长江中下游地区冬闲田地理分布数据

近20年以来，随着中国经济结构的调整和农村劳动力的转移，部分地区冬闲田的面积呈明显增长态势。长江中下游地区冬闲田地理分布数据(WFL_MLYR)是利用长时间序列SPOTNDVI数据，结合研究区耕地空间分布和农作物在出苗期和成熟期NDVI变化特征，基于NDVI动态阈值法提取的。该数据包括长江中下游地区2007年农作物收获时间、2008年农作物播种时间以及2007-2008年冬闲田闲置时间。该数据是掌握中国区域农业生产活动状况，挖掘农业生产潜力，科学、合理及高效利用冬闲田资源，保证农业可持续发展的重要参考数据和基础性数据。

Over the past two decades, alongside the adjustment of China's economic structure and the transfer of rural labor, the area of winter fallow farmland in certain regions has witnessed a notable growth trend. The geospatial distribution dataset of winter fallow farmland in the middle and lower reaches of the Yangtze River (WFL_MLYR) was extracted via long-term time-series SPOT NDVI data, combined with the spatial distribution of cultivated land in the study area, as well as the NDVI variation patterns of crops during the emergence and maturity stages, based on the NDVI dynamic threshold method. This dataset covers the crop harvest timing in 2007, crop sowing timing in 2008, and the idle period of winter fallow farmland during 2007–2008 across the middle and lower reaches of the Yangtze River. This dataset serves as a critical reference and foundational dataset for understanding the status of regional agricultural production activities in China, tapping into agricultural production potential, utilizing winter fallow farmland resources in a scientific, rational, and efficient manner, and guaranteeing sustainable agricultural development.
