In　order　to　reveal　the　characteristics　of　spatial　distribution　and　dynamic　change　of　the　forest　in　the　Wuyishan　Nature　Reserve　from　2000　to　2019,　the　recently　proposed　shadow-eliminated　vegetation　index　(SEW)　and　the　method　of　Sen+Mann-Kendall　were　used　together　in　this　study.　The　results　show　a　trend　of　＂decreasing　first　and　then　increasing＂　of　vegetation　cover　change　of　the　Reserve　during　the　sub-periods　of　2000-2011　and　2012-2019,　but,　as　a　whole,　the　vegetation　cover　of　the　Reserve　was　improved　during　2000-2019,　with　43.76%　slight　improvement　and　55.18%　significant　improvement,　approximately.
