摘要
土地资源与地质灾害都有双重属性。地球表层系统的演变、自然环境的变化和人类社会活动是土地资源与地质灾害形成与变化的双重原因。近年来 ,一方面自然变异加剧和人类过量开发利用土地资源导致地质灾害严重 ;另一方面严重的地质灾害又会对土地资源进一步造成破坏 ,由此产生的恶性循环已成为社会经济可持续发展的突出问题。由于自然变异是不以人类的意愿为转移的 ,那么 ,顺应自然规律 ,约束并规范人类社会活动范围、消除不良行为是减轻地质灾害、可持续利用土地资源的最佳策略。
There is an interaction between utilizing of land resource and occurrence of geologic hazards. The formation and development of both land resource and geologic hazards are not only caused by the evolution of Earth surface system and of climato-environment, but also are affected by human activities. A series of grave geologic hazards has resulted from irrational and excessive exploit of land resource during last several decades, in reverse, the serious geologic hazards have resulted in great damages to the land resource. This is a vicious circle which will greatly hamper human social and economic sustainablly deve-lopment. Therefore, in order to reduce geologic hazards and to utilize sustainablly land resource, it would be a best choice to control human social and economic activities and to conform to natural law in utilizing land resource based on understanding of regularity of natural environment.
