【摘要】 土地利用/覆盖的变化是影响陆地生态系统碳收支的主要因素之一,不同的土地利用/覆盖类型的碳循环机制存在很大的差异,每种土地利用/覆盖类型受人类活动干扰的程度和方式不同,因此表现出的碳收支状况也就不同。为了准确认识不同土地利用/覆盖类型的变化对陆地生态系统碳循环的影响,人们必须掌握不同土地利用/覆盖类型的碳循环特点。本文主要围绕几种典型的土地覆被类型的碳收支平衡特点进行分析,并对土地覆被变化对碳收支影响的最新成果进行综述,旨在表现不同的土地利用/覆盖类型碳收支特点以及研究方法的现状和趋势,为科学地利用土地、正视土地覆被的重要性提供理论依据。更多还原

【Abstract】 Land use/cover change is one of the main factors affecting the carbon budget of terrestrial ecosystems. The carbon cycle mechanisms of different land use/cover types are quite different. Each land use/cover type is affected by human activities in different degrees and in different ways, so the carbon balance is different. In order to accurately understand the impact of different land use/cover types on the carbon cycle of terrestrial ecosystems, one must master the carbon cycle characteristics of different land use/cover types. This paper focuses on the analysis of the balance characteristics of several typical land cover types, and summarizes the latest achievements in the impact of land cover changes on carbon budget. The aim is to express the characteristics of different land use/cover type carbon budgets and the status and trends of research methods, and provide a theoretical basis for the scientific use of land and the importance of land cover.更多还原
