重点区域旗舰物种分布图集（2020版）

数据主要包括“一带一路”沿线国家和重点区域的旗舰物种的面（POLYGON）、点（POINT）位分布，数据来源IUCN、GIBF。分布图制作的基础数据底图来源于ArcOnline地图下载。本数据主要用于分析“一带一路”重点区域旗舰物种的空间布局。
1）数据内容：本数据集按“一带一路”重点区域（中亚大湖区、中巴经济走廊、三江源国家公园）旗舰物种分布集成，其中哺乳动物9种、高等植物与真菌15种、鸟类20种、鱼类3种。
2）数据来源及加工方法：基于“一带一路”重点区域的旗舰物种名录及其分布基础数据：包括IUCN红色名录以及GBIF的物种地理空间数据，运用AcrMap软件制作每个物种的分布图，形成图集。
3）数据质量描述：每个物种经严格的文献调查、野外调查等，确定旗舰标准，并经哺乳动物学专家、高等植物学与真菌学专家、鸟类学专家、鱼类学专家，按“旗舰物遴选标准（6个指标中，应至少同时具有其中4个指标）”原则严格筛查打分，遴选出评分＞25分的物种进行图集制作。每个物种的地理空间数据的经纬度信息经专业人员核对，并按统一的制图标准制作出图。
4）数据应用成果及前景：考察了“一带一路”重点区域旗舰物种的生存状况、生态价值、人文经济价值等，为“泛第三极环境变化与绿色丝绸之路建设”地区的生态多样性评估和生态保护提供科学依据。

This dataset primarily contains polygon (POLYGON) and point (POINT) distribution records of flagship species in countries and key regions along the Belt and Road Initiative (BRI). The data sources are the International Union for Conservation of Nature (IUCN) and the Global Biodiversity Information Facility (GBIF). The base map for distribution map production was downloaded from ArcOnline. This dataset is mainly used to analyze the spatial distribution of flagship species in key BRI regions.

1) Data Content: This dataset integrates the distribution data of flagship species in key BRI regions, including the Central Asia Great Lakes Region, China-Pakistan Economic Corridor (CPEC), and Sanjiangyuan National Park. It includes 9 mammal species, 15 higher plant and fungal species, 20 bird species, and 3 fish species.

2) Data Sources and Processing Methods: Based on the flagship species list and their underlying distribution data for key BRI regions, including the IUCN Red List and geospatial species data from GBIF, ArcMap software was used to create distribution maps for each species, forming a comprehensive atlas.

3) Data Quality Description: For each species, strict literature reviews, field surveys and other investigations were conducted to determine the flagship eligibility criteria. Subsequently, mammalogists, botanists and mycologists, ornithologists, and ichthyologists conducted rigorous screening and scoring in accordance with the principle of "flagship species selection criteria (at least 4 out of 6 indicators must be satisfied). Species with a score greater than 25 were selected for atlas production. The latitude and longitude information of each species' geospatial data was verified by professional personnel, and maps were produced in accordance with unified cartographic standards.

4) Data Application Achievements and Prospects: This dataset has been utilized to investigate the survival status, ecological value, humanistic and economic value of flagship species in key BRI regions, providing scientific support for biodiversity assessment and ecological conservation in the regions related to "Pan-third Pole environmental changes and the construction of the Green Silk Road".
