یکپارچه‌سازی سیگنال‌های فنولوژیکی و مدیریتی برای نقشه‌برداری زنجبیل در مناطق مختلف با داده‌های چندزمانی سنتینل-۲

Ginger (Zingiber officinale) fields in northern China are often covered by plastic mulch film and shade netting, so Sentinel-2 records management materials as well as the crop canopy. Because these materials and their deployment differ among production systems, models calibrated locally may transfer poorly. We defined three observation windows for the main study counties: spring film mulching, summer shade-net coverage, and autumn exposed-canopy greening. Within each window, spectral bands, v...
