摘要
根据引种的气候相似理论,选取年平均气温、≥10℃积温、绝对最低气温、绝对最高气温、最冷月平均气温、最热月平均气温、年降水量、夏半年降水量(5-8月)、年日照时数9个气候因子作为分析因素,应用欧氏距离模糊相似优先比法划分我国适宜引种太平洋黄松的区域。将全国划分为适宜区、次适宜区、不适宜区。
According to the theory of climatic analogues, nine factors were chosen in the analysis for the introdution of Pinus ponderose var. ponderosa namely annual average temperature,≥10℃ annual accumulated temperature, the minimum temperature, the maximum temperature, average temperature of the coldest month, average temperature of the hottest month,annual precipitation, summer precipitation, annual sunshine hours. The suitable climatic and ecological regions for introducting of P. ponderosa var. ponderosa in China were divided by applying Euclidean fuzzy distance similitude priority ratio. Three regions were divided favorable area, less favorable area, and unfavorable area respectively.
