- Abstract
Gutianshan National Nature Reserve ( GNNR) preserves a large expanse of low elevation typical EBLFs. ln order to understand how species composition of evergreen board-leaved forests ( EBLFs) vary al the regional scale and the underlying drivers, we investigated species composition of 29 20 m x 20 m plots in GNNR, and collected data of other 14 typical EBLFs that distributed across subtropical eastern China, then we investigated the species composition difference between 15 typical EBLFs, as well as how geographical and physical environments drove these differences. The results were as follows: ( 1) GNNH EBLFs composed a variety of community types, such as Gastannpsis forest and Cyclobalanopsis forest de. Species composition of GNNR EBLFs was representative in subtropical eastern China. ( 2) Species composition ( r3 diversity) largely differed between EBLFs. Physical environments, instead of geographical distance, was the most in11uential factor of EBLFs species composition. EBLF species composition was the most in11uenced by the minimum temperature of the coldest month ( MTCM). ( 3) Composition of leaf life forms of 15 typical evergreen broad-leaved forests was the most strongly influenced by the minimum temperature of the coldest month ( MTCM), then by the maximum temperature of the coldest month ( MT\VM). These results indicate that habitat filtering is the main driver of the difference of woody plants species composition among eastern typical EBLFs, and suggest cold temperature is the most important determinant of eastern typical EBLFs comm1mities, would provide guidance for conservation and restoration of EBLFs.
