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.
