中国区域250米归一化植被指数数据集（2000-2024）

该数据集是中国区域2000至2024年月度归一化植被指数产品，空间分辨率250米，合成方式采用月最大值合成，每年12期，共299期。本产品是基于Aqua/Terra-MODIS卫星传感器MOD13Q1产品以及土地利用数据，经单期影像同类地物噪声像元初步重建、长时间序列影像S-G滤波、保留高质量像元、16天合成月度产品及中国范围拼接等过程生成。该数据集能够为全国区域生态质量评价、重要生态空间调查评估等工作提供数据参考。

This dataset is a monthly Normalized Difference Vegetation Index (NDVI) product for China spanning from 2000 to 2024, with a spatial resolution of 250 meters. The synthesis method adopts the monthly maximum value composite approach, with 12 periods per year, totaling 299 periods in total.

This product is generated based on the MOD13Q1 product from Aqua/Terra-MODIS satellite sensors and land use data, through processes including preliminary noise pixel reconstruction for homogeneous land cover features in single-temporal images, Savitzky-Golay (S-G) filtering for long time-series imagery, retention of high-quality pixels, generation of monthly products from 16-day composites, and mosaic across the entire Chinese territory.

This dataset can provide reliable data references for regional ecological quality assessment, important ecological space investigation and evaluation, and other relevant ecological research and management works.
