摘  要:本文以森林资源状况调查为研究主体,探讨自然资源统一确权登记工作中森林资源调查这一类型自然资源状况调查的有效方法。森林资源调查基于GIS技术以“国土三调DLTB层”数据为基础底图,“林业一张图”数据作为属性参考图,叠加高分辨率遥感影像进行地类对照。由于国土三调图斑与森林资源管理“林业一张图”数据分类标准不一致,且图斑相交时会出现不同属性值情况,导致森林资源图斑属性填写有一定困难。本文针对这一问题给予相应对策建议,旨在为自然资源统一确权登记森林状况调查进行有益探索,为后续工作形成可复制、可推广的调查体系。

Abstract: Based on the investigation of forest resources, this paper discusses the effective method of forest resources investigation in the unified registration of natural resources. Forest resources survey is based on GIS technology, taking "DLTB layer" data of the third national land survey project as the base map, and "one map of forestry" data as the attribute reference map. Due to the inconsistency between the data classification standard of the land three adjustment map and the forest resource management map, and the different attribute values when the map intersects, it is difficult to fill in the attribute of the forest resource map. In this paper, the corresponding countermeasures and suggestions are given for the purpose of beneficial exploration for the unified forest status investigation of natural resources registration, and forming a replicable and and popularized investigation system for follow-up work.

Key Words: Unified right confirmation and registration of natural resources; The third national land survey; A map of forestry; Forest resource patches

認真贯彻落实习近平总书记关于自然资源管理重要论述,推进“绿水青山”向“金山银山”转变,明确自然资源的登记范围,近年来全国各地陆续启动自然资源统一确权登记工作,做到全部国土空间各类自然资源资产的产权主体界定清晰。自然资源统一确权登记自然资源登记单元类型划分海域、无居民海岛、自然保护地、水流、国务院确定的重点林区、湿地、草原、荒地、森林和探明储量的矿产资源10个类型,其中自然保护地和水流自然资源还分有二级类型,每类登记单元对应不同的编码,如表1所示。划分则突出山水林田湖草是一个生命共同体的理念,体现资源及权属的科学性和系统性[1]。……
