Application of High-Resolution Remote Sensing Technology in Monitoring National Natural Reserves in Hunan Province
[Purposes]This paper studies the application of high-resolution remote sensing technology in national natural reserves,and provides a basis for the supervision and management of natural reserves.[Methods]In this paper,the national natural reserves of Hunan Province were selected as the research ob-ject,and the high-resolution remote sensing data of three years from 2020 to 2022 were screened.The mod-ern high-resolution remote sensing technology was adopted to realize the remote sensing monitoring of the changes of natural reserves in three years,and the transformation of natural and artificial factors was analyzed.[Findings]The results show that there are 1174 changes of forest land resources,grassland resources,wetland resources,houses,roads,mining land and other construction land,with an area of 843.74 hect-ares.Among them,the total resources were damaged 269.10 hectares and 603 plots were damaged;a to-tal of 17.99 hectares of land were restored and controlled,including 22 plots.The net change was 251.11 hectares of resource damage and 625 land parcel changes.[Conclusions]The research results provide im-portant data basis for the supervision and management of natural reserves,which.It has effectively supported and served major national needs such as natural resources supervision and law enforcement,territorial space use control,and natural protection area supervision.
