"March to the Desert" PPT courseware 3

writing background:

From June to July 1959, Zhu Kezhen visited the three provinces and districts of Inner Mongolia, Ningxia and Gansu along the Baolan Railway. The hazards of sandstorms in Ningxia are one of the focuses of its investigation. Along the way, desert covers the roads and threatens farmland, canals, roads and towns. Large sand dunes and sand pour into the water along the Yellow River, increasing the amount of sediment transported by the Yellow River. Zhu Kezhen pointed out that the human factors causing sand are unreasonable deforestation, destruction of grassland, excessive reclamation and grazing. To control desertification, we must first build confidence and protect existing grassland and forest belts. He said: "Although there is little rainfall in arid areas, it is entirely possible to plant forests and plant grass. In some places, there is abundant groundwater that can be used." This article was later published in the People's Daily.
