Abstract
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.
期刊介绍:
Science has many big remaining questions. To address them, we will need to work collaboratively and across disciplines. The goal of iScience is to help fuel that type of interdisciplinary thinking. iScience is a new open-access journal from Cell Press that provides a platform for original research in the life, physical, and earth sciences. The primary criterion for publication in iScience is a significant contribution to a relevant field combined with robust results and underlying methodology. The advances appearing in iScience include both fundamental and applied investigations across this interdisciplinary range of topic areas. To support transparency in scientific investigation, we are happy to consider replication studies and papers that describe negative results.
We know you want your work to be published quickly and to be widely visible within your community and beyond. With the strong international reputation of Cell Press behind it, publication in iScience will help your work garner the attention and recognition it merits. Like all Cell Press journals, iScience prioritizes rapid publication. Our editorial team pays special attention to high-quality author service and to efficient, clear-cut decisions based on the information available within the manuscript. iScience taps into the expertise across Cell Press journals and selected partners to inform our editorial decisions and help publish your science in a timely and seamless way.
