风蚀沙化现象在河北山区普遍存在,在2000年的沙尘暴中扮演了重要的角色。分析了河北省风蚀沙化的原因,结果认为是干旱和人类不合理的生产活动造成了植被的严重破坏,发展为风蚀沙化。提出了防治沙化的5大措施,即增加人工降雨改造利用沙地、发展灌溉农业提高水资源利用率、治理水土流失、优化种植结构、立体开发、建立健全监测预报系统。

The phenomenon of wind erosion and desertification is widespread in mountain area of Hebei province,and it plays an important role in sand-dust storm in 2000. The reason of wind erosion and desertification in Hebei province is analyzed, one is drought, the another is human absurd produce activity that make the vegetation destroyed and land desertification. In order to control wind erosion, 5 measures are brought out that to increase artificial rainfall, to develop irrigated farming and to rise using rate of water resource, to control soil erosion, to optimize the frame of crops and solid expoiting, and to establish control and forecast system.
