Study on Land Use and Landscape Pattern Change in Qinzhou City from 2000 to 2020
Based on the land use data of 2000,2010,and 2020,the spatiotemporal variation law of land use and landscape pattern in Qinzhou city were explored by using GIS technology and supported by ArcGIS 10.8 and Fragstats4.2,the land use transition matrix and landscape pattern index were obtained,respectively,and the spatiotemporal evolution characteristics of land use and landscape pattern in the study area were analyzed.The results showed that:forest land was the most prominent land use in Qinzhou city,and it continued to increase every year.On the other hand,the area of cultivated land witnessed a continuous decrease,while the area of construction land kept on increasing.The changes in grassland and water area were observed to be fluctuating.From 2000 to 2020,the largest conversion of land was from forest and construction land to cultivated land.Net inflow was observed in construction,forest,and grassland,while cultivated land,water area,and unused land experienced net outflow.There were significant differences in the fragmentation of different landscape types,and the overall landscape fragmentation degree was deepened.The land use was abundant,and different landscapes tended to be complex,with their types evenly distributed.
