1990年三江平原30 m分辨率湿地水禽栖息地适宜性评价数据集

1990年三江平原30 m分辨率湿地水禽栖息地适宜性评价数据集，反映了1990年三江平原水禽栖息地适宜性状况。三江平原是水鸟最重要的栖息地之一，其生态系统受到了严重的破坏，尤其是由于人为干扰和气候变化造成的湿地流失和草原退化。这些事件导致水鸟种类和整体数量明显减少。定期、及时监测水鸟生境适宜性的变化，了解其潜在的驱动因素是维护区域生态安全的关键。可广泛服务于地理学、湿地生态、环境保护等相关学科的科学研究工作者。

The 30 m-resolution Wetland Waterfowl Habitat Suitability Assessment Dataset of the Sanjiang Plain in 1990 reflects the habitat suitability status of waterfowl in this region during 1990. As one of the most critical habitats for waterbirds, the Sanjiang Plain's ecosystem has suffered severe damage, notably wetland loss and grassland degradation driven by human disturbances and climate change. These disturbances have caused a marked reduction in both waterbird species richness and total population size. Regular and timely monitoring of changes in waterfowl habitat suitability, as well as elucidation of its underlying driving forces, are critical for safeguarding regional ecological security. This dataset can be widely utilized by scientific researchers across related disciplines including geography, wetland ecology, and environmental protection.
