Abstract

Based on Landsat ETM+ remote sensing data and historical geography analysis, this paper studied structural characteristics and driving factors for polder (artificial dike-surrounded field) landscapes in the East Chaohu Area of Anhui Province, China. According to the characteristics of polder structure and spectral analysis of typical objects, differential methods were used to gain structural characteristics of polder landscape in this area. The results indicated that the spatial structural characteristics of polder landscape could be divided into six categories: polygon-shaped structure, jaggies-shaped structure, dendritic-shaped structure, feather-shaped structure, cricoid fan-shaped structure, and rectangular-shaped structure. All six landscape structures were formed by the long-term human exploitation of farmland, reflecting different natural and social functions of polder's construction. Finally, combined with regional environment and historical literature, this paper synthetically analyzed the five main driving factors of this artificial field development.

基于Landsat ETM+数据的东巢湖圩田景观结构特征及驱动因素分析

基于Landsat ETM+遥感数据和历史地理分析，研究了安徽巢湖东部圩田景观的结构特征及其驱动因素。根据圩田的结构特点，结合典型地物的光谱分析，采用差分方法获取该地区圩田景观的结构特征。结果表明，圩田景观的空间结构特征可划分为6类:多边形结构、锯齿状结构、树突状结构、羽毛状结构、环状扇形结构和矩形结构。这六种景观结构都是人类对农田的长期开发而形成的，反映了圩田建设的不同自然功能和社会功能。最后，结合区域环境和历史文献，综合分析了该人工田发展的五大驱动因素。
