项目摘要

An increasing human population and the associated need to produce food in a changing world is one of the greatest challenge facing our generation. It is clear that we need to manage our agricultural systems more judiciously to yield benefits from ecosystem services, including biodiversity conservation, carbon and nutrient cycling and greenhouse gas regulation, along with food production. Grasslands are thought to be a key system for provision of these ecosystem services due to their large global coverage, but also because of their potential as reservoirs of biodiversity and nutrients. For instance, in the UK grasslands cover 36% of the land surface and already hold 32% of the UK soil carbon stock, and if managed correctly they could store even more. The Intergovernmental Panel on Climate Change have identified grassland management as having the greatest potential to sequester additional C if managed correctly, and so grasslands are a key system for climate change mitigation. Here we propose that multiple ecosystem services, such as carbon storage, nutrient retention and reduced greenhouse gas emissions in grassland can be enhanced with management of the diversity and composition of the plant community. The reason for this is that plant species differ greatly in their functional characteristics, or traits, and these differences strongly influence the amount and quality of organic inputs to the soil, which in turn stimulates components of the soil microbial community responsible for soil carbon and nitrogen cycling. Moreover, these differences in traits could change the magnitude and direction of ecosystem services such as from net emission of greenhouse gases, towards mitigation via vegetation management. In this study we will characterise the differing traits of key grassland plant species associated with grassland biodiversity restoration, and test their impact on grassland ecosystem services including emissions of the greenhouse gases carbon dioxide, methane and nitrous oxide, soil microbial activity and nutrient cycling and retention. This will provide the first information on the potential for plant diversity to be utilised to manipulate soil nutrient cycling towards greater carbon and nitrogen storage, and lower greenhouse gas emission.

人口越来越多，在不断变化的世界中生产粮食的相关需求是我们这一代人面临的最大挑战之一。显然，我们需要更加明智地管理我们的农业系统，以从生态系统服务中获得好处，包括生物多样性保护，碳和营养自行车以及粮食生产。由于草原的全球覆盖范围，草原被认为是提供这些生态系统服务的关键系统，而且还因为它们作为生物多样性和养分的潜力。例如，在英国，草原占地36％，已经占英国土壤碳库存的32％，如果正确管理，它们可以存储更多。政府间气候变化的面板已经确定草地管理具有最大的潜力，如果正确管理，则具有隔离C的最大潜力，因此草原是缓解气候变化的关键系统。在这里，我们建议通过管理植物社区的多样性和组成，可以增强多种生态系统服务，例如碳储存，养分保留和减少的草原温室气体排放。这样做的原因是，植物物种在其功能特征或性状上有很大差异，而这些差异强烈影响土壤的有机输入的数量和质量，这又刺激了负责土壤碳和氮气循环的土壤微生物群落的组成部分。此外，这些特征上的差异可能会改变生态系统服务的规模和方向，例如从温室气体的净排放，通过植被管理来缓解。在这项研究中，我们将表征与草地生物多样性恢复相关的关键草地植物物种的不同特征，并测试其对草地生态系统服务的影响，包括温室气体二氧化碳，甲烷和氧化二氮，土壤微生物活性以及养分循环和养分。这将提供有关植物多样性用于操纵土壤养分循环的可能性的第一份信息，以朝着更大的碳和氮气存储，以及较低的温室气体排放。
