摘要
土地利用/覆盖变化(LUCC)是人类活动行为与自然生态系统相互作用最为直接的表现形式.近年来由于人类活动的日益加剧使区域生态环境发生了剧烈变化,中国北方农牧交错带作为人类活动的强烈影响区和生态环境敏感区,是土地利用/覆盖变化研究的"热点区域".本综述基于众多学者对于北方农牧交错带LUCC的研究成果,梳理了关于北方农牧交错带范围界定的进展,总结了当前有关本地区LUCC的研究手段、研究内容以及环境效应与应对措施等方面的最新进展,最后指出了本地区LUCC研究中存在的综合性模拟研究较少、生态环境效应不足等问题,并提出了未来研究中应多手段、多学科、多尺度研究的发展方向.
Land use/cover change（ LUCC） is the most direct manifestation of the interaction between human activities and natural ecosystems. In recent years,due to the increasing human activities,regional environment has been dramatically changed. As one of heavily influenced and fragile and vulnerable ecosystems,the agro-pastoral ecotone in Northern China is a ＂hot spot＂for land use/cover change research. Based on a literature review of LUCC in the agro-pastoral ecotone in Northern China,we first systematically summarized the progress of the boundary definitions of the agro-pastoral ecotone,and then synthesized the current findings,methods,procedures,topics,environmental impacts and adaption of LUCC in the region. Finally,we proposed that few comprehensive,process-based ecosystem simulations and eco-environmental impact studies had been reported in the current LUCC research and called for more multi-disciplinary,multi-methods,and multiscale researches in the future LULC research in this area.
