中文摘要: 典型地区历史时期土地利用/覆盖变化一直是国际关注的问题之一,重建历史时期区域尺度上的土地利用变化的综合研究既是参与全球环境变化研究的具体途径,也为全球变化提供丰富的区域信息。本研究将基于中、藏文历史档案和文献及近60年来的相关统计、地图、遥感卫星等数据,重建历史时期青藏高原典型区域重大历史事件、自然事件相对应的土地利用变化格局,对比分析青藏高原不同典型区域历史时期土地利用变化的特征,并利用区域气候变化、自然灾害、政策管理、器测数据等高分辨率信息,从人类-环境耦合系统的角度探讨青藏高原典型区历史时期土地利用格局对区域气候变化、自然灾害、政策管理等外界因素的响应机制,为该地区土地利用政策和可持续发展提供必要的理论和经验启示。

英文摘要: Historical land use and land cover change of representative regions have attracted much scientific attention. The comprehensive researches of reconstructing historical land use change on regional scale not only access to the global environment change researches, but also provide rich regional information for global change studies. Based on Chinese and Tibetan historical archives and documents, statistics, maps, and remote sensing satellite data in recent 60 years, etc, this study reconstructs historical land use pattern change of the representative regions in the Tibet Plateau and important social and natural events related to land use change in history. The land use change characteristics of different representative regions in the Tibet Plateau were analyzed. On the perspective of human-environment coupled system, we discuss the response mechanism of historical land use pattern to regional climate change, natural disasters, policy management, and other external factors by using regional climate change, natural disasters, policy management, metrological and such high resolution information. This provides necessary theoretical and experiential suggestion for regional land use policies and sustainable development.
