Dynamic Analysis on Landscape Map of Qinhuangdao City

Dynamic analysis on landscape map is to study ecological structure of landscape by using the information of landscape type map as basic data. In this paper, Qinhuangdao City is the study area, Arc / Info, Fragstats and some other software are the technical support. Based on the establishment of landscape type map, this paper extracts landscape indices like density size and size difference index, edge index, diversity index, concentration and scattering index, etc. It also analyzes land cover landscape structure and evolution processes of different landscapes in different periods of time, in order to reveal the variation rule of their spatial patterns.
