中亚热北缘杉木人工林生态系统生物量的研究

为了给中亚热带北缘地区杉木人工林的速生丰产提供理论依据，作者对该地区杉木人工林生态系统生物量作了较为详细的研究。该研究以利川市甘溪山国营林场为试验地，通过实测建立了杉木人工林生物量的生长关系式，分析、探讨了不同立地类型杉木各组分生物量的分配动态及林分生物量在生态系统中的变化规律。研究结果表明，杉木各组分生物量分配均存在Ｗ干＞Ｗ根＞Ｗ枝＞Ｗ叶之规律；乔木层生物量占系统总量的８９％以上；不同立地类型生物量的分配及动态存在一定差异。

Study on the Biomass of Chinese Fir Plantation'sEcosystem in the North Edge of Median Sub-tropic

Abstract:in this paper,the growth relationship of the biomass in Chiners fir plantation have been built.. Ananalysis has been made of the distribution and development of every parts biomass on fir in some differenthabitat and the change in ecosystem. The results show that the fir biomass in the following distribution:W W > W > W: The arbor story biomass is 89 % and more in total ecosystem, The distribution anddevelopment of different habitat biomass is differentia. The results provide a basis for the aultuation ofChinese fir plantation.Subject Words: The Chinese fir plantation, Biomass, Habitat,Ecosystem.
