵蚀模数达7000吨/平方公里。
Kibai region is located in the central Heilongjiang Province, is the size of the Hinggan Mountains extension of the foreshore. 200 to 300 meters above sea level, undulating surface waves, Mangchuan Man Kong, is our province an important commodity grain base. However, due to the spring drought and windy weather, the summer rainfall has caused intensive soil and water loss. Especially with the increase of tillage machinery, the tillage method based on flat turning was promoted, which not only destroyed the aggregate structure but also lost a large amount of water. Increased soil erosion and drought. At the same time, at the bottom of the tillage layer, a hard plate-like plow bottom was formed. Rainwater was difficult to infiltrate, resulting in surface runoff and soil erosion. According to the survey, the annual soil erosion modulus reaches 7,000 tons / square kilometer.
