EDITOR'S NOTE
The water birds wintering in Lhunzhub are peculiar to the many wetlands subject to special protection in Tibet. With a view to preventing overspending and destroying the hilly areas and the grasslands, the State has been working hard to seek protection of the wetlands, and the Forestry Bureau of Lhunzhub County seeks to control soil erosion by planting trees and gross. The problem is that the lacul.farmers are still ploughing the.fields deeper and deeper so as to increase their grain output, which endangers the living conditians of those water birds that survive by hunting for leftover grain in the fields, and the black-necked cranes especially are now on the verge of extinction. 相似文献
