林草湿与“三调”数据融合研究--以江苏省连云港市赣榆区为例

Data Fusion for Forest-Grassland-Wetlandin the Third National Land Survey:A Case Study of Ganyu District,Lianyungang City,Jiangsu Province

基于连云港市赣榆区2020年森林资源管理“一张图”、国土“三调”数据,利用ArcGIS软件将“一张图”与“三调”数据叠加分析,在厘清林地、草地、湿地与其他土地范围界线的基础上,结合遥感技术对林草湿初步融合图斑进行属性更新,形成赣榆区林草资源“图数库”。针对此结果分析原因并提出建议,以期为今后自然资源的管理与决策提供理论依据。

A Graph database was constructed for the forest and grass resources in Ganyu District,Lianyungang City,Jiangsu Province,China.The image data was firstly collected from the“One Map”project of the forest resources planning in 2020,according to the third national land survey.ArcGIS software was then used to overlay the datasets,in order to clarify the land boundaries of the woodland,grassland,wetland,and the rest land.The initial forest-grassland-wetland fused map was also obtained to update the attributes of forest-grassland wetland using remote sensing technology.Finally,the new graph database was achieved for the forest-grassland resources in the study area.Some influencing mechanisms and recommendations were proposed during this time.The finding can also provide the theoretical basis for the land use management and decision making on the natural resources planning.
