摘要/Abstract

摘要： 气候变化导致生态系统生物多样性丧失，进而影响生态系统服务功能及其稳定性。在生物多样性与生态系统功能关系的研究当中，植物群落功能群多样性更能推动生态系统的运转。本研究利用为期两年的植物功能群去除实验研究短期(2a)植物功能群丧失对生态系统中群落生物量及土壤理化性质的影响。结果表明，与对照相比，短期(2a)去除莎草科植物功能群以及去除全部植物后，地上生物量显著降低(P＜0.05)，而地下生物量均无显著变化。与对照相比，短期(2a)不同植物功能群去除后土壤pH值均上升但差异不显著，土壤含水量均无显著变化，而土壤铵态氮、速效磷及速效钾含量显著降低(P＜0.05)。研究表明，短期内优势功能群丧失对群落地上生物量存在显著负效应。优势功能群对其他功能群丧失后生物量的补偿作用也更强。土壤含水量的响应可能存在滞后效应，土壤速效养分对植物功能群丧失响应更为敏感。

Abstract: The loss of species due to climate change has profoundly affected ecosystem stability. Therefore,understanding how biodiversity loss affects ecosystem properties can provide valuable information for ecosystem stability management. In this study,the experiment of plant functional group removal for a short-term (2 a) was conducted to study the effects of the different removals on community biomass and soil properties in a Carex tibetikobresia meadow. The results showed that the aboveground biomass decreased significantly (P＜0.05),but belowground biomass changed insignificantly in the different plant functional group removal treatments. Soil properties also changed under the different plant functional group removal treatments,among which,soil pH value increase insignificantly,soil water content also changed insignificantly,and some soil available nutrients decreased significantly(P<0.05). In conclusion,the loss of dominant functional groups of Sedge plants had a significant negative effect on aboveground biomass in the short-term (2a),and the functional group had a compensatory effect on community biomass after the loss of other functional groups. There might be a lag effect of soil water content in response to plant functional groups loss,while some soil available nutrients are more sensitive to the loss in the short term.
