| 摘 要： | 关于沙漠化成因,存在主要由于人类不合理的经济活动所造成和地球自然营力为主因两种认识。本文分析认为气候的恶化、生物退化、天然降水和地下水的缺乏是导致沙漠化主要因素,而导致上述自然条件的恶化主要制导因素是地球排气作用、区域低大地热流、地壳运动和油气的微渗漏。

| Abstract: | Abatract: About the cause mechanism of desertification,there are two different of theories at present time.One is about theunreasonable economic activities,the other is the natural agent of the earth.This paper considers that deterioration ofclimate,degradation of creature,precipitation and the shortage of groundwater are the main reason of the mechanism ofdesertification.What leads to these deterioration of natural condition mentioned about? The main control factors are the earthout-gassing,the low terrestrial heat flowing,earth crust movement and the micro-leakage of oil and gas. |
