The results showed that Juglans s igillata had the higher requirement for the water and temperature. The temperature (included J uly average temperature, January average temperature, annual average tempearture and 逸10益 accumulated temperature) was the basic dominant factor, the influence of temperature to the distribution of Juglans sigillata was the largest. The water (included annual rainfall and average relative humidity) was the second leading factor, the influence of water to the distribution of J
