THE IMPROVEMENT OF ALKALINE MEADOW BY ACCUMULATIVE SAND BY WIND IN THE SONGNEN PLAIN

In the Songnen Plain, there are 330,000 ha of alkaline meadow, many sand sources such as fixed dunes, semi-fixed dunes and sand hills, and rich wind force resources as well. Sand has been stopped naturally and Aneurolepidium chinense has grown on alkaline patch of the plain. If we make use of the natural law and set up manmade obstacles in alkaline patches, we can use accumulative sand to cover alkali, improve alkaline meadow, restore Aneurolepidium chinense vegetation to develop animal husbandry.
