摘要 本研究通过对贵州省荔波县茂兰喀斯特区内两种专属植物木质部水分与不同水源氢氧稳定同位素的对比分析,应用水分来源模型计算不同水源对植物的贡献比,探讨喀斯特专属植物水分利用的来源,以加深对喀斯特生态系统水分平衡的认识。 The δD and δ18O values of two kinds of proper plant species in the Maolan National Nature Reserve,Libo County,Guizhou Province were measured.The model was applied to calculating plant water source,so as to discuss the distribution of different plant water sources in karst areas,and improve our understanding of water balance in the karst ecosystem.
