      摘要: 利用桑斯維特(Thonthwaite)的氣候分類法和半峰寬(PWH)計算法,采用Kriging方法和地理信息系統(tǒng)(GIS)等技術(shù),探討了黑龍江省1961-2003年間氣候變化對生態(tài)地理區(qū)域界限及當(dāng)?shù)厣种饕獦浞N分布的影響。結(jié)果表明:在氣溫升高的背景下,黑龍江省溫帶與暖溫帶的熱量界限向北撤并東移,寒溫帶與溫帶的熱量界限則大幅度北撤。同時,分布于大興安嶺的興安落葉松、小興安嶺及東部山地的云冷杉和紅松等樹種的可能分布范圍和最適分布范圍均發(fā)生了北移。其中興安落葉松分布總面積減少6.28萬km2,云冷杉和紅松分布面積均擴(kuò)大1.57萬km2。

      Abstract: By using the Thonthwaite method, peak width at half height method, GIS technique and Kriging method, a comprehensive analysis is performed involving the effects of climate change on boundaries of eco-geographical regions for main forestry species in Heilongjiang Province. The results show that under the conditions of climate warming, the thermal boundary of temperate zone and warm-temperate zone moved towards east and north, and the thermal boundary of cool-temperate zone and temperate zone moved northwards significantly. Meanwhile, all the optimum and potential distributing regions of Larix gmelinii, Spruce fir forest and Pinus koraiensis have the tendency of moving northwards. The eco-geographical distributing area of Larix gmelinii reduced 6.28×104 km2, and on the contrary, those of Spruce fir forest and Pinus koraiensis increased 1.57×104 km2, respectively.
