摘要
土地荒漠化是目前全球面临的重大生态环境问题之一,因此研究土地荒漠化问题就具有迫切的现实需求。通过系统概述辽西北地区土地荒漠化的相关研究进展,明确了辽西北地区生态屏障作用未受到足够地重视,并指出了该区域土地荒漠化研究中存在的问题及未来的研究方向,得出应用景观生态学等理论、方法和3S等技术手段来研究土地荒漠化问题。
Land desertification is one of the great problems of eco-environment in the world. Therefore, study on land desertification is instantly needed. The systematical summary of research progress of land desertification in northwestern Liaoning indicates that we have not paid enough attention to the function of ecological shelter in northwestern Liaoning. It also revealed the problems in the research of land desertification of this region and the direction of the future research. It is educed that the land desertification should be studied by use of the theory, method and technology of landscape ecology and 3S.
