| 摘 要： | 我国半干旱及干旱地区的草地资源分布广,面积大,类型多样,其主要特征是草地生产力地区间、年度间差异很大,且季节间极不平衡。当前由于利用不合理,草地退化、沙漠化严重。今后重点应以草地资源保护和合理利用为主,并创造条件培育改良草地,逐步扩大人工草地的种植面积,以保畜牧业生产稳定、优质、高产的发展。

BRIEF CLASSIFICATIONS,CHARACTERISTCS AND RATIONAL UTILIZATIONS OF THE GRASSLAND RESOURCES IN THE ARID AND SEMIARID REGIONS OF CHINA |
| |
| Abstract: | Grassland resources is rich in China's arid regions and it occuppies an
area of about 6 billion mu. The grassland vegetation which is dominated
by steppe and desert may roughly be classified into 8 primary types. The-
re are apparent regional, annual and seasonal differences in productivities
and nutrient compositions of these natural grasslands. In a long period past,
the production level of them has been comparatively lower due to their
inappropriate use, degradation, desertification and poor management of the
local animal husbandry. From now on a great many measures should be tak-
en to change the present situation. These are some feasible ones suggested
by the author after his careful studies of the existing problems: 1. Proh-
ibiting random reclamation, misgrazing and wilful cutting for fire-wood for
bettering the condition of the degraded areas or conversing the desertified
farming areas into pasture ones;2. Determining the number of animals
grazed in accordance with the grass quantity and condition for a rational
utilization; 3. Constructiog the artificial grasslands and preventing the ha-
zards of rats and hares. |
