| 摘 要： | 泥石流灾害对流域植被、土壤、水体等生态环境要素具有极强的破坏作用，快速有效地监测灾害影响区内生态环境的变化对防灾减灾工作有着重要意义。本文选取白龙江流域泥石流灾害为研究对象，利用多期次遥感影像提取了生态因子信息，构建了生态质量评价模型。结果表明，基于时间序列影像的遥感监测能够有效地刻画灾害发生前后的区域生态变迁过程，对地质灾害区的生态监测和修复具有实际应用价值。

| Abstract: | Debris flow disaster has a strong destructive effect on ecological environment factors such as vegetation, soil and water in the basin,then how to quickly and effectively monitor the changes of ecological environment in the disaster-affected area is of great significance for disaster prevention and mitigation. In this paper, we take the debris flow disasters in Bailong River as the research object, extract the information of ecological factors from multi-stage remote sensing images, and construct the ecological quality evaluation model. The results show that the remote sensing monitoring based on time series images can effectively describe the regional ecological change before and after disasters, which has practical application value for the ecological monitoring and restoration of geological disaster areas. |
