With　the　altitude,　slope,　aspect,　and　Normalized　Difference　Vegetation　Index　(NDVI)　as　the　landscape　variables　of　topography　and　vegetation,　this　paper　studied　the　scale　dependency　of　topography-vegetation　relations　in　Wuyi　Mountain　Nature　Reserve.　Different　scale　variograms　of　topographic　factors　and　NDVI　were　established　by　wavelet　transform,　and　the　correlations　between　the　topographic　factors　and　NDVI　were　analyzed　by　using　wavelet　coefficients.　In　the　study　area,　there　existed　at　least　two　distinct　scale　patterns　of　topographical　factors　and　NDVI.　The　nearly　synchronous　in　scale　domain,　especially　in　small　scale　domain,　suggested　that　there　was　a　tightly-coupled　relationship　between　topographic　factors　and　NDVI.　The　topographyvegetation　relations　were　scale-dependent,　and　the　correlation　coefficients　of　NDVI　and　topographical　factors　were　larger　in　larger　scales　than　in　smaller　scales,　suggesting　that　topographical　factors　played　important　roles　in　controlling　NDVI　patterns　in　larger　scales.　The　relationships　of　NDVI　with　slope　and　aspect　showed　a　large　and　complicated　variation　with　spatial　scale.　This　study　could　help　to　the　understanding　on　the　multi-scale　complicated　correlations　between　topography　and　vegetation　in　the　Reserve,　and　indicated　that　wavelet　transform　was　useful　in　exploring　the　multi-scale　spatial　pattern　of　natural　resources.
