以土地利用/土地覆被变化为中心的土地科学研究进展

土地利用 /土地覆被变化已成为土地科学、地球系统科学、全球环境变化及可持续发展研究中的核心领域。其研究的根本目标是实现土地资源的有效管理与可持续利用 ,这不仅是解决资源与环境问题的根本立足点 ,也是经济增长与区域可持续发展过程的重要前提。针对国际土地科学研究中最为活跃的几个前沿领域 :土地利用 /土地覆被变化、土地资源系统分析与评价、土地质量指标体系、生态环境效应及持续土地利用 ,结合近年来国内外有关的主要研究计划和项目 ,本文对以土地利用 /土地覆被变化为中心的土地科学研究进展进行了综述。

The Progress on Comprehensive Land Sciences focused on Land-use and Land-cover change

Land use and land cover change has become the core region of land sciences, earth systematic sciences, global environmental change and sustainable development. The fundamental objective of such research is to realize the effective management and sustainable use of land resource. They are not only the fundamental basis to solve the problem of resource and environment, but also the essential predomination for the economic growth and the process of regional sustainable development. Taking major related research plans and projects both in China and abroad in recent years for reference, this paper summarized the up to date international progress of several regions in the land science, such as land use and land cover change, systematic analysis and evaluation of land resources, land quality indicators system, impacts on ecological environment and the sustainable land use.
