摘　　要：本文根据贵州省各地的生态环境、气候特点,利用1971-2005年贵州省80个气象站点的气温数据,罗甸、安龙、册亨等地2008年的气象数据和小油桐冻害调查数据,设计了具有明确物理意义的低温冻害指数(Ja),并同2008年13个样地的实地调查情况进行了对比验证。结果表明,Ja能够较为客观地反应贵州省小油桐的冻害强度。通过分析35年贵州省各站点的Ja值时空变化特征,发现贵州省20世纪70年代初到80年代中期Ja的值偏高,90年代后有下降的趋势,贵州省的南部和东北部部分地区较为适合小油桐安全越冬。In this paper, based on Guizhou province＇ s ecological and climate characteristics, using Guizhou province＇ s 80 weather stations＇ temperture data from 1971 to 2005 and the temperature data and jatropha＇ s freeze injury survey data in 2008 of Luodian, Anlong and Ceheng, the freeze injury index（ Ja） which had clear physical meaning was designed. The result showed that compared to the 13 sample plots field investigation in Luodian and Ceheng, Ja could perform the freeze injury intensity of Jatropha curcas in Guizhou province. Through analyzing the Ja＇ s temporal and spatial variation in Guizhou 35 years, in the early 1970s to the mid-1980s, Ja value was higher, in the 1990s Ja had a downward trend, and the southern and north-eastern part of Guizhou province were more suitable for Jatropha to wintering.
