摘　　要：淡竹(Phyllostachys glauca)是山东地区的主要栽培竹种。文章以日照海滨国家森林公园、泰安大津口和泰安罗汉崖3种不同立地条件的淡竹林为研究对象,对影响其生长的主要因子进行调查分析。结果表明:3种立地条件的淡竹林中,以日照国家森林公园的淡竹生长表现最优,其次为泰安大津口的淡竹林,泰安罗汉崖的淡竹林生长表现最差。对不同水分条件下的淡竹林研究发现,土壤含水率小于7%时,淡竹叶绿素含量大幅下降,土壤含水率在13%左右时,最适宜淡竹发笋。土壤水分是影响淡竹出笋、退笋以及成竹生长的主要影响因子,也是影响淡竹产量的重要立地因子。Phyllostachys glauca is a cultivated bamboo species preferred in Shandong.This paper investigates and analyzes the main factors affecting the growth of Ph.glauca in three different site conditions,i.e.,Rizhao Seashore National Forest Park,Taian Dajinkou and Luohangya.The results show that the bamboo stands in Rizhao National Forest Park have the best performance in growth,followed by Taian Dajinkou,and the bamboo stands in Taian Luohangya is the worst in terms of growth performance.The experiments on Ph.glauca forests under different moisture conditions find that the chlorophyll content of Ph.glauca decreases significantly when the soil moisture content is less than 7%,and the soil moisture content at around 13%creates the best condition for Ph.glauca to shoot.Soil moisture is the main factor affecting the emergence and degradation of Ph.glauca shoots as well as the growth of adult bamboo,and it is also an important site factor that affects the productivity of Ph.glauca.
