摘要
基于2006年4月～2011年4月的多级、多源、多时相遥感影像,利用摄影测量、图像处理、影像解译、信息分类等相关技术,对西安世界园艺博览会园区不同时期的土地利用、地理变化、园区建设进度变化进行监测解译和对比分析。研究结果表明:西安世界园艺博览会侧重植被与湖泊的建设,地理环境优化得到明显的改善。截至2009年4月,世园会的主体结构已布局好;2011年3月,园区内的道路、附属设施、湖泊、建筑物等已基本建成;2011年3月～4月,主要为展示植物等移入时间。
Based on multi-level, multi-source, multi-temporal remote sensing images from April 2006 to April 2011, the land use, geographieal changes and construction progress of Xi＇an International Horticuhural Exposition Park are monitored and analyzed. In the process of research, photogrammetry, image processing, image interpretation, information classification and other related technologies are adopted. The experiment results show that： Xi＇an International Horticultural Exposition focuses on lhe construction of vegetation and lakes; the geographical environment has been improved significantly. Up to April 2009, main structure of Xi＇an International Horticultural Exposition Park has been planned well; and up to March 2011, roads, ancillary facilities, lakes and buildings in the park have been basically completed; displaying plants are moved in mainly from Mareh 2011 to April 2011.
