Comparative Analysis On The Environmental Changes And Human-land Relationship Between The Western Liaoning And Loess Plateau In Holocene Megathermal

The　global　climatic　is　getting　warmer　and　warmer　because　of　increase　of　green-house　gases　such　as　carbon　dioxide.　Global　warming　can　lead　to　global　environmental　changes　and　it　can　affect　mankind　in　the　future.　Now　these　are　already　important　questions　that　human　must　pay　close　attention　to.　In　order　to　predict　the　environmental　condition　in　the　future　better,a　certain　number　of　scholar　suggests　that　we　should　choose　warm　period　similarity　in　geological　age　as　the　index　which　is　used　to　distinguish　climatic　and　environmental　changes　in　next　century　.　As　the　reagions　whose　environmental　is　severaly　decreased　and　whose　social　economy　is　relatively　fall　behind　,　it　has　important　theoretical　meaning　to　study　its　environmental　changing　process　and　human-land　relationship.Having　the　aid　of　it　,we　can　not　only　predict　the　envrionmental　changes　which　will　appear　supposely　in　the　future　but　also　research　human-land　relationship.　In　this　paper　we　plan　to　renew　environmental　change　and　developing　law　different　time-scale　of　Western　Liaoning　and　Loess　Plateau　when　Holocene　Megathermal　by　climatic　changes　which　is　a　dominant　factor　in　environmental　factors.Then　the　author　probe　into　the　process　of　human-land　relationship　of　the　two　reagions　through　the　major　clue　of　the　process　of　human　developing　course　in　Megathermal　.　At　last　the　author　compares　the　same　and　different　part　of　environmental　chang　and　human-land　relationship　in　Megathermal　between　the　West　of　Liaoning　and　Loess　Plateau　comprehensively　.Through　comparison,we　discover　they　have　huge　samilarity　in　entirely　derection　and　phase　of　evolution.However　they　are　different　in　menifestation　in　some　specific　phase.
