气温、降水对兴安落叶松生长的影响研究

本文通过在大兴安岭根河地区内选取的50株标准木来作为研究材料.搜集其地区的气候资料,挑选出春夏秋冬四个季节各季节的平均气温、最高气温、最低气温和降水量共十六个气候因子,采用相关性分析法,分析胸径和树高的连年生长量与各个气候因子之间的变化关系.结果表明:兴安落叶松生长受春季降水量影响最大,其次是冬季,受秋季影响最低,与夏季降水量无关.受除冬季以外,其他季节的季平均气温的影响最大,其次为最高气温,与最低气温无关(不包括夏季).兴安落叶松生长在冬季受最高气温影响最大,然后是平均气温,与最低气温无关.

In this paper,50 standard trees selected from the genhe river area of the greater khingan mountains were used as research materials.Sixteen climatic factors including average temperature,maximum temperature,minimum temperature and precipitation in the four seasons of spring,summer,autumn and winter were selected by collecting the climatic data of these regions.The results showed that the growth of larch in xingan was most affected by spring precipitation,followed by winter,and was least affected by autumn,which had nothing to do with summer precipitation.Except winter,the seasonal average temperature of other seasons has the greatest influence,followed by the highest temperature,which is unrelated to the lowest temperature(excluding summer).The growth of larch in xingan is most affected by the highest temperature in winter,and then the average temperature,which has nothing to do with the lowest temperature.
