云南省核桃主产区气候因子分析

Analysis on the climatic factors of the main producing areas of Juglans sigillata in Yunnan province

利用云南省核桃主产区40个县的11个气候因子数据,分析各项气候因子对云南核桃分布的影响。结果表明,云南核桃对温度和水分要求较高,其中,温度(包括1月均温、7月均温、年均温、≥10℃积温)对云南核桃分布的影响最大,是第1主导因子;水分(包括年降雨量、年均相对湿度)对云南核桃分布的影响较大,是第2主导因子。

The effects of climatic factors on geographical distribution of Juglans sigillata were analyzed based on the datas of the 11 climatic factors of 40 counties in Yunnan province. The results showed that Juglans sigillata had the higher requirement for the water and temperature. The temperature （included July average temperature, January average temperature, annual average tempearture and ≥10℃ accumulated temperature） was the basic dominant factor, the influence of temperature to the distribution of Juglaas sigiUata 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 Juglans sigillata was the second largest.
