摘要
依据生态学原理， 对毛竹林种群的含水率、热值、生物量等进行研究． 结果表明： 毛竹秆、枝、叶各组分的平均含水率分别为３９．９５％ 、３３．８１％ 和５０．８１％ ， 热值依次为２０ １００．２３、１９ ８９２．０３ 和１９ ４６０．６２ （ｋＪ／ｋｇ）， 并在这基础上进一步分析了毛竹林种群光能利用率，
According to the ecology,the moisture content,caloric values and biomass of Phyllostachys pubescens were studied in this paper.The results showed that the mean moisture content of stem,branch and leaf of Phyllostachys pubescens were 39 95%,33 81% and 50 91% respectively,and their caloric values were 20 100 23,19 892 03 and 19 460 62,respectively (unit: kJ/kg).Based on these studies,the paper further analyzed the light energy utilization percent of Phyllostachys pubescens population in different stands.Herefore,the paper may provide scientific basis for the management and development of Phyllostachys pubescens.
