摘    要:对黑龙江省伊春林区的凉水国家级自然保护区的云冷杉林进行了调查。根据pH值、阳离子代换量、营养元素、微生物数量及云杉根部着生小斑块的大小等,分析了黑龙江省东部山区谷地云冷杉林的衰退原因。结果表明:土壤pH值与云杉死亡没有明显关系;土壤阳离子代换量低是云杉死亡的一个因素;云杉衰退与营养元素的吸收及微生物数量无明显关系;云杉的生长与根部着生小斑块的大小存在密切的相关关系,斑块越大,云杉长势越好,生存周期也更长。

关 键 词:黑龙江省东部山区  谷地云冷杉林  衰退  生境条件

Abstract:An investigation was conducted to the spruce(Picea koraiensis)fir forests in Liangshui Natural Reserve of Yichun Forest region,Heilongjiang Province.The decline mechanism of spruce-fir forests was analysed in terms of soil pH value,cation exchange capacity,nutrient elements,number of microorganism,and patch size in spruce-fir forest in low-lying land.Result shows that there is no closely relationship between soil pH and spruce death.However,the low cation exchange capability is one of the reasons to result in spruce death.No closely relationships were found between nutrient absorption,number of microorganism and spruce decline,while a closely relationship between spruce growth and patch size was found,namely,the spruce located in larger size of patch grows better,and its living period is also longer.
Keywords:Eastern mountain area of Heilongjiang Province  Spruce-fir forest in low-lying lands  Decline  Habitats
