我国草地生态建设与荒漠化防治

The relationship of grassland ecosystem construction and desertification control in China

在我国 ,荒漠化集中发生的区域也正是草地畜牧业的主体分布区域 ,草地退化是荒漠化的主要表现形式。草地生态建设应成为荒漠化防治的中心环节。为适应 2 1世纪加快荒漠化防治、实现区域可持续发展的要求 ,草地生态建设应注重以下问题 :1)草地生态系统与水资源利用的关系 ;2 )荒漠化正逆过程对草地生态系统影响的监测 ;3)草地旅游等非农业开发利用的科学管理 ;4 )抗荒漠化草本植物种类选育。

In China, the most of the grasslands are going to be the desertification areas. The reconstruction of the grassland ecosystem should be the main task in those areas. For the sustainable developing of the areas in the 21 century, the study of the grassland ecosystem should be extended for: 1)the relationship of the grassland ecosystem with the water resource utilization. 2)the desertification resistance mechanism of the herbage species and it’s community. 3)grassland exploring for non agriculture utilization and its effects on the environment. 4)the monitory for the process of grassland degradation.
