    Abstract:

    Cultivated land(CL) resource is an important resource for human survival and development, and it bears the function of ensuring food security and social stability. The research on the value evaluation of CL resources provides a theoretical basis for the protection of CL, and has important practical significance. With the scarcity of ecosystem services become more and more prominent, the ecological value (EV) evaluation of CL has received unprecedented attention.This paper explored the research advances and perspectives of evaluation on EV of CL. Firstly, the current value of CL classification system and the connotation were summarized. The research of the CL resources value has experienced the development process from the value of no value to a single value then to the comprehensive value accounting at home and abroad, and scholars focused on how much food and how many people will be able to produce, and gradual transition to the economic output value of the cultivated land, the social security function and the value of ecological services, the EV of CL were defined on the basis of the study above. Secondly, the accounting methods of EV of CL were summarized at home and abroad, including equivalent value correction method, substitute market method and simulation market method, and the advantages and disadvantages of each method were summarized. Finally, this paper put forward the focus of future research about EV evaluation of CL,including the follows: research on EV system of CL, the EV of CL evaluation method research, the EV refinement and evaluation of CL and in the ecocompensation for CL in applied research.The research results and conclusions had great significance for the theory and method of the EV evaluation of CL.
