营造防护林是征服风砂、改造自然、保证农田丰收的有效办法,因此防护林的建设是非常必要的。这里首先谈谈我国营造防护林的初步成就。我国北部地区因接近蒙古沙漠和内陆沙荒,森林稀少,气候多风而干旱,有时流沙侵害农田村庄(图1)和道路,给当地生产发展与人民生活带来极大的障碍。解放以后,党和政府学习苏联营造防护林的先进经验,先后在冀西、豫东、东北西部、内蒙东部和陕北等地营造防护林,以防止自然灾害。其中规模较大的为东北与内蒙间
The construction of shelterbelts is an effective way to conquer wind and sand, transform nature, and ensure the harvest of farmland. Therefore, the construction of shelterbelts is very necessary. Here first talk about the initial achievements of China to build shelter forest. Due to the close proximity to Mongolian deserts and inland desertification, the northern regions of China are sparsely populated with drought-prone climate, and sometimes sands invade farmland and villages (Fig. 1) and roads, which poses great obstacles to local production and development and people’s lives. After the liberation, the party and the government learned from the advanced experience of the Soviet Union in the construction of shelterbelts, and successively established shelter forests in western Yunnan, eastern Henan, western northeast, eastern Inner Mongolia, and northern Shaanxi to prevent natural disasters. Among the larger ones are the Northeast and Inner Mongolia.
