舜王坪山地草甸土壤水分对群落优势种生产力的影响内容摘要本研究以山西历山舜王坪山地草甸优势种橐吾(Ligularia sibirica)、早熟禾(Poa annua)和地榆(Sanguisorba officinalis)为研究对象,通过对土壤水分与优势种生产力关系的分析,发现土壤水分仅对优势种地榆的相对生物量产生影响,而对优势种橐吾和早熟禾的生物量和相对生物量未产生影响
表明土壤水分会对当地生态系统优势种产生一定的影响,但这种作用受群落内其他物种的影响
同时,土壤水分的影响也受优势种种类的影响

Soil moisture was found to have an effect only on the relative biomass of dominant cultivar elm, and on the biomass and relative biomass of dominant cultivar ligularia and precocity
It is shown that soil water will have so
