摘　　要：以四川省雅安地区的水竹为研究对象,对该地区开花和未开花水竹林内的发笋和幼竹生长特性进行记录分析,并对其高生长与小生境气象因子包括日最高气温、最低气温、同期空气湿度以及地表及地下15 cm处日最高和最低气温分别进行了Logitis模型拟合分析。结果表明:开花对水竹发笋、成竹以及高生长具有显著影响,其生长能力因开花而显著降低;低温包括日最低气温以及地下15 cm处最低地温对于开花与未开花水竹发笋均有显著影响,而日最高气温、空气湿度则不具有统计学意义。The bamboo PhyUostachys heteroclada Oliver blossomed in 2005 in Ya＇an district, Sichuan Province. The grow- ing characteristics of bamboo shoot in blossoming and non-blossoming bamboo forest were surveyed, the relationship be- tween the environment factors including air temperature, ground temperature , humidity and bamboo high-growth were ana- layzed. The results showed that blossoming exerted significant effect on bamboo shoots and growth, the viability was ob- viously reduced due to blossoming, and low temperature including the daily minimum temperatures and the daily minimum temperatures of 15 cm underground all significantly affected on bamboo shoots in both blossoming and non-blossoming bam- boo forest, although the daily maximum temperature, humidity didn＇ t exert statistical significance on this bamboo shoots.
