摘要:
在全球气候变暖的背景下,碳排放权成为制约我国经济发展的基础. 我国草地是个巨大的碳库,但大部分草地并未得到合理利用,未能充分发挥其固碳潜力. 因此,探讨合理的草地利用管理方式以提高其碳汇功能,是为我国争取更多碳排放权的有效途径. 以重庆云阳岐山草场为研究对象,进行野外刈割梯度试验(留茬高度6 cm、9 cm、12 cm),探讨刈割对草地补偿生长的影响. 基于一个生长季的研究发现:(1)在轻度和重度刈割处理下,群落地上部分实现了超补偿(P < 0.01),而在中度刈割处理下实现了等补偿(P > 0.05). (2)不同功能群物种对刈割的响应差异很大. 轻度、中度和重度刈割处理下,禾草类的地上生物量(AB)分别提高了20%、18%和 27%,地上部分碳储量(AC)分别提高了21%、19%和25%,普遍实现了超补偿(P < 0.01),这主要与其优势物种鸭茅和黑麦草的超补偿有关;杂类草的AB分别提高了72%、45% 和22%,AC分别提高了71%、46%和22%,也普遍实现了超补偿(P < 0.01);而菊科的AB分别降低了61%、69%和51%,AC分别降低了61%、70%和51%,普遍实现了不足补偿(P < 0.01);轻度和中度刈割使豆科AB分别提高了22% 和22%,AC分别提高了20%和23%,都实现了超补偿(P < 0.01). (3)轻度、中度和重度刈割导致群落根系生物量(RB)下降了9%、10% 和19%,根系碳储量(RC)下降了13%、11%和20%,发生不足补偿(P < 0.01),这主要与在刈割处理下鸭茅和牛尾蒿RB和RC的减少有关. (4)刈割对群落地上部分和根系的总碳储量影响不显著(P > 0.05),但对优势物种总生物量(TB)和总碳储量(TC)的影响差异很大. 在轻度、中度和重度刈割下,黑麦草的TB分别增加了24%、28%和82%,TC分别增加了22%、32%和93%,实现了超补偿(P < 0.01),而菊科优势物种牛尾蒿的TB却分别减少了83%、83%和78%,TC分别减少了83%、84%和78%,普遍了不足补偿(P < 0.01). (5)刈割对生态系统碳交换过程(NEE,GEP,ER)的影响较小,表明短期内刈割对草地的固碳无影响. 本文研究结果表明,短期内轻度刈割能促进草地产量的提高,但对草地的固碳能力无影响;而在刈割管理下,适当补播黑麦草有利于提高我国南方草地的固碳潜力.
Abstract:
In search of a sustainable clipping management system to improve the potential of carbon sequestration in order to win the priority to emit more carbons, four clipping managements of different intensities were experimented during the year 2012 in the Qishan Pasture of northeast Chongqing. We examined the responses of aboveground biomass (AB), aboveground C storage (AC), root biomass (RB), root C storage (RC), total biomass (TB), and total C storage (TC) across different levels of organization (i.e., species, plant functional group and community) as well as the net ecosystem exchange (NEE), ecosystem respiration (ER) and gross ecosystem productivity (GEP). The results demonstrated that 1) under light and heavy clipping intensities, AB of community increased by 32 g m-2 and 27 g m-2 respectively and its AC increased by 13 g m-2 and 9 g m-2, respectively, exhibiting over-compensatory growth. 2) The plant functional groups and their component dominant species responded differently to clipping. For grass, light, middle and heavy clipping treatments all significantly increased AB by 20%, 18% and 27%, and enhanced AC by 21%, 19% and 25% , respectively; for forbs, an increase of 72%, 45% and 22% in AB, and 71%, 46% and 22% in AC was found in the light, middle and heavy clipping treatment, respectively; for Fabaceae, light and middle clipping treatments significantly enhanced AB by 22% and 22%, and AC by 20% and 23%; however, Asteraceae exhibited under-compensation under three clipping intensities, with AB and AC reduced by 51-69% and 51-70%, respectively. 3) Clipping significantly reduced RB and RC, with a decrease of 9%, 10% and 19% in RB and 13%, 11% and 20% in RC found under light, middle and heavy clipping treatments respectively, which was contributed by the decrease in RB and RC of Dactylis glomerata and Artemisia dubia. 4) Though clipping exhibited little effect on TB and TC of community, TB and TC of different dominant species responded to clipping differently. Clipping significantly increased TB and TC of Lolium perenne, but decreased TB and TC of Artemisia dubia. Light, middle and heavy clipping increased TB of Lolium perenne by 24%, 28% and 82% and TC by 22%, 32% and 93%, but reduced TB of Artemisia dubia by 83%, 83% and 78% and TC by 83%, 84% and 78%, respectively. 5) Little difference of NEE, ER and GEP was found among the four different clipping intensity treatments at monthly or seasonal level, indicating that clipping did not affect TC of community. In sum, light clipping probably can enhance the primary productivity of grassland in short term; and planting Lolium perenne can help to improve carbon sequestration of grassland in southern China.
