摘　　要：泥石流灾害后,区域植被生态环境将遭受严重破坏。为了预防土地荒漠化和水土流失,需要监测被泥石流破坏区域的植被生态环境恢复情况。文章在分析河南省泥石流概况和发育特征的基础上,利用无人机遥感监测技术输出区域影像图,获取植被生态环境数据源。采用线性回归方程式计算覆盖度线性倾向,根据植被覆盖度的分布变化、年际变化等,完成植被生态环境恢复遥感监测。经验证:该方法可以有效监测泥石流灾害后植被生态环境的恢复情况。After the debris flow disaster,the regional vegetation ecological environment will suffer serious damage.In order to prevent land desertification and soil erosion,it is necessary to monitor the restoration of vegetation ecological environment in areas damaged by mudslides.Based on the analysis of the general situation and development characteristics of debris flow in Henan Province,this paper uses UAV remote sensing monitoring technology to output regional image maps and obtain the data source of vegetation ecological environment.Linear regression equation is used to calculate the linear tendency of coverage,and remote sensing monitoring of vegetation ecological environment restoration is completed according to the distribution change and inter-annual change of vegetation coverage.It is verified that this method can effectively monitor the restoration of vegetation ecological environment after debris flow disaster.
