摘要
东北地区湿地类型众多.通过分析解剖东北地区湿地的形成与演替机制,揭示了湿地的形成与演替过程中同时承受着自然与人为两种不同性质驱动力的影响,指出人类活动外在驱动力在较小的时空尺度下起着主导作用,如不加以正确引导而盲目开发,势必将导致湿地环境的恶化.
The wetlands in Northeast China are in various types under complicated natural conditions. On the basis of summing up the characteristics, the authors analyze the mechanism of formation and succession of the wetlands. It is revealed that the process of the formation and succession is affected by both natural power and human behaviors. The external force from human activities dominates the process in a relative small time and space scale. Improper exploitation will damage the environment for the wetlands.
