中文摘要：

通过对世界3大顶尖刊物《Science》、《Nature》及《Proceeding of National Academy of Science》（PANS）近5年的土地变化及其有关重要论文检索与归纳,并在参阅了其他有关重要期刊后,简要回顾了由土地利用或覆盖变化（LUCC）研究到土地变化科学（land change science,LCS）的产生过程,特别提出了因全球变化研究而发现土地变化重要性是LCS产生的科学原因.随后,提出了当前土地变化科学的重要研究领域——可持续性影响评估（sustainability impact assessment,SIA）,并指出跨学科、创新地认识土地利用的生态、社会、经济等多功能（MLUs）,且以土地利用多功能（LUFs）概念为框架,定量构建综合SIA评价指标体系的核心研究趋势.

英文摘要：

Through checking and concluding the articles of last five years from the top three journals in the world： Science, Nature and Proceeding of National Academy of science （PNAS） and referring to the relative journals, this article simply reviews the key process of LUCC transforming to Land change science（LCS）, especially, the finding of land changes significance is the main scientific reason of land change science emerging from global change research. Then, the current important research field of sustainability impact assessment （SIA） in LCS is advanced out. The inter-disciplinary, innovative viewpoint of multifunctional land uses（MLUs）are recognized as the main base of SIA. The core research trend of the assessment indictor quantitative model is implied based on the framework of land uses multifunctions （LUFs） concepts of ecological, social and economical functions.
