摘　　要：通过对不同混交比例的香椿湿地松混交林与香椿、湿地松纯林的生长比较,并进行成效分析研究。结果表明:香椿与湿地松混交后,不同的混交比例,其生长量不同,在混交比例为1∶2时,香椿湿地松生长量明显提高;在混交比例为1∶1时,香椿的生长量提高,而湿地松的生长量受到影响。香椿湿地松以适当的比例进行混交造林,因种间关系协调,改善了林内的生态环境条件,促进了林木生长,且混交比例在1∶2时,其生长效果佳,是闽东沿海山地理想的一种高产稳定、生态协调的人工针阔混交林类型。Growth for mixed forest of Toona sinensis ＆ Pinus elliottii with different mixed proportion and growth of pure forest of Toona sinensis ＆ Pinus elliottii were compared;their growth effect analysis were studied. Result shows that： growth of mixed forest of Toona sinensis ＆ Pinus elliottii with different mixed proportion is different. Growth of Toona sinensis ＆ Pinus elliottii are significantly improved while mixed ratio being 1： 2 ; growth of Toona sinensis was improved with the mixed ratio being 1 ： 1, and growth of Pinus elliottii was affected. Toona sinensis ＆ Pinus elliottii were mixed with appropriate proportion ; due to the coordinated interspecific interactions, ecological conditions of the forest were improved , and growth of forest stand were promoted;the growth effect was optimal while the mixed ratio is 1： 2;it is a high-yield, steady ＆ ecological harmonious mixed plantation of conifer and broadleaf in coastal mountainous region of eastern Fujian.
