摘要/Abstract

摘要：

【目的】针对我国南方地区云雨频繁、耕地细碎及多熟种植所造成的耕地种植强度（cropping intensity，CI）提取与动态监测不确定性问题，拟充分发挥多尺度遥感观测的优势，实现2000—2021年湖北省耕地CI的高效精准提取，并解析区域农业生产格局的时空演变规律。【方法】协同250 m MODIS 归一化差值植被指数（NDVI）和30 m Landsat NDVI时序数据，分别利用STARFM、ESTARFM、STNLFFM和GF-SG 4种典型的时空融合算法生成高时空分辨率NDVI数据，从光谱保真度（AD/RMSE）、空间细节精度（Edge/LBP）及CI提取效果对融合数据进行综合评估。利用优选的时空融合算法生成2000—2021年湖北省30 m/8 d时空分辨率NDVI数据集，并基于物候的峰值探测法，开展长时序耕地种植强度提取及时空演变分析。【结果】与其他3种时空融合算法相比，GF-SG算法在光谱保真度与空间细节精度方面表现最佳（|AD|<0.021，RMSE<0.111，|Edge|<0.55，|LBP|<0.10），利用该算法重构的NDVI时序数据集提取耕地CI的精度提升了0.02%—5.53%。基于地面实地采样数据开展精度评价，湖北省耕地CI分类的总体精度达86.60%。2000—2021年耕地CI时空演变分析显示，研究区每5年约有20%—25%的耕地发生种植强度转变，其中2005—2010年变动最显著（25.79%），2010—2015年变动最小（20.07%）。主导转变类型由“一熟转二熟”（13.49%）逐步演变为“二熟转一熟”（9.35%）和“一熟转休耕”（4.90%）。【结论】近20年来湖北省形成以“一熟为主、二熟与休耕共存”的多元耕作格局，耕地CI演变由政策引导、劳动力变化、资源投入与种植结构调整等因素共同驱动。通过协同MODIS与Landsat多尺度遥感数据构建的高时空分辨率NDVI数据集，可有效支撑复杂农业景观下长时序耕地CI的高效精准提取，可为农业生产管理与耕地保护政策制定提供重要支撑。

Abstract:

【Objective】 To address the uncertainty in the extraction and dynamic monitoring of cropland cropping intensity (CI) caused by frequent cloud cover, fragmented farmland, and multi-cropping systems in southern China, this study aimed to fully leverage the advantages of multi-scale remote sensing observations to achieve efficient and accurate CI mapping for Hubei Province from 2000 to 2021, and to analyze the spatiotemporal evolution of regional agricultural production patterns. 【Method】 Time-series NDVI data from 250 m MODIS and 30 m Landsat were integrated using four representative spatiotemporal fusion algorithms: STARFM, ESTARFM, STNLFFM, and GF-SG. Fusion performance was comprehensively evaluated based on spectral fidelity (AD, RMSE) and spatial detail accuracy (Edge, LBP). The optimal algorithm was used to generate a 30 m/8-day NDVI dataset for 2000-2021. Cropland CI was extracted using a phenology-based peak detection method, and then its spatiotemporal variation was analyzed. 【Result】Compared with the other three spatiotemporal fusion algorithms, the GF-SG algorithm demonstrated the best performance in both spectral fidelity and spatial detail accuracy (|AD|<0.021, RMSE<0.111; |Edge|<0.55, |LBP|<0.10). The reconstructed NDVI time series using this algorithm improved the accuracy of cropland CI extraction by 0.02%-5.53%. Based on ground samples, the overall classification accuracy of cropland CI in Hubei Province reached 86.60%. From 2000 to 2021, approximately 20%-25% of croplands in the study area experienced CI transitions every five years, with the most significant changes occurring between 2005-2010 (25.79%) and the least between 2010-2015 (20.07%). The dominant transition type shifted from 'single-cropping to double-cropping' (13.49%) in the early years to 'double-cropping to single-cropping' (9.35%) and 'single-cropping to fallow' (4.90%) in the later years. 【Conclusion】Over the past two decades, Hubei Province has developed a diversified cultivation pattern dominated by single cropping, with coexistence of double cropping and fallow practices. The evolution of cropland CI has been jointly driven by policy guidance, labor force changes, resource input, and adjustments in cropping structure. By integrating multi-scale remote sensing data from MODIS and Landsat, this study constructed a high spatiotemporal resolution NDVI dataset, which enabled efficient and accurate extraction of long-term cropland CI in complex agricultural landscapes. The findings offered the critical support for agricultural production management and the development of cropland protection policies.

	均方根误差 RMSE	[0,1]	数值越大，表示融合图像的光谱误差越大 A larger value indicates greater spectral error in the fused image
	平均差异 AD	[-1,1]	数值0代表精准的融合影像 A value of 0 indicates a precise fusion image
			负值表示融合影像中光谱信息的低估 A negative value indicates an underestimation of spectral information
			正值表示融合影像中光谱信息的高估 A positive value indicates an overestimation of spectral information
空间 Spatial accuracy	边缘特征 Edge	[-1,1]	值0代表精准的融合影像 A value of 0 indicates a precise fusion image
	边缘特征 Edge	[-1,1]	负值越大，表示融合影像中的边缘特征过度平滑 A large negative value indicates over smoothing of edge features in the fused image
	局部二值模式 LBP	[-1,1]	正值越大，表示融合影像中的边缘特征过度锐化 A large positive value indicates over sharpening of edge features in the fused image
