辽西北地区风蚀造成农田沙化、作物产量下降,严重影响人们的正常生产和生活,而人类不合理的经济活动是农田风蚀的主要成因。因此,地方政府一方面应采取退耕还林还草、完善防护林体系、推广保护性耕作等措施增加地表覆盖率,另一方面应发展地方经济以减轻环境压力,以控制和防治农田风蚀。 Wind erosion in northwestern Liaoning caused desertification of farmland and decreased crop production, which seriously affected people’s normal production and life. The unreasonable economic activities of human beings are the main causes of farmland wind erosion. Therefore, on the one hand, local governments should take such measures as returning farmland to forests and grasslands, perfecting the system of shelterbelt, promoting conservation tillage and other measures to increase the surface coverage. On the other hand, local governments should develop local economy to reduce environmental pressure so as to control and prevent farmland wind erosion.
