| 摘 要： | 水域生态系统的动态平衡是多重尺度的生物过程和非生物过程相互影响和作用的结果,动态平衡状态容易受到干扰而破坏.在分析水域生态系统干扰因素的基础上,结合系统组成,从工程角度将水域生态系统划分为4个尺度,即微小尺度、小尺度、中尺度和大尺度,然后对这4个尺度所对应的时间和空间尺度进行了概化,讨论了各尺度之间的关系,说明了时间尺度和空间尺度在生态修复工程中的应用效果.

| Abstract: | The dynamic equilibrium of aquatic ecosystems is the result of the interaction between multi-scale biological process and non-biological process,and it is easy to be disturbed.Based on an analysis of the interference factors and composition of the aquatic ecosystems,the ecosystems were classified into 4 scales from the angle of engineering,i.e.t he micro-scale,the small-scale,the medium-scale,and the macro-scale,and the temporal and spatial scales corresponding to the 4 scales were generalized.Furthermore,the relationships between the different scales were discussed,and the application and effectiveness of the temporal and spatial scales in ecological rehabilitation were introduced. |
