Most of China's major grain-producing areas rely on irrigated agriculture, and the canal system is the infrastructure that delivers irrigation water from the water source to the field. The land is the carrier that supports crop growth. Administrative division, irrigation area division, ownership information, planting structure, and irrigation water source are important associated information of the land.
