Abstract
The spatial patterns of upper and lower limit of Castanea mollissima Bl.,C.seguinii Dode and C.henryi(Skan)Rehd.et Wils.were analyzed based on geostatistics method and the interpolation maps of there spatial distribution were drawn.The altitude at the upper and lower limit of C.mollisssima and C.seguinii rise gradually from east to west in their distribution ranges,This trend is quite clear in their western distribution region.That of C.henryi rises from southeast to northwest.The change in the altitudinal ranges is smaller than that of the former two species.Generally,spatial distribution patterns of all three species are correspondent to macro-topography of China.Error analysis shows that the interpolation values are coincided closely with the observed values.The estimated errors are less than 4 percent for C.seguinii,6 percent for C.henryi，and 20 percent for C.mollisssima,which are mainly planted by human.The results suggest that geostatistics method can forcast the distribution patterns of natural species.However,the species affected by human is not fit well because of those regulations disturbance from human.关键词
