内蒙古草原功能多样性与生态系统多功能性关系研究

功能多样性与生态系统功能关系的研究是近年来生态学研究的热点问题之一。本研究以内蒙古中温性草原为研究对象，结合区域植被调查、室内实验与气候因子空间模拟获得各样地植物功能性状、多个生态系统功能与气候因子指标，从而阐明植物功能性状间相互关系以及不同植物功能性状对气候因子响应；揭示物种多样性、功能多样性与单一生态系统功能关系及维持机制；并进一步在明确生态系统各功能间权衡与协同关系的基础上，探究功能多样性与生态系统多功能性间关系及维持机制。在丰富多样性与生态系统功能关系理论研究的同时，为指导我国退化草地恢复和生物多样性保育提供科学依据。

The relationship between functional diversity and ecosystem function has been one of the important research problems in ecology. This study was carried out in the Inner Mongolia temperate grassland. Combined with vegetation survey, laboratory experiment and spatial modeling of climatic factors, plant functional traits, several ecosystem functions and climatic factors were acquired. This study could clarify the relationship between different plant functional traits, and the response of plant functional traits to climatic factors. It was also helpful to reveal the relationships and maintain mechanism between species diversity, functional diversity and single ecosystem function. Furthermore, based on the understanding of trade-off and synergy relationship between different ecosystem functions, it could explore the relationships and maintain mechanism between functional diversity and ecosystem multifunctionality. The study is expected to enrich the theory study of biodiversity – ecosystem function relationship. It also provided scientific support for guidance of degraded grassland restoration and biodiversity conservation.
