摘要
根据乌兰布和沙漠全新世风成砂的沉积记录和湖相沉积中风积物的沉积记录 ,认为历史时期以来 ,乌兰布和沙漠风沙活动主要受自然环境变化的制约 ,沙漠化过程也是一个以自然作用为主、人为作用为辅的过程 ,沙漠化防治的基本途径是建立稳定的绿洲生态农业 ,以“绿洲化”防治“沙漠化”
According to the record of sediment of sand blown by the wind in the Holocene,it is stated that Ulanbuh sandy land's activity of sand blown by the wind was restricted by environmental change in historical period,and the basic approach to desertification prevention and control is to build steady oasis ecological agriculture.
