摘要
土壤风蚀是我国干旱半干旱地区土地退化的主要原因之一,严重制约着农业的可持续发展.笔者从土壤风蚀发生机理、影响因子的角度探讨了干旱半干旱地区农田风蚀危害及防治对策,提出了实施保护性耕作是实现干旱半干旱地区农业可持续发展的必然选择.
Wind erosion is one of the main causes of land degradation in the arid and semi - arid region of China, it limits the development of agriculture at present. Based on the researches of occurrence mechanism and influencing factors, this paper approaches hazards and control strategies of farming soil wind erosion in the arid and semi - arid region, puts forward to pursue protective farming which is the only choice of realizing arid and semi - arid region agricultural sustainable development.
