摘要
[目的]研究气温和降雨量对高寒草甸不同功能群植物产草量的影响。[方法]选择典型的高寒草甸为研究对象,通过对1995~2004年气温和降雨量变化的分析,对不同功能群产草量的影响进行了研究。[结果]气温和降雨量对禾本科功能群植物的产草量的影响较大,相关性均达到极显著水平;降雨量对莎草科产草量影响较大且相关性达到显著水平。[结论]不同植物个体对气温和降雨量的反应不同。该研究结果可为草地生态学研究提供理论依据。
Abstract
[ Objective] To research the effects of temperature and precipitation on grass yield of different plant functional groups in alpine meadow. [ Method] With typical alpine meadow as the research object, we analyzed the temperature and precipitation changes from 1995 to 2004, and researched the effects on grass yield of different plant functional groups. [Result] Temperature and precipitation had relatively great impacts on the grass yield of Gramineae functional group;the correlation reached extremely significant level. Precipitation had relatively great impacts on Cyperaceae yield, and the correlation reached significant level. [ Conclusion] Different plants have different reaction to temperature and precipitation. This research provides theoretical foundation for the research on grassland ecology.
