The traditional concept of family tree can not reflect the actual characteristics of family tree farm in practice, by comparing the differences in the characteristics of ordinary farmers and family farms, the main characteristics of the family forest farm were sorted out, and the concept of the family tree was reconstructed. Using the opportunity cost theory to establish the model of the most important features of the family tree farm the minimum access standard of the area of the forest land. It analyst the characteristics of several aspects between common present household forest farms and family tree farm , then combined inductive characteristic of the family tree farm, rebuilt the concept of family tree farm, which fixed the deviation between the theory research and practice. It built a model based on the opportunity cost theory, which measures woodland area of minimum access standard. Then set a convenience sample of (Tai Bai) town in Shanxi province measured the woodland area of minimum access standard by using the model. It was found that local family forest woodland area should reach about 2413 mu. It creates a kind of new method and theory through which affirms the family tree farm. The theory and method are provided for the identification of family tree farm in each country.
