A field parcel dataset in China main cultivating area.

This dataset spans among Heilongjiang, Shandong, and Zhejiang provinces, China, which are representative of the diverse farming patterns encountered across the 
major agricultural regions of China. These three provinces span a latitudinal range of approximately 25 degrees, where the distribution pattern of cultivated land gradually transitions from large-scale, regular parcels in the north to fragmented, irregular patterns in the south. Additionally, these regions contain diverse arable land types, including black soil, loess, and paddy fields, exhibiting distinct spectral reflectance characteristics in remote sensing imagery.
