In　order　to　explore　the　application　potential　of　unmanned　aerial　vehicle　(UAV)remote　sensing　in　the　verification　of　afforestation　results,　unmanned　aerial　vehicle　(UAV)　remote　sensing　technique　was　used　to　extract　the　parameters　and　the　number　of　tree　well　in　a　cutting　area　of　Jiangle　County,　Fujian　Province.　Phantom　4Pro　UAV　equipped　with　a　digital　camera　was　used　to　obtain　0.01　m　resolution　aerial　images.　DOM,　DSM　and　point　cloud　data　were　acquired　after　pre-processing.　They　were　interpreted　by　artificial　visual　interpretation,　template　matching　method,　circular　Hough　transform,　respectively,　by　which　all　the　parameters　of　tree　well　were　extracted　and　then　analyzed　and　the　applicability　and　classification　accuracy　of　each　method　was　evaluated　in　the　parameters　extraction　of　tree　well　in　afforestation　project.The　correctness　of　tree　well　number　obtained　by　template　matching　was　92.60%.　The　correctness　of　holes　number　obtained　by　circular　Hough　transform　was　95.15%.At　the　same　time,　the　measurement　of　tree　well　width　and　depth　got　a　good　results　with　the　R2of　0.93　and　0.92,　root　mean　square　error　(RMSE)　values　of　1.02　cm　and　1.67　cm.　It　not　only　had　high　precision,　and　the　results　were　consistent　with　template　matching　method,　but　also　extracted　the　width　and　depth　of　tree　well　and　improved　the　processing　speed　of　big　data.Remote　sensing　based　on　UAV　could　be　used　for　number,　width　and　depth　parameters　extraction　of　tree　well.　The　circular　Hough　transform　method　could　get　precision　parameters　of　tree　well,　which　providing　a　technical　plan　for　quality　checking　of　tree　well　and　extending　UAVRS　application　in　afforestation　project.　©　2021,　Chinese　Society　of　Agricultural　Machinery.　All　right　reserved.
