摘要
我国北方旱作农业区土壤风蚀问题十分严重,不仅对当地形成生态灾难,而且风蚀的细粒物质可随风输移到很远的地方,对广大地区的环境造成影响,尤其在沙尘暴期间,这种影响更为突出;加强北方早作农田土壤风蚀防治工作十分重要,应根据土壤风蚀发生的过程,针对影响风蚀的因素,采取有效的防治技术措施,加强土壤风蚀的防治;在查阅文献的基础上,对土壤风蚀的过程、影响闲素、防治的主要技术措施进行了较全面的分析和阐述。
Soil wind erosion is very serious on arid and subarid agricultural lands in the north of China. It not only causes ecological disaster in the erided area but also deteriorates atmospheric quality in large region with free particles transported buy wind. The effects are very harmful during sand storm. Therefore, it is important to enhance the measures to eontrgl wind soil erosion in arid and subarid agricultural lands.We should base on he occurrence process and affection factors of soil erosion to take effective steps to control it. This paper founds on a lot of research documents to thoroughly analyse the occurrence process and affection factors of wind erosion and expatiates the main controlling technology measures.
