河北省海岸带土地利用空间格局

海岸带由于其特殊的地理区位，土地利用方式和结构迥异于内陆地区。为揭示河北省海岸带土地利用空间格局，以海岸线向陆地延伸10 km作为研究范围，通过土地利用相对优势度和综合利用程度两种方法分析了河北省海岸带土地利用结构现状、空间格局和集约化特征。结果表明:河北省海岸带土地利用的主要类型为水库/坑塘、旱地和建筑用地；水库/坑塘、河流/湖泊和建筑用地、未利用地向海特征显著，是海岸带的优势土地利用类型；海岸带土地利用的海陆梯度和高程分异特征明显，主要表现为主要土地利用类型由水库/坑塘和建筑用地向旱地和林地转变；集约化利用程度最高的区域在距海岸线0～6 km、高程10～50 m的空间范围内。在沿海开发热潮再次兴起的背景下，关注海岸带土地利用空间格局现状，对优化海岸带国土空间开发格局具有重要意义。

Spatial Patterns of Land Use in Coastal Zones of Hebei Province

As the special location,the use of coastal land is totally different from that of continental interior. Taking the terrestrial part of a 10 km buffer zone of coastline as the study area in this paper, we analyzed the structures, spatial patterns and intensive characters of land uses in coastal zones of Hebei Province. The results show that reservoir pool/reed pond, arid land and construction land are dominant types of land uses in costal zones of Hebei Province. Reservoir pool/reed pond, river/lake, construction land and unutilized land show the most notable seaward characters; remakable sea-land and altitude gradient characteristics of land use can be found in the zones, mainly presented as the dominanting of land use type changing from reservoir pool/reed pond and construction land to arid land and woodland; the zone 0～6 km away from the coastlines and 10～50 m above sea level has the most prominent significance. Under the background of large-scale coastal development, the research on coastal landscape spatial pattern is important to improve the pattern of coastland development.
