摘　　要：选取地层埋藏条件中可能与花粉保存状态相关的两个物化因子—pH值和温度开展试验,即将现代杨属花粉置于不同pH值梯度的溶液中,并在模拟的地层温度条件下进行不同持续时间的恒温水浴加热。实验结果显示,杨属花粉随所处环境的酸碱度升高,花粉浓度明显降低、破坏程度显著增加,但与加热时间却无明显关系。A simulation experiment on the modem Populus pollen classified by five pH values heated in water bath with the constant temperature through different durations showed that Populus pollen concentration decreased and deconstmction degree increased with the enhancement of acidity and alkalinity. However, no obvious changes in Populus pollen concentration and further deconstmction phenomenon resulted from continuous experimental heating, which could be explained that Populus pollen was easily deconstmcted in heated basic or acid solutions, but there is no distinct relation with the heating time.
