摘要
基于RS与GIS技术,对银川市2006年、2011年、2016年遥感图像进行监督分类,并从景观类型面积、景观破碎度、景观优势度、景观多样性4个方面进行分析.结果表明:研究区建设用地面积迅速增加,耕地面积减少,草地、水域面积变化不明显,林地面积逐渐增加,荒地面积大幅度减少;研究区景观破碎度、景观多样性有所上升,景观优势度有所下降.水资源及利用方面,银川市2009—2016年水资源总量整体保持平稳,但水资源利用方式发生较大转变,其中农业用耗水量连年下降,城镇生活用耗水量急剧上升,分别与景观类型中的耕地与建设用地的面积变化成正相关.
Supervised classification of the remote sensing images of Yinchuan in 2006,2011 and 2016 were carried out by using RS(Remote Sensing)and GIS(Geographical Information Systems)technologies.Then the images were analyzed from four aspects,namely landscape type area,landscape fragmentation degree,landscape dominance and landscape diversity.It showed that in the study area,land for construction increased rapidly,cultivated land reduced grassland and water area didn′t change obviously,forest land gradually increased,and the wasteland greatly reduced.We also found that landscape fragmentation and landscape diversity increased,and the landscape dominance decreased.From 2009 to 2016,the total amount of water resources in Yinchuan remained stable,but the utilization mode of water resources changed greatly.Agricultural water consumption has been declining.Urban life water consumption has risen sharply,which was positively correlated with the change of the area of cultivated land and land for construction.
