沙区在我国北方分布广泛,据统计,有71.29万平方公里,约占我国陆地面积的7.43％。这些沙区多深处牧区或与之相毗连,其中流动沙丘对于草原畜牧业有相当大的危害性。能否除害兴利,变有害的流沙为有用的草场,我国牧民的治沙实践早已作了肯定的回答。植物治沙所用的植物,因立地条件不同可有许多种,其中细枝岩黄芪就是一种很有发展前途的植物。它在我国干旱沙区分布较广,不但适应性强,能防风固沙,而且也是一种优良的饲用灌木,对于我国沙区的草原建设具有重要的意义。
Sandy areas are widely distributed in northern China. According to statistics, there are 722,900 square kilometers, accounting for 7.43% of China’s land area. Much of these sand areas are adjacent to or adjacent to the pasturing areas, of which mobile sand dunes are quite harmful to animal husbandry in the grasslands. Whether the detriment of the interests of the harmful effects of quicksand is a useful pasture, the practice of pastoralists in our country has long been affirmatively answered. Plants used to control sand plants, because of different site conditions can have many species, of which the prickly ash Astragalus is a promising plant. It is widely distributed in the arid sandy area of our country. It not only has strong adaptability, but also is an excellent forage shrub, which is of great significance to the grassland construction in sandy areas of our country.
