Regulation and Mechanisms of Carbon Effects by Land Use Change

Abstract

Land use change is one of the most direct and significant impacts of human activities on the Earth system. It not only changes the physical characteristics of the land surface, but also affects the energy, water, and material cycles of the Earth, and thus affects the global and regional climate change and ecosystem services. Among them, the impact of land use change on the carbon cycle is particularly important, because the carbon cycle is one of the most basic and critical cycles in the Earth system. It determines the greenhouse effect and climate sensitivity of the Earth, and also affects the biodiversity and productivity. This paper systematically analyzes the impact and mechanism of the carbon effects of land use change on different ecosystem types, different geographic regions, different climate conditions, different land use modes and management measures from different angles and levels, using various methods and models, evaluates the factors such as the size, direction, persistence, and sustainability of the carbon effects of land use change, proposes some evaluation and promotion of management techniques and measures, as well as policy suggestions and institutional designs for the carbon effects, and provides scientific basis and reference suggestions for the optimization and control of the carbon effects of land use change.
