舜王坪山地草甸群落生产力及优势种生产力对凋落物的影响内容摘要本研究以山西历山舜王坪山地草甸群落生产力及优势种橐吾（Ligularia sibirica）、早熟禾（Poa annua）和地榆（Sanguisorba officinalis）生产力为研究对象，通过对群落生产力与凋落物生物量、优势种生产力与凋落物生物量关系的分析，结果显示： （1）群落生产力未对凋落物产生影响。（2）优势种生产力未对凋落物的产生影响【关键词】 群落生产力 凋落物生物量 优势种生产力 凋落物The Productivity of Meadow Community and the Productivity of Dominant Species to Litter in Shunwangping Mountain AreAbstractIn this study, Ligularia sibirica, Poa annua and Sanguisorba officinalis were used to study the relationship between community productivity and litter biomass, dominant species productivity and litter biomass in Shunwangping Mountain, Lishan, Shanxi Province. The results showed that: (1) Most community productivity was related to litter biomass. Litter had no significant effect. (2) The productivity of dominant species had no effect on litter【Key words】community productivity Litter biomass Productivity of dominant species Litter fall目 录1 立题依据及研究内容..............................11.1 研究的背景和意义.............................................11.2 国内外研究现状...............................................11.3 主要研究内容.................................................12 研究方法........................................12.1 研究区概况...................................................12.2 样方调查.....................................................22.3 群落生产力测定方法...........................................22.4 优势种生产力测定方法.........................................22.5 凋落物生物量测定方法.........................................22.6 统计分析方法.................................................23 研究结果........................................23.1 群落生产力对调落物生物量的影响..........................
