| 摘 要： | 内蒙古四子王旗农牧交错带林地属于干旱、半干旱区的林地，在保护国土、改各生态环境、维护生态平衔、拓宽人类活动空间、优化生存环境质量等方面起到了重要作用；尤其是在生态失衡、环境遭到破坏的荒漠化发生地区，以某种特殊目的营建的农防林、水土保持林、水源涵养林等既是农牧业的人工防护屏障，又是整个农业生态系统的骨架。本文就由于过度放牧、樵采和垦荒等破坏植被后导致的沙化，使林地成为沙源地的演化情况进行探讨。

| Abstract: | The woodland of agropastoral areas of Siziwang Qi in arid and semiarid areas has played an important role in protecting territory, improving ecoenvironment, maintaining ecological balance, broadening human's activity space and optimizing the quality of living environment, and so on. Especially in areas of ecosystem unbalanced and desertification occurring, farmland shelter forest, water and soil conservation forest and headwater forest planted for special purpose are not only the artificial protective screen, but also the framework of whole agricultural ecosystem. In this paper, the evolvement from woodland to sand source has been discussed because of desertification caused by overgrazing, overfelling and overreclamation. |
