摘要:
为了探究草甸草原生态系统的能量固定与分配机制,本研究通过对内蒙古额尔古纳草甸草原中的36种植物进行热值分析,系统探讨了不同功能群(豆科、禾草、杂类草)及不同水分生态类型(旱生、中旱生、旱中生、中生、湿中生)及其植物器官的热值变化规律和能量分配。研究表明:1)36种植物的平均热值为17.31 kJ·g-1,其中植物器官果的平均热值最高,花与叶的平均热值次之,茎的平均热值最低,且均呈现显著差异(P<0.05),在主要科中,豆科植物热值最高,显著高于菊科、毛茛科、石蒜科等,而蔷薇科植物热值则与石蒜科差异不显著。2)在功能群中,豆科热值显著高于禾草与杂类草(P<0.05),其中豆科植物的叶热值显著高于其他器官(P<0.05),禾草的叶热值高于茎,而杂类草则是以花、果热值显著高于茎、叶(P<0.05)。3)在不同水分生态功能群中,植物整株热值之间并未表现出显著差异(P>0.05),除中旱生植物外,其他水分生态功能群均呈现花果热值显著高于茎叶(P<0.05)的结果,水分生态功能群中热值对于器官水平响应显著。4)植物整株热值与碳含量呈显著正相关,表明碳含量是影响植物能量储存的关键基础,植物各器官热值与碳含量同样呈显著正相关,但器官相关性强度不同(花>叶>茎>果),其中花器官相关性最强(r=0.91),果器官呈现相对较低的相关性(r=0.79)。
