China has one-fifth of the world's population but only less than 8% of the cropland area. The large population needs a sustainable food supply. China’s special national background of less arable land resources demands high standards on cropland protection. Most of the prior research is focused on the cropland health, such as cropland disease, cropland quality, soil health, ecosystem health. Although many researchers have proposed different solutions to the "disease" of the cropland, this issue has not been effectively addressed. Cropland is a complex system with a series of internal components interconnected. The system includes internal changes of its components and the uncertainties between humanity and environment interactions. This paper will define cropland system health, identify the threshold and give advise to keep the health condition or recover the cropland system.
