| 中文摘要: |
| 由于城市发展的速度加快,酸雨的频率和强度逐渐增加,对土壤生态系统的危害日益严重。本文从酸雨对土壤有机碳含量的影响和土壤有机碳转化机理的基础上,总结了酸雨对土壤生态系统影响的相关研究成果,包括以下几个方面:1)酸雨对土壤养分矿化的影响;2)酸雨对土壤团聚结构的作用;3)酸雨对土壤碳(C)、氮(N)、磷(P)等养分元素的平衡关系。由于研究区域的气候、土壤类型及耕作方式等因素不同,酸雨对土壤碳固持的影响存在巨大差异,今后应加强从以下几个方面进行扩展实验:1)多种因素耦合关系研究;2)不同的酸雨类型组合研究;3)现场长期定位监控。 |
| 英文摘要: |
| The frequency and intensity of acid rain have gradually increased with the acceleration of urbanization and industrialization, seriously threatening soil ecosystems. In the study, the impact of acid rain on soil organic carbon content and mechanism of soil organic carbon conversion as an entry point related to soil ecosystems are summarized, including the following aspects:1)The impact of acid rain on soil nutrient mineralization, 2)the role of acid rain on soil aggregate structures and 3) the function of acid rain on the balance of soil nutrient elements, including carbon (C),nitrogen (N), and phosphorus (P). Due to the study area’s varying climates, soil type, and tillage methods, the effects of acid rain on soil carbon sequestration differ significantly. Future experiments should focus on the following aspects:1) research on the coupling relationship of multiple factors;2)research on the combination of different acid rain types, and 3) long-term site positioning monitoring. |
