日本柳杉(Cryptomeria japonica)原产日本。鄂西自治州于50年代初自江西庐山引进种子,作引种试验,60年代在全州进行大面积生产性试验,取得成功,现已大面积推广。据1985年森林资源清查资料,全州柳杉造林1.12×10~4há多,活立木蓄积量1.0×10~5m^3,居于自治州引进树种之首位。一、研究地区的自然环境鄂西自治州位于湖北省西南部,地处东经108°30′—110°31′,北纬29°05′—31°05′。

Japanese cedar was introduced from Japan and grows well in the west part of Hubei province. It has been successfully planted in wide range now. The most suitable sites for this plant are between 800—1500m above sea level. On clay soil and lime stone mountains where Chinese fir is unsuitable, it is advisable to afforestate Japanese cedar which is rapidly growing and high productive in these regions.
