摘要
为了探讨生态移民安置区土地利用的景观格局特征,以及研究区不同土地利用的变化,以宁夏回族自治区红寺堡区为研究区,选取1995年、2005年和2015年三期遥感影像数据,运用RS和GIS技术分析了该区域的土地利用的景观格局变化特征,定量分析了几种常用景观格局指数随尺度的变化规律。结果表明:红寺堡区土地景观要素占绝对主导地位的是草地,其次为耕地;各类土地景观变化较为复杂,总体而言,红寺堡区土地景观正朝着破碎度、异质性程度增加的趋势发展。
In order to study the landscape pattern and the change of land use in the study area,this paper took Ningxia Hui Autonomous Region Hongsibu district as the study area,selected the remote sensing image data in1995,2005and2015,analyzed the regional land use landscape pattern using RS and GIS technology,quantitative analysis of several commonly used index of landscape pattern changes with scale.The results showed that:The dominant landscape elements in Hongsibu was grassland.As the limitation of water area,the conversion activities with other land landscape types were the weakest.All types of land landscape pattern fluctuated complex.But overall,the land landscape was developing towards the trend of fragmentation and heterogeneity.
