| 摘 要： | 中国的主要自然生态问题均集中在大西北草原地区，如干旱、水蚀、风蚀、草原退化与荒漠化、盐碱化等。在这里，不是森林而是草被才是理想的生态屏障，它既保护了大西北的土地，又是我国东部精华地区的屏障。从国家战略上应恢复草被、建设新牧区。

| Abstract: | Major natural ecological problems in China are concentrated in the vast grassland areas in Northwestern China, such as. aridity, water erosion, wind erosion, grassland deterioration, desertion and salinization. Here, not forest, but grassy marshland is an ideal ecological protective Screen. It not only protects the land in Northwestern China, but also works as a protective screen for the essence areas in eastern China. From the national strategic point of view, we have to sleep on brushwood and taste gall to construct new pasture and to recover grassland. |
