摘要: 以西安汉长安城遗址作为实证研究地区,利用2018年和2020年的Landsat TM影像数据为数据源,基于地理信息系统(Geographic Information System,GIS)及遥感影像(Remote Sensing,RS)技术进行景观格局分析,以期为大遗址区的保护与利用提供科学数据。将遗址区内现有土地使用状况归纳成六大类,利用景观指数分析方法,对西安市汉长安城遗址区内的景观格局进行规划和研究。从规划实践的角度配合因子分析选择指数,筛选出11个景观指数进行实证研究与方案评估,研究结果显示,该区道路与水体嵌块体的形状最复杂;草地嵌块体的分布最离散,并与其他类型嵌块体的相接程度最高;道路与林地嵌块体的连接度高,具有作为生态廊道的优势。

Abstract: Taking Han Chang'an City relic as an empirical area, based on the Landsat TM remote sensing data collected in 2018 and 2020, and combining RS and GIS technique, to analysis the landscape pattern, aiming to provide more scientific statistic for the planning of a historical site. The study divided the relic area into six parts. Landscape pattern analysis method is used to plan and study the landscape of the Han Chang'an City relic in Xi'an following the data of GIS(Geographic Information System) and RS(Remote Sensing). The index is selected from the perspective of planning practice with factor analysis, and 11 landscape indexes are selected for empirical research and program evaluation. The results shows that the shape of road and water blocks is the most complex; the distribution of grassland embedded blocks is the most scattered, and the connection with other types of embedded blocks is the closest. The closer connection between the road and woodland blocks makes the site a perfect ecological corridor.

Key words: remote sensing data, Han Chang'an City relic, landscape pattern
