摘　　要：全球气候变化背景下,碳减排受到各国政府的关注。有研究表明减排林碳汇可抵消CO2排放,减排林的生长状况受到政府和社会的重视。通过实地调查分析克拉玛依减排林区28个采样点植被数据和50个土样的盐分、养分,研究了地下水、水盐、土壤养分和生物因素对减排林生长状况的影响,结果表明:地下水埋深较浅的林区比地下水埋深较深的林区林分生长状况较好,地下水埋深与减排林生长有很强的相关性;减排林存在最小限制因子,减排林区中部高径比达到218,树形尖削,不利于减排林生长;林区土壤全氮、全磷、全钾、有机质含量和分布与林分的生长状况成正相关关系;以柽柳为主的林分结构(K07样点)生长状况比俄罗斯杨林好,蓄积量分别为4个俄罗斯杨林采样点的2.4、11.5、3.4和2.4倍,水盐也对减排林生长有重要影响;受病虫害和鼠患等生物因素影响的林区林木生长状况不佳。In the background of global climate change,carbon emission reduction is concerned by governments.Research shows that carbon sink of emission reduction forest can offset CO2 emission,governments and society pay more attention to forest growth.By field survey vegetation data of 28 sampling points salt nutrient content of 50 soil samples were analyzed.Effect of underground water,water salt,soil nutrition and biological factor on forest growth were studied.Result shows that： forest stand types with shallow groundwater table is better than that with lower groundwater table,and underground water has great correlation with growth;emission reduction forest has the least limited factor,the ratio of height to diameter was 218.Trees＇ tip are too needle that grow bad;soil total nitrogen,total phosphorus,total potassium and organic matter has correlation with growth condition of all kinds forest stands;K07 forest stand mainly made by Tamarix ramosissima whose stand volume is 2.4,11.5,3.4 and 2.4 times as large as 4 P.russkii are grow better than that of P.russkii;water salt has important effect on growth;the forest trees in the forest region which were damaged by diseases,insect pests rodent infestation can＇t grow well.
