基于Fragstats的邯郸市城区绿地景观格局研究
|
摘要
以2014年遥感影像Landsat8为基础,利用ENVI遥感图像处理软件对影像数据进行波段组合、融合、裁剪、增强等预处理,采用面向对象的方法对邯郸市三区的绿地信息进行提取。对提取结果进行绿地分类,利用Fragstats景观处理软件,选取景观斑块密度指数、景观斑块破碎度指数分析,进行景观格局定量评价,以此探讨绿地系统景观格局存在的问题,并为绿地景观格局的优化提供依据。从而在提高城市绿化率的基础上,优化绿地景观格局,构建科学合理的城市绿地系统,充分发挥城市绿地在城市建设发展中的生态作用,提高人民生活水平。
This paper adopted the object-oriented method to extract the green space information of three districts of Handan City areas on the basis of Landsat8 remote sensing images in 2014 and using ENVI remote sensing image processing software for pretreatment such as band combination,image data fusion,cutting and enhancement. The extraction results were classified for green spaces,and then the Fragstats landscape processing software was used for quantitative evaluation of landscape pattern with the analysis of selected landscape plaque density index and landscape fragmentation index,in order to discuss the problems arising in systematic landscape patter of green spaces. This study is to optimize green space landscape pattern,construct the science-based and reasonable urban green space system,give full play to the ecological role of urban green space in urban development,and improve people's living standards on the basis of improving the city green area.
