Legal system of agro-ecological compensation can not only improve the agricultural production environment,but also provide institutional guarantee for the sustainable development of rural economy. However,some problems existed in legal system of China’s agro-ecological compensation,such as weak systematic legislation,rigid law enforcement operations and lack of effective monitoring mechanisms. Based on the necessity of establishing legal system of agro-ecological compensation and introduction to foreign experience in legal system of agro-ecological compensation,this paper put forward several suggestions on how to establish China’s legal system of agro-ecological compensation: perfecting agricultural eco-compensation-related laws and regulations; building the Multiple Subject (executive subject,compensational subject,paid subject and supervising subject) of legal system in agro-ecological compensation and clearly specifying the rules for operating agro-ecological compensations (optimized compensation standard,specific compensation object,expansion of compensation and increase of compensation funding sources).
