基于Landsat遥感数据的长岛南部岛群景观格局演化研究
Study on the evolution of landscape patterns in the south of the Changdao Island based on Landsat remote sensing data
摘要
Abstract
This paper aims to classify the landscapes of the southern islands of the Changdao Island chain using the Landsat TM5, TM7, and OLI8 image data sources from 1990 to 2015, based on the Geographic Information System (GIS) platform and the decision tree classification method. The Frag-stats software was used to extract the pattern indices of the seven different landscapes. The landscape pattern evolution characteristics of the southern island group of the Changdao Island chain were systematically analyzed. The results showed that the anthropogenic activ-ity was the main driving force for the evolution of the landscape pattern for this landscape in recent years. The landscape pattern was characterized by the increase of construction, aquaculture, and forest land, the increase of the aggregation index of plaques every year, and good aggregation degree and connectivity of plaques. Different land-scape indices, i.e., Patch Density (PD), Aggregation Index (AI), Class Area (CA), Landscape Shape Index (LSI), Patch Cohesion Index (COHESION), Shannon's Diversity Index (SHDI), all exhibit characteristics of human dis-turbance factors. The conclusion can provide the effective basis for the integrated management of the island groups and the delineation of ecological red lines.关键词
