土地利用变化对生态环境的影响

Impacts of land use changes on ecological environment

土地利用/覆盖变化是全球气候变化的一个重要方面,它不仅改变了地表结构,同时也改变了生态系统的服务功能,土地利用与生态环境的关系是生态学、地理学等学科交叉领域的前沿课题。在此基础上,本文拟从土地利用变化、生态系统内涵及影响梳理土地利用变化对生态系统服务的作用的影响,总结国内外研究成果,并在此基础上,为区域土地利用变化及生态环境效应研究提供理论依据。

Land use/cover change is an important aspect of global climate change,which not only changes the surface structure but also alters the service functions of ecosystems.The relationship between land use and ecological environment is a frontier topic in interdisciplinary fields such as ecology and geography.Based on this,this paper intends to clarify the impact of land use changes on the service functions of ecosystems from the perspectives of land use changes,ecosystem connotations,and impacts,summarize domestic and foreign research results,and provide theoretical basis for the study of regional land use changes and ecological environmental effects.
