摘要/Abstract

摘要： 在景观生态学中,景观动态和影响因子一直是研究的热点问题。运用4期遥感影像(陆地卫星TM/ETM)的监督分类结果为基础数据源,提取了研究区内土地利用类型和景观两个级别的景观指数,运用向量理论、中性景观模型建立一个多维的坐标体系,并采用EUD和CAD对景观动态进行分析。结果表明人类活动对景观的演替产生一定的影响,改善人为景观或使景观分布更随机;在景观演替过程中,不同层次景观的演替速度和方向的变化存在差异性,只有城镇变化过程与区域景观过程保持同向变化。

关键词: 3S, 矢量理论, EUD, CAD, 中性景观模型, 景观动态

Abstract: Landscape dynamics and driving factors are always hot issues in landscape ecology.To demonstrate the landscape dynamics and the effects of anthropogenic activities,we performed supervised classification on 4 remote sensing images(Landsat TM/ETM)to extract two hierarchical landscape characteristics according to the class indices and landscape metrics vector.A multi-dimension coordinating system was constructed using the neutral landscape model based on the vector theory to analyze the changes of class and landscape characteristics via EUD and CAD.We found that the anthropogenic activities may affect the landscape succession by improving anthropogenic landscape or further randomizing the landscape distribution.In the process of landscape succession,the rate and direction of change were inconsistent for different hierarchical landscapes and only the urban change process remained consistent with the general landscape.

Key words: 3S, vector theory, EUD, CAD, neutral landscape model, landscape dynamics
