甘肃省天然草地植物种质资源潜势分析与保护利用

The potential analysis, protection and application of natural grassland foragegermplasm resource in Gansu

甘肃省地处青藏高原、黄土高原、蒙新高原和西秦岭山地的交汇地带 ,有亚热带、温带、寒温带气候和草丛、草原、草甸、荒漠等草地类型 ,天然草地面积大 ,植物种类组成复杂、数量繁多、种质资源丰富。综合分析甘肃天然草地植物种质资源的利用现状和潜在优势 ,针对种质资源保护利用仍处于初级阶段这一现实 ,提出了进一步开发天然草地种质资源和保护利用的措施 ,以达到维护草地生态平衡和种质资源持续保护利用的目的。

Gansu is located in a mutual zone of Tibetan Plateau, Loess Plateau, Mengxin Plateau and West Qinling Mountains,which makes its climate varies from subtropical, temperate to cold temperate Many types of grasslands such as herbosa, steppe, meadow and desert can be found in this region Large area of natural grassland embraces complicated and plentiful plant species, enriching germplasm resources In this paper, the current application situation and potential advantage of natural grassland forage germplasm resource were analyzed; the measures of germplasm exploitation, protection and application were presented to maintain grassland ecosystem balance and germplasm sustainable utilization
