土壤氧化亚氮产生机理及影响因子的研究

, 2013
大气中N2O浓度持续增长是目前全球关注的焦点问题。土壤N2O产生有多条途径，但是这些途径之间的相对重要性及其与氮肥来源，有机堆肥管理措施和土壤中氧气状况之间的相关性目前尚不清楚。农业上常见的管理措施如施用有机堆肥、氮肥和灌溉能够显著地影响农田土壤N2O排放。为了进一步全面的阐明这些管理措施在不同土壤类型上影响N2O产生排放的机理，我们采集了十种不同类型的农田土壤，进行室内培养实验。研究工作的主要结果如下：1、农田管理措施如施用有机堆肥避免在土壤无机氮本底值含量很低的土壤上进行 ...

Ecological Strategies of the Clonal Plant Potentilla reptans L var. sericophylla

, 2004
本文以匍匐茎草本绢毛匍匐委陵菜(Potentilla reptans L var. sericophylla)为研究对象，基于实验生态学研究方法和野外调查研究了该植物对异质性环境的生态适应对策。 　　对落叶松和油松群林下的绢毛匍匐委陵菜的基株特征和种群特征研究表明：在落叶松林下，绢毛匍匐委陵菜克隆分株具有更大叶面积和更长叶柄；在油松林下，绢毛匍匐委陵菜具有更多的匍匐茎和更多的克隆分株。两个生境中的绢毛匍匐委陵菜形成与其生境相适应的克隆形态和克隆生长特征 ...
