摘要
基于移动窗口法,对2014年苗二河流域森林景观格局进行分析。结果表明:非林地和有林地为优势地类景观,面积大,斑块形状较复杂,分布广泛;无立木林地为劣势地类景观,面积小,斑块形状较规则,分布比较集中;森林景观适宜景观粒度为150 m;森林景观适宜窗口尺度为900 m。基于粒度效应、面积信息损失精度和移动窗口法对苗二河流域森林景观格局的研究,可为优化流域森林景观提供参考。
Based on moving window, studying of forest landscape pattern analysis of Miaoer River basin in 2014 year. Results show that：non-woodland and woodland landscape patch shape complex, large size, widely distributed, as the advantaged class landscape; free standing woodlands for the disadvantaged class landscape, small size, patch shape regular distribution more concentrated;suitable for landscape size is 150 m ;suitable window scale is 900 m. Based on size effect, area information loss of precision and moving window, studying on forest landscape pattern of Miaoer River basin, provide scientific and reasonable reference for watershed forest landscape optimization.
