莆田市土地利用格局的地形梯度特征变化及尺度效应
Characteristic change and scaling effect of the land use pattern in Putian city based on the terrain gradient
摘要
Abstract
Based on a digital elevation model (DEM) and three remote sensing images of Putian city in 1995,2005 and 2015,and with the help of the Remote Sensing and Geographic Information System technology,the characteristic of temporal and spatial changes of the land use pattern and scaling effect were systematically analyzed using terrain niche index,distribution index and landscape pattern index.Results showed that:(1) Forestland is mainly distributed in the high terrain sections,while construction land and water area,agricultural land and bare land are mainly distributed in the low terrain sections,and the low and middle terrain sections,respectively.(2) From 1995 to 2015,the main distribution area of construction land and agricultural land had been gradually expanded to the high terrain area,and the dominant distribution ranges of forestland and water area had not changed.(3) The landscape indexes that did not show scaling effect in any terrain sections were Shannon's diversity index,Shannon's evenness index and contagion index,while the landscape indexes that decreased with an increase of scale were patch density,landscape shape index and area-weighted mean fractal dimension index.关键词
