森林群落竞争研究述评

Review of Forest Communities Competition

随着全球变暖以及低碳经济的兴起,森林生态研究已成为当前全球变化与可持续发展研究中的热点问题。森林群落种内种间竞争是森林生态研究中的主要方向之一。当前森林群落种内种间竞争研究的内容主要包括资源因素的竞争机理研究,森林种间竞争强度模型、作用与结果的测量等。主要的研究模型有Hegyi的单木竞争指数模型、单木竞争指数的改进模型和Lotka-Volterra竞争模型等。目前森林群落种间竞争研究中存在的问题主要是森林群落种间竞争研究以模拟的方法居多,但由于受到模型自身特点的限制,在森林群落种间竞争研究中存在较大的不确定性。森林群落种间竞争的未来研究将主要集中在竞争中的根系作用,根系的水分竞争,气候变化对竞争的影响等方面。

With the rise of global warming and low-carbon economy,the forest ecosystem research has become a hot issue in current global change and sustainable development research.Forest communities of intraspecific and interspecific competition is one of the main directions in the study of forest ecosystems.The current contents of the forest communities in the study of intraspecific and interspecific competition including competition mechanism of resource factors,forest interspecific competition intensity model,the role and results of measurement.The main model the Hegyi the single tree competition index model,improved model of the single-tree competition index and the Lotka-Volterra competition model.The problems that exist in the forest communities in interspecific competition between forest communities to the majority of the simulation method,but due to the restrictions of the model itself,there is a big uncertainty in the study of competition among forest communities.Competition among forest communities in the future research will focus primarily on the role of roots in the competition,root water competition,climate change impact on competition and other aspects.
