China　has　been　the　study　area　for　this　paper.　In　this　paper,　we　took　series　of　MODIS　Enhanced　Vegetation　Index　(EVI)　products　from　2001　to　2012　to　create　the　temporal　vegetation　coverage　(TVC)　as　indication　factor　of　vegetation　cover.　Then　we　selected　a　latitudinal　transect　along　the　latitude　30　degrees　N　and　used　the　continuous　wavelet　variance　to　test　the　characteristic　scale　of　vegetation　distribution　with　the　wavelet　coherency　to　detect　the　multi-scale　relationship　between　vegetation　cover　with　the　effect　factors　through　the　continuous　wavelet　transform.　It　was　shown　that:　(1)　The　study　area　is　divided　into　multiple　nested　pattern　levels　which　are　larger　river　effect　pattern,　physiognomy　effect　pattern　and　the　macro　structure　of　Chinese　Three　Gradient　Terrains.　(2)　In　the　scales　of　0-300km,　vegetation　cover　were　greatly　influenced　by　factitious　factors;　In　the　300-600km　scales,　a　major　scale　characteristic,　vegetation　cover　has　been　influenced　by　elevation,　temperature,　land　use/cover　and　factitious　factors,　and　vegetation　heterogeneity　is　greatly　strong　on　this　scale;　In　the　scales　of　600-1,200km,　vegetation　cover　is　intensity　influenced　by　climate　factors.　(3)　Elevation　plays　an　important　role　to　vegetation　cover.　At　low　elevation　area,　vegetation　cover　increases　with　elevation　growth,　while　it　appears　the　reverse　relation　in　high　elevation　area.　In　the　west　area,　the　correlation　between　vegetation　cover　and　precipitation　is　negative,　while　vegetation　cover　and　temperature　presents　a　strong　positive　correlation.　In　the　whole　eastern　area,　this　relationship　is　not　as　strong　as　in　western　area,　and　in　the　mountains　or　hilly　area,　temperature　and　vegetation　cover　has　a　positive　correlation.　(4)　Artificial　factors　show　some　inhibitory　effects　of　vegetation　cover　that　the　vegetation　coverage　is　relatively　poor　in　the　area　with　intensive　human　activities.
