本研究采用模拟增温的方式，探讨了全球气候变暖对阴生植物紫金牛光响应和生物量分配的影响。结果表明：模拟增温显著提高了紫金牛的光补偿点和叶绿素含量，而对最大净光合速、饱和光强和暗呼吸速率等参数无显著影响。模拟增温显著增加了紫金牛的分株数，增幅达25%；但对株高无显著影响。增温还导致紫金牛的总生物量、地上生物量显著增加，根冠比显著降低。其中叶和地上茎的生物量（干重）增幅分别达到35.54%和31.60%，生物量（鲜重）增幅分别达到25.3%和18.9%。

This study focused on the effect of temperature enhancement on light-response of photosynthesis and biomass allocation of Ardisia japonica through the way of simulating temperature enhancement by open-top chamber (OTC) in the field. To compare with the control plot, the results showed that warming significantly increased light compensation and chlorophyll content. However, there was no significant effect on maximum net photosynthetic rate, saturation intensity and dark respiration rate in A. japonica. Warming significantly improved the ramet number of A. japonica with 25%, but no significant effect on plant height. In addition, the warming resulted in the total biomass and aboveground biomass of A. japonica to increase higher than that of the control, but it decreased significantly the root/shoot ratio. And the dry weight and green weight of leaves and stems biomass increased by 35.54%, 31.60%and 25.3%, 18.9%, respectively.
