摘要
以2010年和2014年两期遥感影像为数据源,综合利用RS技术、GIS技术和景观生态学方法,对北戴河区2010~2014年的土地利用景观格局变化进行了分析。结果表明,北戴河区景观类型以建设用地、林地为主;2010~2014年建设用地面积增加,耕地、林地、草地、未利用地面积减少;2010~2014年北戴河区景观斑块数量和密度增加,平均斑块面积减小,景观破碎化程度有所增加,景观Shannon多样性指数和均匀度指数下降,异质性程度有所降低。
Based on the two remote sensing images in 2010 and 2014,the changes of land use and landscape pattern of Beidaihe District from 2010 to 2014 were studied by remote sensing,GIS technology and the landscape ecological theory in this paper.The results show that the main landscape types are construction land,forest land and cultivated land.From 2010 to 2014,the area of construction land increased,while the area of cultivated land,forest land,grassland,water,unutilized land decreased.At the level of landscape,the number of patches(NP) and the density of patches(PD) increased,while the mean patch area(MPS) decreased,which indicating that the degree of landscape fragmentation increased.The Shannon's diversity index(SHDI) and Shannon's evenness index(SHEI) decreased,which indicating that the degree of landscape heterogeneity decreased.
