Due　to　the　complex　coupling　between　phenology　and　climatic　factors,　the　influence　mechanism　of　climate,　especially　preseason　temperature　and　preseason　precipitation,　on　vegetation　phenology　is　still　unclear.　In　the　present　study,　we　explored　the　long-term　trends　of　phenological　parameters　of　different　vegetation　types　in　China　north　of　30　N　from　1982　to　2014　and　their　comprehensive　responses　to　preseason　temperature　and　precipitation.　Simultaneously,　annual　double-season　phenological　stages　were　considered.　Results　show　that　the　satellite-based　phenological　data　were　corresponding　with　the　ground-based　phenological　data.　Our　analyses　confirmed　that　the　preseason　temperature　has　a　strong　controlling　effect　on　vegetation　phenology.　The　start　date　of　the　growing　season　(SOS)　had　a　significant　advanced　trend　for　13.5%　of　the　study　area,　and　the　end　date　of　the　growing　season　(EOS)　showed　a　significant　delayed　trend　for　23.1%　of　the　study　area.　The　impact　of　preseason　precipitation　on　EOS　was　overall　stronger　than　that　on　SOS,　and　different　vegetation　types　had　different　responses.　Compared　with　other　vegetation　types,　SOS　and　EOS　of　crops　were　greatly　affected　by　human　activities　while　the　preseason　precipitation　had　less　impact.　This　study　will　help　us　to　make　a　scientific　decision　to　tackle　global　climate　change　and　regulate　ecological　engineering.　©　2022　by　the　authors.　Licensee　MDPI,　Basel,　Switzerland.
