Planning and design of pine forest vegetation and dynamic monitoring method for recovery process in earthquake-stricken areas

Abstract

In order to better monitor and realize the vegetation of the ecosystem after the earthquake, and to provide reference for the rapid recovery of the ecological vegetation system after the earthquake, this paper discusses the vegetation planning and design and the dynamic monitoring method of the damaged vegetation restoration process in the earthquake-stricken areas. Based on the seismic disaster image and field investigation, the pine forest in L province was taken as the research area. The dynamic monitoring model of vegetation restoration process was established by using remote sensing technology. The vegetation restoration of different altitudes, slopes, and slopes was analyzed. The monitoring results show that 68.53% of the vegetation restoration effect is good. Vegetation restoration is mainly affected by altitude and slope gradient but less affected by aspect. The areas with better vegetation restoration are located in the sunny slope below 35° with an altitude of 1000–2000 M. Thus, the effective dynamic monitoring of the pine forest vegetation restoration process after the earthquake is realized.
