Abstract:
OBJECTIVETo study the habitat characteristics for the growth of Atractylodes lancea.
METHODThe leading factors for the growth of A. lancea are determined after stepwise regression, and the limiting factor are determined by field study, literature search,and weather records. The mean values of leading factors and the limiting factors of A. lancea for 30 years were applied to do spatial interpolation using IDIRIEIW softwares. An overlay was prerformed using data obtained in Mt. Maoshan and the general habitat of A. Iancea.
RESULTIt was found that precipitation is one of the dominant climate factors that affects the quality of A. lancea. High temperature was one of the limiting factor which influences the living of A. lancea. The best habitat was determined to be: annual mean temperature more than 15 degrees C, monthly mean minimum temperature between - 2- -1 degrees C, monthly mean maximum temperature about 32 degrees C, lowest tolerable temperature - 17- -15 degrees C, drought season 1 - 2 months, annual mean precipitation between 1000 - 1160 mm.
CONCLUSIONMt. Maoshan was characterized by having high temperature, short drought season and adequate precipitation. The growth of A. Lancea is a result of environmental stress.
