松原市土地利用景观格局时空演变特征
Temporal and Spatial Evolution Characteristics of Land Use Landscape Pattern in Songyuan City
摘要
Abstract
Taking Songyuan City of Jilin Province as the research area,the spatial-temporal changes of landscape pattern in Songyuan City from 2000 to 2020 was analyzed by GIS spatial analysis and other methods.The results showed that the landscape type of Songyuan City was mainly dominated by cultivated land,the areas with significant changes were cultivated land,construction land and unused land.In the past 21 years,the total area of cultivated land had consistently accounted for over 75%of the total area.The area of construction land had increased o-verall,the area of unused land had sharply decreased.The area of forest and grassland had shown an overall increasing trend,the area of culti-vated land and water had shown an overall decreasing trend.From 2000 to 2010,the fragmentation of the landscape in Songyuan City showed an increasing trend,with frequent transitions between landscape types.The degree of regional landscape fragmentation and the complexity of landscape shapes continued to increase,with weak landscape connectivity,particularly in the southern part of Songyuan City.From 2010 to 2020,there was relatively little transformation between landscape types,and urban landscapes continued to develop towards fragmentation and irregularity,but the degree of change was much smaller than from 2000 to 2010.关键词
