摘　　要：通过对樟子松木材变色部位的化学处理及分析认为,樟子松蓝变类型属于微生物变色;室温下,自然和湿润两种状态放置的樟子松木材,随着时间的变化(以2个月为1个时间单位),L*(明度)、a*(变红度)、TW(白度)都有所下降,DE*(总色差)呈上升趋势,而b*(变黄度)分别呈现增强和减弱两种相反方向的变化趋势。This paper has ascertained the stain type of Pinus sylvistris var. mongolica wood according to the chemistry method, and the sort of blue stain of Pinus sylvistris var. mongolica is belong to stain fungi. Under room temperature, brightness L^＊ , red degree α^＊ and white degree TW of larch wood kept by general and wetness reduce with hours, the general color chromatism DE^＊ rises, and yellow degree b^＊ enlarges for the front and weakens for the latter.
