| 摘 要： | 以福建省降香黄檀15个引种区的调查结果为基础,采用因子分析方法对地理气候因子进行分析;采用相关性分析,分析各项生长指标之间及与各气候因子间的相关性;采用欧氏距离、离差平方和法对各引种地地理气候因子和各项生长指标进行聚类分析,根据聚类结果对引种地进行初步区划。结果表明:引种栽培的主导气候因子是年均气温、年日照时数和海拔。保存率、生长量、适应性都与1月平均气温、≥10℃年积温呈显著或极显著正相关;抗寒等级与9、10月相对湿度呈显著的正相关;海拔与降香黄檀各项生长指标都呈负相关关系;除树高外,各项生长指标都与北纬呈负相关。引种区地理气候条件可以区划为3个区,Ⅰ区处于更高纬度地区(25°28'—26°20'),可定为散生区;Ⅱ区纬度较低(在23°28'—25°00'),可定为较适宜区;Ⅲ区为适宜区。

| Abstract: | The paper concerned on the investigation data from 15 Dalbergia odorifera T.Chen introduction regions,studied on the dominant climatic factors and correlation between growth parameters and climate conditions.By relativity analysis,the relativity of different growth index and climate conditions,the geography and climate factors were analysed by the method of F.A.,the results showed that there were three leading factors which could influence introduction;they were the average climate,the hour’s sunshine per year and latitude.The preservation rate,growth amount,adaptability and monthly mean temperature in January and ≥10 ℃ annual accumulated temperature had significantly positive or very significantly positive correlation.The correlation between cold resistance and the monthly mean air relative humidity during September and October had significantly positive correlation;there was a negative correlation between altitude and the growth parameters.Introduction site geographical and climatic conditions could be divided into 3 districts,District Ⅰ was in the higher latitudes(25°28′~26°20′),which could be regarded as less growth area;District II latitude was in the low latitudes(23°28′~25°),which was more appropriate for growth;District III was the suitable area. |
