以第三次国土调查成果为森林资源"一张图"细化调查基础底图数据融合技术路线的探讨

在自然资源统一调查监测的大背景下,以第三次国土调查成果(以下简称“国土三调”)作为基础底图,推进相关自然资源专项调查是大势所趋。山东省2020年森林资源管理“一张图”(以下简称“一张图”)更新调查以“国土三调”成果作为基础底图,探索了基础调查和专项调查在技术路径上的融合衔接。本文通过研讨融合衔接的技术路线以及遇到的具体问题,分析了以“国土三调”为基础底图推进“一张图”细化调查的必要性和可行性,为自然资源统一调查监测进行了有益探索。

Discussion on Technical Route of Refining the Base Map Data Fusion Based on the Results of the Third Land Survey as "one map" of Forest Resources

Under the background of unified investigation and monitoring of natural resources, it is the general trend to promote the special investigation of related natural resources with the results of the third land survey as the basic map. The "one map" update survey of forest resources management in Shandong province in 2020 takes the results of "three land transfer" as the basic map, the integration and convergence of basic investigation and special investigation in the technical path has been explored, and has been verified in Xidong town of Zouping county in Binzhou ciy. By discussing the technical route of integration and convergence and the specific problems encountered, the necessity and feasibility of promoting the detailed investigation of "one map" based on the "three land transfer" as the base map has been verified, and makes a beneficial exploration for the unified investigation and monitoring of natural resources.
