Abstract: With the contrast material from 15 olive-producing sites of foreign countries,the olive vernalization days,damage temperature friquencies,damage index,ect.were studied in 15 olive planting sites in China,a model describing the thermal characteristic in the olive vernanization period was established.The result shows:Although the thermal model of the olive vernabization period in Chinese olive planting sites is different from that of the check sites,the thermal adaptability is quite to that of the check sites;spring freeza is the most important temperature factor that limits China's olive production;damage index plays a decisive role to differentiate the olive thermal adaptability of Chinese Olive planting regions;selecting varieties with early mature and resistance to frigidity is a significant method for the olive developing in China.In addition, the potential region for the olive growing in China is also discussed.
