ZY-3 satellite image based analysis of overall landscape patterns in Huai’an-Yangzhou section along the Grand Canal

Abstract

This paper studies the overall landscape patterns in Huai’an-Yangzhou section along the Grand Canal with RS (Remote Sensing) and GIS (Geographic Information System) based on ZY-3 satellite images of this area. During the study, the landscapes of Huai’an-Yangzhou section along the Grand Canal have been classified into six types, i.e. farmland landscape, garden and forest landscape, water landscape, architectural landscape, road landscape, and other landscapes. Meanwhile PD (Patch Density), perimeter area fractal dimension (PAFRAC), and AI (agglomeration index) of different landscapes in these two heritage sites have been calculated, whose results show that farmland landscape, architectural landscape, and water landscape are the three most obvious landscapes with a high degree of concentration in the two heritage areas. The findings can provide basic data for landscape protection and management of Huai’an-Yangzhou section along the Grand Canal.
