甘肃省2013-2017年25万森林植被类型分布图

该数据为甘肃省2013-2017年25万森林植被类型空间分布数据。数据来源于中国林业科学研究院资源信息研究所中国森林植被调查项目。项目基于部分历史植被分布图、历史森林分布图、2012年TM、90年代TM数据、25万DEM数据、野外样地调查数据等，并严格按照《森林植被分类、调查与制图规范》（2019）的相关规程加工获取。数据为矢量数据，包括省市、区县、林纲组、林纲亚组、林纲、林目组、林目亚组、林目、林系组、林系亚组、林系等属性字段。数据比例尺为1:25万。该数据为森林资源调查、规划设计等提供数据支撑服务。

This dataset provides spatially distributed data of forest vegetation types in Gansu Province from 2013 to 2017. It originates from the China Forest Vegetation Survey Project of the Institute of Forest Resources and Information Technology, Chinese Academy of Forestry. The project was developed based on multiple data sources including partial historical vegetation distribution maps, historical forest distribution maps, 2012 TM imagery, 1990s TM imagery, 1:250,000 DEM data, and field plot survey data, and was processed strictly in accordance with the relevant provisions of the *Specification for Forest Vegetation Classification, Survey and Mapping* (2019). The data is in vector format, with attribute fields including province, city, district, county, forest class group, forest class subgroup, forest class, forest order group, forest order subgroup, forest order, forest series group, forest series subgroup, and forest series. It has a scale of 1:250,000, and provides data support for forest resource surveys, planning and design, and other related applications.
