摘要:
为了建立植物与环境因子之间的关系，以2个分布较广泛的树种银杏和垂柳为研究对象，通过研究银杏和垂柳功能性状随环境因子的变化，研究其叶性状在环境梯度上的变异性及与环境因子的相关性，探索树木对环境变化的响应机制，以期为研究树木适应未来气候变化提供一定理论基础。结果表明：银杏和垂柳叶功能性状在环境梯度上都存在一定变化。银杏各性状变动幅度约在20%~329%之间，而垂柳变动幅度在16%~308%之间；银杏和垂柳的叶柄长度、栅栏厚度、叶脉厚度和气孔面积与降水量的相关性大于年均温度。高温多雨会降低银杏和垂柳单位面积氮素和磷素的含量，而对二者单位重量氮素和磷素的含量影响差异较大。
Abstract:
In order to establish the relationship between plants and environment,the variability of the leaf traits of G.biloba and S.babylonica in different temperature and rainfall，the relationship between the traits and temperature were studied.Through the research of ?G.biloba and S.babylonica whose leaf traits change with the environment,and the study was useful for the announcing trees adapt in the future climate change.The results showed that the trees leaf traits changed with increasing average annual temperature and rainfall,the minimum change rate of G.biloba leaf traits was 20% and the maximum one was 329%;for S.babylonica,the minimum one was 16% and the maximum one was 308%.The correlations of the petiole,palisade tissue,leaf vein,stomatal area and rainfall were more relevant than the annual average temperature.High temperature and rainfall reduced the content of nitrogen and phosphorus in unit area,and obvious differently effected the content of nitrogen and phosphorus in unit mass.
