摘要
首先基于大兴安岭2005—2020年的遥感影像,结合土地利用数据,利用GIS技术进行景观类型面积分析,使用土地利用转移矩阵探究土地利用结构变化.其次利用景观格局计算软件对该地区景观指数进行分析,得出景观格局变化特征,最后在此数据基础上,基于压力-状态-响应(pressure-state-response-PSR)模型,得出该区域2005—2020年生态系统健康结果,能够为政府资源与环境部门未来规划提供可靠的数据支持和决策依据.
Abstract
This article is firstly based on remote sensing images of Daxing'anling prefecture from 2005 to 2020,combined with land use data,using GIS technology for landscape type area analysis,and using land use transfer matrix to explore changes in land use structure. Secondly,the landscape pattern calculation software was used to analyze the landscape indexes of the region and obtain the characteristics of landscape pattern changes. Finally,based on this data,the pressure state response (PSR) model was used to obtain the ecosystem health results of the region from 2005 to 2020,which can provide reliable data support and decision-making basis for future planning of governmental resources and environment departments.
