摘　　要：选择≥10℃积温、温暖指数、年降雨量、极端最低气温、无霜期和年均气温6个气象要素,运用模糊数学方法,计算湖北省所有县(市、区)与固定样本(潜江)的相似程度,按照加权和数的大小,结合南方型杨树的生态学特性,将湖北省南方型杨树的引种栽培区划分为最适宜区、适宜区和不适宜区,推荐各区域的适栽品种.A climate regionalization study for introducing southern types of Populus spp. to Hubei Province was carried out by means of Fuzzy mathematics methodology. Six meteorological elements i. e. , accumulated temperature ≥10℃, warmth index, average annual rainfall, the extreme minimum temperature, frost free periods and the average annual temperature were selected to calculate the similarity degree regarding to climate conditions among Qianjiang County, Hubei Province as the fixed sample location and the samples of all counties in the province. According to the sum of the total weighted value, integrated with ecological characteristics of the southern types of Populus spp. , all the areas where southern types of Populus spp. were introduced and planted in Hubei Province were classified into the optimal planting area, the appropriate planting area and the unsuitable planting area. In addition, the right cultivars or clones of southern types of Populus spp. were recommended for each area in Hubei Province.
