【摘要】 利用黑龙江省81个气象站点1961-2003年实测气候资料的平均值,从分析林业气候资源的角度出发,计算了黑龙江省红松、兴安落叶松主要林型气候生产力,分析了近43a来气候生产力趋势变化的空间分布特征。研究表明:小兴安岭伊春林区、黑河地区、牡丹江地区是有利于黑龙江省主要林型生长的重点优势区域;大兴安岭地区中部和南部是主要林型生长的次要优势区域,而且具有较大的增长潜力。更多还原

【Abstract】 Based on the average values of observed meteorological data of 81 stations from 1961 to 2003 in Heilongjiang Province,the climate productivities of Pinus koraiensis and Larix gmelini forests in Heilongjiang Province were calculated.The spatial distribution of the productivity change trends in last 43 years was analyzed.The results showed that Yichun forest region of Xiaoxing’anling,Heihe region and Mudanjiang region were the key dominant regions for main forest types in Heilongjiang Province,while the middle and southern Daxing’anling region was the subordinate dominant regions with an increasing potential on climate productivity.更多还原
