黑龙江省低山丘陵区土壤贫瘠,农业生产活动剧烈,加之降雨多以夏季暴雨为主,造成了严重的土壤侵蚀现象。通过对宾县三岔河小流域7个试验小区径流和产沙观测资料的分析,总结得出不同水保措施下的水土保持效益,为合理安排耕作方式提供参考。图1,表2,参16。
The soil in low mountain and mound area of Heilongjiang province is barren, and the people's agricultural activity is intense. Additionally, rainfall of this region is mostly in heavy rain and raln-storm type. All these result in serious soil erosion. With the runoff and silt observation data analysis of seven experiment plots in Sanchahe small watershed, Binxian county, water and soil conservation benefits of different measures were summarized, and a suggestion for the cultivation method of this region was put forward.
