中文摘要以地学信息图谱的理论为指导,经过图形思维与抽象概括,从景观生态专题制图入手,实现干旱区景观生态信息图谱的数字表达。以20世纪90年代初、2000年的TM和2005年的CBERS-2/CCD影像作为提取景观信息图谱的基础资料,配以1:25万的DEM数据,以及吐鲁番地区的地形图和文字资料;选择吐鲁番绿洲、鄯善绿洲、天山及戈壁区、艾丁湖区五个区域为主要研究区,依据干旱区山地-绿洲-荒漠耦合系统以及本研究区所特有的自然景观特征,对选定研究区进行景观类型划分,划分为景观一级分类和景观二级分类,共有4个大类13个亚类,完成了景观要素的分类定级;以景观生态专题制图设计为向导,借助GIS符号库,并结合研究区景观自然面貌特征,从美观实用的角度,设计了景观生态专题制图符号体系,实现了景观要素的图谱表达;在ERDAS IMAGINE 8.5、ArcGIS9.0的支持下,完成专题图的制作;依靠Microsoft Office Access 2003平台,设计并建立景观生态信息图谱数据库,最终确定景观生态信息图谱模式。在整个研究过程中贯穿了地学信息图谱、地理信息系统和景观生态学的理论与方法,最后总结得出景观生态信息图谱模式:由图形和特殊符号、描述性数字参数、数学模型3个成分组成。为景观生态信息图谱的进一步研究提供借鉴,为当地生态环境建设决策提供有力的科学依据。Based on the Geo-Info TUPU System theory and ecological landscape mapping, this study actualizes digital expression of arid area ecological landscape information TUPU. It takes the TM (in the beginning of the 1990 and 2000 years), the CBERS-2/CCD (in 2005) and the DEM as the basic data to extract ecological landscape information TUPU System. According to the MODIS coupled system of the arid area as well as the local natural characteristic. This study chooses the oasis of Turpan, the oasis of Shanshan, the area of Tianshan, Gobi and the area of Aydingkol Lake as the main research areas. And it divides these research areas into two level classification, 4 kinds and 13 subgroups. Besides it designs the landscape ecology thematic symbols practicably with the support of ecological landscape mapping, the GIS marks and the local natural characteristic to complete the expression of ecological landscape TUPU. The thematic map is completed with the support of ERDAS IMAGINE8.5 and ArcGIS9.0. Using Microsoft Office Access 2003 to design and carry on the database of ecological landscape information TUPU System. Finally, this study obtains the mode completely. Throughout the entire research process, this study includes the theory of Geo-Info TUPU System, Geographic Information System and the landscape ecology. It obtains the mode of landscape ecology information TUPU: Graph and distinctive mark, descriptive parameter and mathematical model. This is a reference for the further research of landscape ecology information TUPU, and provides the powerful scientific determination for the local decision-making of the ecological environment construction.
