环北极不同类型多年冻土区NDVI变化数据集（1982-2015）

环北极不同类型多年冻土区NDVI变化数据集（1982-2015），时间分辨率为每5年一期，覆盖范围为整个环北极国家, 空间分辨率为8km,以多源遥感、模拟、统计和实测数据为基础, 使用GIS方法和生态学方法结合, 量化了北半球多年冻土对生态系统的调节服务功能, 其所有数据进行了质量控制。利用环北极不同类型多年冻土区划，借助1982-2015年期间NDVI值，使用GIS方法，计算了1982-2015年期间环北极不同类型多年冻土区的NDVI变化，形成了“1982-2015环北极不同类型多年冻土区NDVI变化数据集”。同时，综合多个文献，对其数据进行了质量控制。

NDVI Change Dataset for Different Types of Permafrost Regions around the Arctic (1982-2015) has a temporal resolution of 5-year intervals, covers all Arctic-rimmed countries, and has a spatial resolution of 8 km. Based on multi-source remote sensing, modeling, statistical and field-measured data, this dataset combines GIS and ecological methods to quantify the regulating ecosystem services of permafrost in the Northern Hemisphere, with all data undergoing quality control. Using the Arctic permafrost zoning classification for different types and NDVI values from 1982 to 2015, we calculated the NDVI changes in different permafrost regions around the Arctic during 1982-2015 to develop the "NDVI Change Dataset for Different Types of Permafrost Regions around the Arctic (1982-2015)". Meanwhile, its data were further quality-controlled by integrating multiple academic literatures.
