我国北方荒漠草原退化研究进展

Research Progress on Degradation of Desert Steppe in Northern China

针对近年来内蒙古地区荒漠草原严重退化的生态问题,文章归纳总结了内蒙古荒漠草原及其退化面积概况,综述了关于内蒙古荒漠草原退化表现及影响因素、荒漠草原退化监测及评价体系以及荒漠草原退化治理对策,并在此基础上分析认为:目前关于荒漠草原退化研究多集中在荒漠草原退化现状、荒漠草原退化影响因素以及退化不同阶段植被及土壤特征等方面,而在荒漠草原退化监测及评价、荒漠草原退化过程机理、荒漠草原生态重建的方法及技术体系方面具有很大改进余地及深入研究价值。

In view of the serious degradation of desert steppe in Inner Mongolia tions of desert steppe have been summarized tern on degradation of desert steppe, as well , the influencing factors of degradati as the countermeasures have been in recent years, the general situa- on, monitoring and evaluation sys- discussed. Based on the analysis, the present research has mainly focused on the present situations and influencing factors of degradation of desert steppe, as well as the features of vegetation and soil in different periods of degradation. The deep researches can be done on monitoring and evaluating the degradation of desert steppe, the mechanism of degradation course of desert steppe, and the method and technology of ecological reconstruction of desert steppe.
