中国沙漠化过程中人文作用研究进展

Research Advances of Human Effect on Desertification in China

沙漠化过程中的人文作用研究是沙漠化的重要研究领域,是沙漠科学体系的重要组成部分。国内在人文因素在沙漠化过程中的作用、人文活动对沙漠化的作用机理、历史上沙漠化与人文活动关系、沙漠化中的人文作用定量分析研究、人文活动的驱动因子取得了重大进展,沙漠化治理的技术、模式、策略等方面研究也取得了重要成果。本文试图对沙漠化中人文作用研究做简要综述,并展望未来沙漠化人文作用研究。认为未来沙漠化人文作用研究要以人的行为作为研究的主题,结合多个学科综合研究,把更多研究方法应用到这项研究中,同时拓展沙漠化人文作用研究的领域。

Study on human effect is an important field in desertification research, and it＇s also an important part of deseft scientific system. Human activities have active and passive effect on land desertification. Unreasonable human activity accelerates desertification process, but scientific reclamation approach can reverse the process. By now, important progress have been got in research on the effect of human factors to desertification, mechanism of human activity to desertification, the relationship between desertification and human activity in history, quantitative analysis on human effect to desertification, driving factors of human activities. Also, major achievements have been got in technology, mode and approach of desertification control in our country. There are still some problems existed in this research field, such as whether human factor or nature factor plays a more important role in desertification process, the clear mechanism of human activity playing role on desertification need to be solved, the further discussion that population is direct or indirect reason of desertification are going to be conducted. This article tries to give a brief summary of human effect research on desertification, also give an outlook of human effect research on desertification in the future. The human effect should be the main subject of desertification research in the future; this research scope should be extended.
