30m resolution crop classification dataset in Northeast China (2020)

a. Data content (data file/table name, including observation indicators) This dataset includes the distribution data of basic crops in Northeast China in 2020, reflecting the planting situation of major crops in Northeast China. It can provide data support for research on changes and adjustments in planting structure. b. Construction purpose The crop planting structure refers to the main types of crops and their spatial distribution in a region. It is an important reference for monitoring crop growth and adjusting agricultural structure. Timely and accurate information on crop spatial distribution and suitability planting can be obtained through land classification and crop suitability evaluation, which is of great significance for crop yield monitoring, fine management of agricultural water use, regional agriculture, sustainable development, etc. c. Service target It can serve a wide range of scientific and technological workers, government management agencies, and public welfare environmental organizations in disciplines such as geography, ecology, agriculture, and agroecology. d.
