摘要: 近年来,所开展的有关沙漠化问题的研究工作和防治实践已为该问题的理论深化提供了坚实的基础。本文图就沙漠化过程及其防治措施的生态学原理进行讨论,虽见解肤浅,但望能藉此引起有关专家对此问题的关注和兴趣,以便共同切磋,从中得到有益的帮助。沙漠化,其定义[1]本身就已表明,它属于自然环境--生物--人类社会相互交织作用网络中,并产生于其间关系失调过程中。因而讨论沙漠化生态学原理,须包括沙漠化发生的生态学机理、沙漠化过程的生态学属性、沙漠化程度的生态学计价及沙漠化土地恢复的生态工程等四个方面的内容。

Abstract: In the last few years, scientific research and controlling practices on the problems of desertification strengthened furtherly the concrete theoritical researches on the issues and provided a good foundation for the detail rec g-nization of the importance of the worldwide concerned problem. It is attempted to discuss the ecological principles of desertification process and its rehabilitating measures, and it is expected to evoke a heated discussion and bring relevant scientists' attention and interests on the problem, with the presentation of superficial opinions, and benefit from different viewpoints on the disasters. Definitionally, desertification resides its meaning in the network of alternative interactions amongst natural environment, biology and human society and the desertification is originated in the processes of dislocation of the interrelation among above-mentioned three aspects. The discussion of the ecological principles of desertification deals with a) ecological mechanism of the crigination of desertification; b) ecological property of desertification process; c) ecological evaluation of the developing degree of desertification; and d) ecological engineerings for rehabilitating land desertification.
