Field experiment on the effects of short-term drought on tropical rain forest ecosystem

在马来西亚沙捞越Lambir Hills国家公园的热带雨林中进行了导致开花诱导的田间实验。我们建立了一个半径为15米的大伞，以防止大部分降雨被目标树根接收。试验结果表明，该方法对人工诱导成花是有效的。同时，通过监测树木水势、树干液流、土壤呼吸和真菌活性的变化，探讨人工干旱的影响。

A field experiment to cause flowering induction was conducted in a tropical rainforest at Lambir Hills National Park, Sarawak, Malaysia. We established a big umbrella with 15m radius to prevent most rainfall to be received by the target tree root. The target trees made flowers by the experiment, and the method seems effective to cause artificial flowering induction. The changes in water potential of trees, sap flow, soil respiration, and fungal activities during the experiment were also monitored to discuss the effect of the artificial drought.
