摘要
草地生态系统既是我国北方众多自然生态系统中的重要组成部分 ,又是我国北疆一座天然的“绿色生态屏障” ,但这一“绿色生态屏障”却遭到了前所未有的干扰和破坏 ,草地生态系统退化的面积、程度和速度都在进一步加剧。天然草地植被的人为干扰和破坏是草地退化的根本因素 ,本文基于此对恢复退化草地植被的生态功能进行初步的讨论 ,进而提出 :草 +草≠草原。
The turf biology system in North China is not only one of the vital factors in the multitudinous nature biology system, but also a native “green biology dick”. Unfortunately, this “green biology dick” is suffering unparalleled interference and destruction. The area,extend and speed of the degradation of turf biology system are still being aggravated. This paper is based on the standpoint that the fundamental factor of the turf biology degradation is the outcome of artificial interference and destruction to the virgin herb,and an elemental discussion is given about how to recover the degrading herb's biology function. Finally, this view is introduced :Grass + Grass≠ Grassland.Nature does its best and is gratuitous.
