摘要

    讨论了全球变化及其对我国北方沙区可能影响的三个问题。首先,全球变化是人为因素与自然变化的藕合,不能忽视全球自然变化过程的研究;其次,沙漠的变化主要与气候
干湿变化有关,要注重研究未来增暖伴随的降水变化,预浏土地沙漠化未来发展趁势;第三,要研究土地沙漠化及其逆转对气候的反馈作用。

Abstract

 In this paper , the author discussed three problems concerning the global change and its possible environmental influence. Firstly,the process of global change is under the control of coupling of natural factors and anthropogenic one. At present,natural change,including COZ natural change,has been neglected to some extend. Secondly , the precipitation change synchronizing with future warning would be quite diffierent between sandy lands in northern area of China,and so did the developping tendency of
land desertification. Thirdly , land desertification and its rehabitation , which induce the change of underlying surface,has had feedback to climatic system.
