The coastal counties of Zhejiang Province, China, are important for economic development, marine economy, and nature conservation. This study aimed to support sustainable land-use policies through the planning and management of 35 counties, using official land-use data from 1990 to 2020. Spatial analysis methods included transition matrix, land-use intensity, landscape-pattern indices, centroid shift, and standard deviation ellipses. Results showed a "north-cropland, south-woodland" structure, together over 75% of the area. Construction land expanded steadily to 20%, mainly from cropland, woodland, and grassland (87% of outflows). Inflows mainly involved construction land, woodland, and cropland (91%). The wetland was dominated by the river channel and mudflat. Mudflat and beach made up 94% of outflows; reservoir and pond, 78% of inflows. Land-use intensity increased overall, with Pinghu highest. Grassland centroid shifted 38.74 km. Ellipses showed directional changes. Land-use diversity and spatial complexity increased, reflecting intensified human influence and offering a basis for sustainable planning and ecological restoration.
中国浙江省沿海各县对经济发展、海洋经济和自然保护具有重要意义。本研究旨在利用1990年至2020年的官方土地利用数据，通过对35个县的规划和管理来支持可持续土地利用政策。空间分析方法包括转移矩阵、土地利用强度、景观格局指数、质心转移和标准差椭圆。结果显示，超过75%的区域呈现出“北部耕地、南部林地”的结构。建设用地稳步扩展至20%，主要来自耕地、林地和草地（流出量的87%）。流入的主要是建设用地、林地和耕地（91%）。湿地以河道和泥滩为主。泥滩和海滩占流出量的94%；水库和池塘占流入量的78%。土地利用强度总体增加，平湖最高。草地质心移动了38.74公里。椭圆显示出方向变化。土地利用多样性和空间复杂性增加，反映出人类影响加剧，为可持续规划和生态恢复提供了依据。
