土地资源优化配置已成为土地科学领域前沿的重要课题，而近年来受到国内外学术界重视的土地利用/土地覆被变化研究正可为此提供支持，并相互促进。如何正确认识二者之间的关系，并有效的利用这种关系，无论对我们研究土地利用/土地覆被变化，还是实现土地资源优化利用都异常重要。本文对二者的研究目标及内容进行对比分析，并在此基础上详细阐述了二者的结合方式和途径，提出土地利用/土地覆被变化能为土地资源优化配置提供数据、理论、研究方法支持，同时土地资源优化配置研究有益于土地利用/土地覆被研究的深化，二者的结合可促进土地可持续利用。

Land is the most important physical basis for the existence and development of the human being. With the growth of population and the rapid development of industrialization and urbanization, the shortage of land resources is becoming more and more serious. It has been felt that land must be used rationally. Now the optimal allocation of land resources is becoming a significant study task, and the land use and land cover change study plan, which is attached importance recently by academe, can offer support and accelerate each other. Therefore, how to understand their relationship and make use of the relationship effectively becomes the key problem. It not only can help the study of land use and land cover change but also is important to the optimal allocation of land resources. In this paper, the main aim and content of LUCC are firstly introduced and analyzed. Based on the analysis, the way of connecting land use and land cover change with regional optimal allocation of land resources is discussed systematically. It presents that land use and land cover change study can offer data, theory and technology support to the study of land resource optimal allocation, and at the same time, the study of land resource optimal allocation can make the study of land use and land cover change deeply and profoundly. The connection of them can promote the sustainable land use.
