摘要
根据《自然资源调查监测体系构建总体方案》提出以“三调”成果作为自然资源管理的“统一底版”和“唯一底版”的要求,提出了一种以国土调查数据为基础开展湿地资源更新的方法,分别设置标识字段用于记录地表编码与变化情况,同时保留本底数据的关键属性与边界。实验结果表明更新与标识方法可以面向不同管理需求,便捷有效地提取湿地资源数据,同时可快速开展湿地资源流入、流出分析,为自然资源调查监测工作的全面开展提供一种可参考的思路。
According to the requirements of Overall Plan of Natural Resources Survey and Monitoring System Construction,that the third national land survey results should be taken as the“unified plate”and“unique plate”for natural resources management,we proposed a wetland resource update method based on territory survey data,and set up identification fields to record the surface code and changes,while retaining the key attributes and boundaries of background data.The experimental results show that the update and identification method can be tailored to different management needs,conveniently and effectively extract wetland resource data,and rapidly carry out wetland resource inflow and outflow analysis,providing a reference idea for the comprehensive development of natural resource survey and monitoring.
