中文摘要	地理结论的可靠性一直以来是地理学家关注的焦点问题。本研究建立了基于高分辨率遥感信息获取的土地利用/覆盖变化数据和参考文献集成与再分析方法。以陕西省为例,通过土地利用/覆盖变化动态数据分析结果与研究区40篇参考文献分析结果进行相互验证,提炼土地利用/覆盖变化以及驱动机制的知识规律。结论表明,基于土地利用/覆盖变化数据的分析结果与参考文献集成分析的结果基本一致。1990年-2005年陕西省耕地总面积减少,耕地呈先增加后减少的趋势;林地和草地面积逐渐增加;建设用地快速增长。人口、经济、政策与城市化是该省土地利用/覆盖变化主要驱动因子。2000年以来实施生态退耕工程对土地利用/覆盖变化的影响程度较大。
英文摘要	Geographical conclusion reliability has been an important topic for geographers. This study proposed a new technique to integrate data on land use/land cover change, remotely sensed information, as well as the scientific literature. First, the project team constructed the global land information platform (GLIP), including the global land use/land cover the electrical scientific literature base and multi-scale LUCC data. Global Land Use Scientific Literature Base (GLUSLB) has more than 5000 references on land use and land cover. We reclassified the scientific literature into 6 classes, including application, technology, methodology, review, model, and data. Furthermore, the scientific literature on application and data with definite location is located in the specific geo-ecological region. Second, compared with land use and land cover change areas from between LUCC data and 40 references, spatial and temporal characteristics and their driving mechanisms were analyzed. Results indicate that the conclusions are generally consistent with both of them, especially the land use change characteristics from different administrative systems. From 1990 to 2005, the total area of cultivated land in Shaanxi Province generally decreased, but increased during the period 1990-2000 and then decreased during the period 2000-2005. The forest and grassland area decreased. On the contrary, the constructed land increased. Yulin, Xi’ an Prefecture, and the loess plateau region have become the hot areas. Cultivated land decreased but forest and grassland increased, especially since 2000, as a result of the implementation of the ecological project in Yulin Prefecture. It was found that at the same time, the sand area decreased due to land desertification prevailing in this area. Urban-rural construction land rapidly increased due to urbanization and economic development in Xi’ an Prefecture. Land use transformation has changed greatly during the period 1990-2000 compared with the period of 2000-2005 in the loess plateau region. Forest and grassland increased firstly and then decreased in this region. It was also found that human activities were a more dominant factor than natural factors. Population growth, economic development and urbanization are the main driving factors on land use change. The "Grain for Green" policy implemented since 2000 has brought a great impact on land use change in Shaanxi Province.
