| 摘 要： | 通过对两种不同人工林个体生长规律的研究,从树高、胸径、材积三方面初步揭示了华北落叶松(Laris gmelini)和杨树(Populus spp.)的个体生长发育规律,并分析其生物量分布特征,结果表明:杨树的高生长速生期比落叶松早;落叶松林缘树木的数量成熟年比林地中心的树木晚达到;杨树在26 a间未达到数量成熟年;杨树的林缘树木不论胸径、树高和材积生长量均比林中心的高,而落叶松则相反。初步阐明落叶松与杨树对生境条件的适应特征,确定了华北落叶松与杨树的数量成熟年,为人工林的经营和管理奠定坚实基础。 |
| 关 键 词： | 华北落叶松 杨树 人工林 生长规律 生物量 |

| Abstract: | The growth and development patterns of the individuals and biomass distribution of Laris gmelini and Populus spp were studied.The results showed that: Populus sp's high growth livings period is earlier than Laris gmelini's;the Laris gmelini edge's age of quantitative maturity is later than the Laris gmelini center's;26a Populus spp does not attain age of quantitative maturity;the Populus spp edge's DBH,height and tree volume increment is higher than Populus spp center's,but the Laris gmelini 's increment is contrary.The adaptation features of the Laris gmelini and Populus spp in the conditions of their own habitat was clarified,the mature year of the Laris gmelini and Populus spp was determined to fullly use the productivity of land and make sure obtaining the largest production of timber every year,to lay a solid foundation for the operation and management of plantations. |
| Keywords: | Laris gmelini Populus spp plantations growth rules biomass |
