摘　　要：本文回顾了国内土地利用调查和土地利用/覆被变化(以下简称LUCC)的研究历程,认为20世纪80年代前的半个世纪,我国以土地调查为主的土地利用研究发展缓慢。到了80年代后,由于遥感技术由实验走向实用、地理信息系统技术的普及,加之IGBP和HDP两大组织发起的土地利用/覆被变化研究,这一领域的研究得到了极大地推动。目前,该领域存在着技术潮流、驱动力研究潮流、环境效应研究潮流、景观生态学潮流等热点,这对于推动LUCC的多学科深入研究具有积极作用;指出了土地利用/覆被变化研究中存在的"重技术轻学理"现象、微观机理研究不足、忽视土地利用替代性研究、土地可持续利用评价针对性不够、研究的服务对象单一等问题,LUCC研究要在克服这些问题中发展;由此提出,在经过一定的领域拓展、案例积累、技术准备等基础工作之后,我国土地利用/覆被变化研究应针对前述问题,加强理论建设,探索模型建立,拓展区域应用,发挥多学科核心作用,在理论建设、数学模型表达、机理探讨等方面,为现代地理学做出贡献,为地理学的社会作用和应用拓展更加广阔的空间。This paper reviews the study process of the land use and land cover change and thinks that the development of the study on land use, which took land use survey as the dominant way in the early 1980s, was slow. Until the late 1980s, the study on land use developed quickly because of the development of remote sensing from experiment to actual use as well as the advantages of the geographical information system. The research of land use initiated by the International Geosphere-Biosphere Programme （IGBP） and the Human Dimensions of Global Environmental Change Programme（HDP） also promoted the development of the study. At present, the Study hotpots such as technology applying trend and driving force study trend, landscape ecological research trend promote the study of many subjects in land use and land cover change. This paper also points out the problems in the land use and land cover change, such as giving emphasis on technology but neglecting theory, insufficient in microcosmic mechanism and target of the sustainable land use evaluation, ignoring substitutional study of land use, and unitary study of the service of the object. The study of land use and land cover change is conducted based on these problems mentioned above. After frontier extension, case accumulation, and technology preparation, the study on land use and land cover change should aim at these problems to strengthen the theory, grope for model and mechanism construction, extend the using frontiers, and bring the multi-subject into play. The land use and land cover change contributes to modem geography, brings geography into play, and extends a wide frontier for application in theoretical construction, math model expression, mechanism probing and so on.
