摘  要:
从大青杨自然分布区按纬度梯度选择10个种源,在哈尔滨、帽儿山、海林3个地点营造种源试验林,分析了各试验点大青杨树高、胸径与各种源地地理、气候因子之间的关系。结果表明,不同种源大青杨树高、胸径基本上表现出与各种源地年均温、1月均温、7月均温、≥10℃积温、无霜期、年均降水量、年均蒸发量呈正相关关系,有些因子达到显著甚至极显著水平;大青杨生长量与各种源地经度、等效纬度基本上呈负相关关系,表现最好的种源地位于中高经度中高纬度地区。

摘  要:
Selecting 10 sources in Populus ussuriensis Kom. natural distribution area by latitude gradient,creating provenance experimental forest in Harbin,Maoershan,Hailin,correlation between test point Populus ussuriensis Kom. height,diameter and geographical,climatic factors were analyzed: different provenances Populus ussuriensis Kom. height,diameter essentially exhibit a variety of sources with an average annual temperature,average temperature in January,July mean temperature,≥10 ℃ accumulated temperature,frost-free period,average annual rainfall,the average annual evaporation is positively correlated,some factors are significant even extremely significant; Populus ussuriensis Kom. growth amount basically presents negative correlation with sources longitude,equivalent latitude,the best provenances locate in high longitude and high latitude area.
