灾害生态学——生态学的一个重要发展方向

对灾害生态学有关的基本概念与主要研究内容进行了探讨。认为灾害实际上是一种异常的生态学现象与过程，因此需要从生态学的角度加以研究，特别是要对灾害系统的发生成因、类型、时空分布、发展、危害、预测、控制和灾后恢复等的全过程生态学现象和规律以及相关技术进行研究。同时指出，当今，应围绕重大的全球性环境灾害问题，对其发生与发展的生态学机制与生态学后果，以及减轻、防范这些灾害的关键技术开展研究。

DISASTER ECOLOGY-AN IMPORTANT STUDY FIELD OF ECOLOGY

The basic concepts and study fields of disaster ecology were discussed. The important objectives in disaster ecology were put forward. Actually, most disasters could be regarded as ecological phenomenon and processes, so they should be studied from the viewpoint of ecology, especially for the causes, types, temporal and spatial distribution, occurrence, development, effects, prediction, control and restoration of different kind of disasters. Meanwhile, studies on ecological mechanics and effects, key technologies to control and prevent disasters should be conducted around global eco environmental problems.
