木材腐朽真菌是森林生态系统的重要组成部分，但该类真菌在森林生态系统的物种多样性维持机制、空间分布格局及其成因、真菌群落组成的动态变化及其功能目前还不清楚。本项目拟主要依托我国温带森林生物多样性监测网络，系统地研究我国温带森林中木材腐朽真菌的空间格局和群落动态变化，通过研究真菌种间和种内关系揭示该类真菌在森林生态系统中的物种多样性维持机制；应用种面积关系模型和环境因子的回归分析，明确木腐真菌的空间分布格局及其主要成因；借助高通量测序和CCA、NMDS等排序手段研究倒木不同腐烂阶段的木腐真菌群落动态变化和主要影响因素，并分析真菌主要功能群和倒木理化特征的关系，揭示木腐真菌在森林生态系统物质循环中的关键作用。研究结果将对我国温带地区的木腐真菌空间分布格局有一个全面认识，为保护这一森林生态系统的重要类群提供理论依据；并为深入研究森林生态系统不同生物类群之间的相互作用以及物质循环奠定理论基础。

For wood decomposition are a decisive process in nutrient recycling, soil formation and the carbon budget of forest ecosystem, wood-decaying fungi have been the key component of forest ecosystem due to their ability of degradation of wood, promoting the nutrient cycling in environments. But the fungal spatial distribution patterns and community dynamics changes during the wood-decaying progress are not clear yet. This project will study the fungal spatial distribution patterns and community dynamic changes in temperate forest,China. On the basis of fungal spatial associations of intra- and inter-species, the support mechanism of fungal species diversity in the forest will be analyzed. The species-area relationships of wood-decaying fungi and regression analysis of environmental factor will help to find the spatial distribution patterns and its forming reasons. High-throughput sequencing and CCA, NMDS ordinations will promote to show the fungal community dynamic and the main influencing factors.Further, it will contribute to understand the relationships of major fungal functional groups and the physicochemical property of wood.The ecological function mechanism of wood-decaying fungi during the course of wood decomposition will be realized.The results will show us a clear and total view about the spatial distributon patterns of wood-decaying fungi in the temperater forest in China which help to protect these fungi better. Morever, it promote to study the interaction of different organisms and material cycling in the forest ecosystem.
