Biomass allocation of boreal trees in response to climate and soil interactions

我的研究计划的总体目标是更好地了解树木生长和碳积累与土壤和气候在北方混交林。特别是，拟议的研究项目将研究树木如何将生物量分配给根、叶和茎，以及这种生物量分配如何因土壤、气候而异，最重要的是，它们之间的相互作用。通过研究树木如何与资源相关地生长，可以更可靠地预测不同气候条件下的未来生长。具体的研究项目将审查不同的尺度（从微型场地到景观）和物种生物量分配对气候和土壤相互作用的反应。目标1将解决颤抖的白杨在景观中的生物量分配，目标2将研究在杰克松的资源可用性和生物量分配的站点水平的空间格局，目标3将集中在生物量分配的少年白色云杉实验操作的资源条件。拟议的研究将有助于确保林地的可持续性，解决森林管理、生长模式和不同立地类型树木生物量分配方面的严重不确定性。具体而言，这项研究将改善特定地点造林工具的应用，更好地估计森林中的碳积累，并帮助制定适当的气候适应计划。

The overarching goal of my research program is to better understand tree growth and carbon accumulation in relation to soil and climate in the boreal mixedwood forest. In particular, the proposed research projects will study how trees allocate biomass to roots, leaves and stems and how this biomass allocation varies by soil, climate and most importantly, their interactions. By studying how trees grow in relation to resources, more reliable predictions of future growth under different climatic conditions will be possible. Specific research projects will examine different scales (ranging from microsite to landscape) and species biomass allocation responses to climate and soil interactions. Objective 1 will address biomass allocation of trembling aspen across the landscape, Objective 2 will examine the site level spatial patterns of resource availability and biomass allocation in jack pine, and Objective 3 will focus on biomass allocation of juvenile white spruce to experimentally manipulated resource conditions. The proposed research will help ensure the sustainability of forest lands by addressing a critical uncertainty in forest management, growth patterns and biomass allocation of trees on different site types. Specifically, this research will improve the application of site specific silvicultural tools, allow for better estimates of carbon accumulation in forests, and aid in the development of appropriate climate adaptation programs.
