摘要
在3S技术的支持下,利用MSS及TM遥感影像数据,结合实地调查数据,提取太白山自然保护区1979、1988、2000、2006年景观格局信息,并利用景观多样性、景观优势度、景观破碎度等指数,分析了太白山自然保护区近30年来的景观结构变化。结果表明:从景观类型上看,太白山自然保护区各景观类型的变化趋势和幅度存在明显差异;从不同类型的景观格局指数上看,各景观类型在不同的年份受到的干扰不同;景观格局具有明显的时空分异特征,在空间上表现为景观多样性和破碎度的梯度变化特征明显,在时间上表现为景观多样性和破碎度的变化。
Based on four remote sensing images （MSS in 1979, TM in 1988, ETM in 2000 and TM in 2006 of Taibai Mountains Nature Reserve）, the interpretation symbols in combination with the field survey are set up, and the landscape structure changes for 30 years in this area is analyzed by computing the landscape index. The results show that from the point of view of landscape types, the change trend and amplitude of landscape type exists obvious difference; as can be seen from the different types of landscape pattern index, different types have different interference in different years： Research also proved that the landscape pattern has obvious differentiation characteristics of space and time, on the space of landscape diversity and fragmentation of gradient variation characteristics significantly, in time for the change of landscape diversity and fragmentation.
