摘要

在浑善达克沙地南缘，以围封7年的沙化草地以及围栏外周围不同地段作为研究对象．通过对比分析围栏外不同地段沙化草地土壤种子库特征，并以围栏内草地作对照，就围封草地的“种子岛”效应对周围沙化草地土壤种子库的影响进行了尝试性研究。结果表明：围封草地“种子岛”效应对围栏外近距离处沙化草地土壤种子库具有显著性影响．它能够以围封草地为中心，呈辐射状促进周围沙化草地土壤种子库恢复，且随着距围栏距离的增加。作用逐渐减小．并约在围栏500m外逐渐消失。

Abstract

In the south edge of Hunshandake sand land

the influences of seed source effect ol enclosed grasslana on seed bank around sandy grassland are researched tentatively by contrasting the characteristics of seed bank in different places of sandy grassland out of fence and the grassland which was enclosed for 7 years as contrast. The results show that the seed source effect of enclosed grassland are dramatic on sandy grassland seed bank out of the fence

especially nearly around the fence

and the influences are fade-away gradually out of fence for about 500 meters. In addition

the seed source effect can restore radially the seed bank around sandy grassland.
