摘要
荒漠是指覆盖在地表的沙漠化土地。是由人类不合理的经济活动所造成。它生成于地质时期,发展在人类各个历史时期。人类必须吸取历史教训,尊重自然规律,才能遏止荒漠化发展的势头。
Desert refers to desertization land on the surface of the earth. Human irrational activities for economic interest lead to more expansion of desert and disappearance of a lot of grass land. Desert is originated from the geology period and developed in each of human historical periods. Only taking historical lessens and abiding by natural laws can human beings stop the desertization tendency.
