摘　　要：应用Harper的构件生物结构和种群生态学理论,对海子坪天然毛竹种群生长规律进行了系统的研究。结果表明:天然毛竹竹笋出土的持续时间约为50 d左右,以4月5日前后5 d的为出笋高峰;高生长持续51 d左右,遵循"慢—快—慢"的规律,呈Logistic增长,且有明显的昼夜生长节律;地径生长期在竹笋出笋后的21 d基本停止;温度是影响竹笋—幼竹高生长的主要生态因子。According to Harper＇s module and population ecology theory, the growth and rhythm of natural Phyllostachys heterocycla cv. pubescens clonal population were studied. The main results were as follows ： the sprouting period of bamboo shoots lasted about 50 days and before-after 5 days of Apr 5 was the peak phase. The height growth lasted 51 days, following the rules of ＂slow-quick-slow＂,displaying Logistic growth and showing a significant day-night growth rhythm. The growth of basal diameter stoped after the 21th days of the first sprouting. Temperature was main ecological factor infuencing the growth of bamboo shoots-young bamboo.
