我国西北地区,幅员辽阔,具有十分丰富的水,热和土地资源,发展农、林、牧生产潜力很大。但这一地区气候干燥,林木稀少,风沙和水土流失相当严重,对农、牧业生产和工矿,交通及居民点危害很大。应当看到,这一地区除了沙漠和水土流失以外,尚有大面积的荒山荒地,可 Northwest China, with its vast territory and rich water, heat and land resources, has great potential for the development of agriculture, forestry and animal husbandry. However, the climate in this area is dry, sparsely populated, and the sandstorms and soil erosion are quite serious. It is very harmful to agriculture and animal husbandry production as well as mining, transportation and residential areas. It should be noted that in addition to deserts and soil erosion, there are still vast areas of barren hills and wilderness in this area.
