川西亚高山针叶林土壤生态过程的研究

土壤生态过程是川西亚高山针叶林生态系统过程研究中最具挑战性的研究领域，也是森林生态系统功能和过程研究中不可或缺的研究重点。土壤生态过程研究将有助于深入了解森林生态系统功能。目前。有关土壤生态过程的研究主要集中在土壤生物对土壤物理、化学和生物过程的影响以及人类活动干扰对土壤生态过程的影响等方面。但迄今为止，有关川西亚高山针叶林土壤生态过程的研究还处于空白。因此，建议在开展川西针叶林生态过程研究时，应加强以下研究领域的工作：土壤生物多样性的功能重要性及其对土壤过程的影响、土壤与植被的互动、土壤生态过程对气候变化的响应、土壤生态过程中土壤酶系统分异以及土壤过程与针叶林生态系统地上过程的关系等。

Advances in Soil Ecosystem Process of Subalpine Forest in Western Sichuan

Study on soil ecological process is helpful to deeply reveal the function of forest ecosystem, and is one of the most challenging fields in all ecological processes of subalpine coniferous forests. The research in this field focus mainly on effects of soil organisms on soil physical, chemical and biological processes and influences of human activities on the soil ecological processes. There has,however,a lack of information on soil ecological processes of subalpine coniferous forests in western Sichuan. It is suggested that studies on the ecosystem process of the subalpine coniferous forests in western Sichuan should be carried out. The issues such as the functional importance of soil biodiversity and its linkages with other ecosystem processes, interactions between soil and vegetation, responses of soil ecological process on climate change, soil enzyme system differentiation in the soil ecological process, and how to link soil process with plant process etc. are urged.
