林地数据与国土数据融合方法在林地变更调查工作中的应用--以常州市金坛区为例

Application of Forest Land Data and Land Data Fusion Method in Investigation of Forest Land Change--Taking Jintan District of Changzhou as an Example

林地变更调查是保持林地“一张图”时效性和准确性的重要基础性工作,也是加强林地保护和生态建设的基础支撑。利用国土数据全覆盖、现势性强等特点,在林地变更调查中有效融合国土数据,可以减少管理矛盾,确保林地变更调查数据的权威性。在充分分析林地变更调查背景、林地变更调查基础数据的基础上,采用多元空间数据集成的方法,构建林地数据与国土数据的关联关系,既完成了地类的衔接,也兼顾了林地管理类型的区分,建立了融合技术流程与技术方法,使林地变更调查数据与国土部门土地调查及其变更调查数据进行了有效融合。

Forest land change investigation is an important and basic work to maintain the timeliness and accuracy of“one map”of forest land,and it is alsoa basic support for strengthening forest land protection and ecological construction.Using the characteristics of full coverage and strong current situation of land data,effectively integrating land data in forest land change investigation can reduce management contradictions and ensure the authority of forest land change investigation data.On the basis of fully analyzing the investigation background and basic data of forest land change investigation,this paper adopts the method of multi spatial data integration to construct the correlation between forest land data and land data,which not only completes the connection of land types,but also takes the distinction of forest land management types into account,and establishes the integration technical process and technical method,and effectively integrates the forest land change investigation data with the land investigation and change investigation data of the land department.
