| 摘 要： | 从系统论的角度,采用系统研究方法对沙漠化的成因及其发展过程加以剖析,认为只有通过发展社会经济和生产力,使人类在合理的社会制度、经济政策和先进的生产方式指导下,发挥主观能动性,协调干旱区的人地关系,优化人地系统诸要素间的结构,保持系统的稳定性,才是解决干旱区沙漠化,实现区域可持续发展的关键之所在。

| Abstract: | Basing on the system theory and making use of the system methods, this paper studies and analyses the process of formation and development of desertification. In fact, desertification is the degenerating process of geographical environment of arid, semi|arid and semi|humid regions. Due to the incoordinating interaction of two inner factors of man|nature system_natural environment and mankind activity, the system deviates from its balance state and the balance can not be rehabilitated by its inner self|organization and feedback mechanism. Finally, all these result in the degeneration of natural elements of man|natural system. Then, the desert landscape takes the place of the sparse woodland rangeland landscape. So we can say that the whole development process of desertification is also an evolution process of man|nature systems structure and function. In the process, the inner elements and outer environments take place the change through the fluxes of energy, matter and information. From the above, we come to the conclusion that the key of resolving desertification of arid regions and achieving regional sustainable development is that mankind should develop social economy and raise productivity firstly, then in the guide of rational social institution, economy policy and progressive productive methods, bring into play the subjective activity, harmonize the relation of man and nature of arid regions, adjust the structure of key elements of man-nature system, keep the stability of the system. |
