摘要
土地盐碱化、沙漠化和草原退化,是干旱内陆盆地主要环境灾害。本文从环境灾害地质作用出发,论述了环境灾害的发生演变历史过程及其发展趋势。指出人类经济活动所诱生的灾害地质作用,是加速内陆盆地大环境恶化的主导因索,从而预断,社会经济发展建设对自然资源深化开发利用,将导致环境地质灾害日益强烈,如不采取妥善保护措施,绿洲将被盐碱更替:草原将被沙漠侵没!为此,提出一些防治对策。
The land salinization and desertization and grass-land dege-neration are mainly environment disaster of arid continental basin.According to environment disaster geology agency, this Paper des-cribes the origination development history process of environmentdisaster and its development trend, also shows that disaster geologyagent caused by human productive action is mainly factor to acce-lerate deterioration of continenal basin large environment. Then,We predict that the environment geology disaster will daily increa-se,as the natural resources are explosively. exploited. If the treat-ments of environment protection are not used, the limited green-sward will be alternated by salinized land, the green grass-landwill be captured by desert. Therefore, the author proposed to pro-tect policy of environment geology disaster.
