摘    要:对厚荚相思木麻黄混交林、湿地松木麻黄混交林、厚荚相思纯林、湿地松纯林和木麻黄纯林的林分结构和生物量进行研究.结果表明:厚荚相思比木麻黄、湿地松生长更快.厚荚相思木麻黄混交林的生产力最高,林分总蓄积量达到217.17m3·hm-2,总生物量151.85t·hm-2,分别比湿地松木麻黄混交林、厚荚相思纯林、湿地松纯林和木麻黄纯林增加182.19%、40.16%;9.77%、1.98%;248.03%、41.93%;430.98%、188.41%.厚荚相思木麻黄混交林分结构成层性明显,有利于林分生物量的积累和生态防护效能的发挥.因此,可以把厚荚相思木麻黄混交林作为沿海防护林主要造林方式加以推广.

关 键 词:厚荚相思  木麻黄  混交林  林分结构  生物量

Study on the Biomass and Structure of Mixed Forests of Acasia crassicarpa and Casuarina equsetifolia
Abstract:A comparative study was made on the productivity and stand structure among different kinds of mixed forests of A crassicarpa×C equsetifolia,Pelliottii× C equsetifolia,pure forest of A crassicarpa,pure forest of Pelliottii,pure forest of C equsetifoliaThe results showed that the growth of A crassicarpa is faster than that of Pelliottii and C equsetifolia The mixed forests of A crassicarpa and C equsetifolia had highest productivity;its stand stock and biomass was 21717 m3·hm-2,15185 t·hm-2,they increased by 18219%,4016%;977%,198%;24803%,4193%;43098%,18841% respectively as compared with the mixed forests of Pelliottii and C equsetifolia,pure forest of A crassicarpa,pure forest of Pelliottii and pure forest of C equsetifoliaThe mixed forest of A crassicarpa and C equsetifolia has more rational structure,its stand structure would enable the mixed forest to yield more outturn and biomass,and amplify function of protection The mixed forests of A crassicarpa and C equsetifolia would be applied as main forest method in coastal protection forest
