sandy land in east of the Yellow River in Ningxia; human activities; desertification
宁夏河东沙地在空间上是我国北方农牧交错区最具过渡性地域特征的沙地,近50年来,也一直是国家和自治区生态治理的重点区域。长期以来,有关该沙地为“人造沙漠”的观点支配着该地区的防沙治沙与生态建设工作。最近的研究表明,宁夏河东沙地在明清大规模的垦殖活动之前就已存在,明清以来沙漠化程度的加深则与人类活动有愈来愈密切的相关关系,与湖泊的萎缩和干涸有直接的对应关系。因此,合理的土地利用方式、防止地下水位下降及湖沼湿地的快速消亡是宁夏河东沙地防沙治沙的有效措施。

The sandy land in east of the Yellow River in Ningxia has obvious characteristics of the transitional region of the farming and the pasturing and it is a focus of harnessing ecological environment for both Ningxia and China in the last 50 years. The viewpoint that“this sandy land is a man -made desert”has influenced the work of defending and controlling sand and the work of ecolcgical construction for a long period. Recent researches prove that this sandy land had existed before the large - scale land cultivating in the Ming and the Qing Dynasty. After the Ming and the Qing Dynasty, the speeding - up desertification has close relationship with human activities, lake shrinking and lake drying. There are many effective measures to defend and control the sand in this sandy land : rational way of using the land, preventing the level of the underground water from dropping and averting lakes and marshes from disappearing.
