| 摘 要： | 对矮牡丹种群生物量的研究表明，矮牡丹地上无性小株的叶、茎干和根系的生物量可分别用m1（DW）＝－0．232＋000771A，ms（DW）＝0．370＋0．18000（D2H1），mr（DW）＝1．54＋0．000338（AH1）来表示象矮牡丹这种似棕榈型生长型的小灌木，植冠面积容易测得，用植冠面积进行叶重的模拟最为准确随年龄的增长，矮牡丹种群各部分生物量都呈指数模式增长

| Abstract: | The biomasses from leaves, stems and roots of Paeonia suffruticosa var. spontanea could be simulated by ml(DW) = -0 .232 0 .00771A, ms(DW) = 0 .370 0. 18000(D2h1 ), mr(DW) = 1 .54 0 .000338(Ah1 ), respectively . This study proved that leaf biomass of P. suffruticosa var. spontanea was precisely simulated using area of plant crown. In fact the area of plant crown of P. suffruticosa var. spontanea could be easilymeasured. The biomass of P. suffruticosa var. spontanea increased with ageing. |
