闽楠栽培气候区划研究

A Study on Climatic Regionalization of Phoebe bournei

利用中国气象局1971-2000年地面气象数据,应用Gr ADS软件,绘制闽楠年均温、最冷月均温及年降水量气候等单个因子的气候区划图,并将其叠加,形成闽楠气候区划图,气候区划结果表明,闽楠适宜栽培区在北纬24°-30°,东经110°-123°呈长方形分布,包括广西壮族自治区和广东省北部、湖南省中南部,以及江西省和浙江省南部地区和福建中部以北等区域。较适宜栽培区包括浙江省和湖南省北部,安徽省、云南省、广西壮族自治区、广东省和福建省等省南部地区。闽楠年均温最低线以南为潜在引种区,以北地区则为闽楠不适宜引种区。

Based on the ground meteorological data during the period 1971—2000 from the Chinese Meteorological Bureau,using Gr ADS software the zoning maps of single factor climate,such as mean annual temperature,average temperature of January and annual precipitation were drawn. By overlapping these three graphs the climatic zoning map of Phoebe bournei was formed. The most suitable distribution area of this tree is located in the area 24-30 N,110-123 E,including northern Guangxi and Guangdong,south-central Hunan,northeast Jiangxi and Zhejiang and the central asia north of Fujian. The relatively suitable area includes northern Zhejiang and Hunan,southern Anhui,Hubei,Yunnan,Guangdong,Guangxi and Fujian,the area south of the annual mean temperature minimum line is the potential distribution area and north of the line is not suitable.
