Abstract: At present, when constructing basic farmland protection zone in China, they always pay more attention to the functional quality of basic farmland itself, while ignoring the relationship between basic farmland and supporting infrastructure and ecological land, and lack of awareness of "co-governing, co-construction, and management". There is an increasingly intensified contradiction between the agricultural production and the development of construction land.The quantity,landscape and ecological systerm of basic farmland protection zone have been affected. In order to solve this main contradiction, this paper analyzes the theoretical framework system of the basic farmland protection community, and builds the basic farmland protection zone community vitality evaluation index system, taking Quzhou county, a typical agricultural county in the Huanghuaihai Plain, as the case zone.According to the research path of the basic farmland protection zone community "factor status analysis-community vitality assessment-damaged living body identification-comprehensive management and protection recommendations", the community has conducted a more deep research in the three basic time points of 2009, 2013 and 2017. On this basis, the main conclusions of this paper are as follows:1)In view of the problems existing in the current basic farmland protection, on the basis of domestic and foreign research, the meaning of the basic farmland protectionzone community is defined as a community of life for mutual protection includes basic farmland, basic supporting facilities and small ecological space; 2)Based on the theory of life community, the indicators in the evaluation index system of the basic farmland protection community are divided into four aspects: survivability, development, stability and environmental pressure.Then the analytic hierarchy process is used to determine the level of the indicator system weights; 3)The basic farmland protection zone community is relatively stable and fluctuates between Level II and Level III. In 2009, the evaluation level of Quzhou county basic farmland protection zone community vitality was in the state of Grade III. Except Quzhou Town was in Grade II state, and the rest of the towns and villages were in Grade III state. In 2013, the evaluation of Quzhou county basic farmland protection zone community vitality is in the state of II, Quzhou town, Houcun town, Yanqiao township and Dahedao township are in grade II state, and the remaining townships are in Grade III state; in 2017, the evaluation of Quzhou county basic farmland protection zone community vitality is in Level III, except Quzhou town and Dahedao township are in the second-level state, and the rest of the townships are in the state of Grade III; 4)From the perspective of the spatial distribution of towns and villages, the trend of the level of vitality first rises and then declines during the inter-annual period. In 2013, the level of vitality evaluation was the highest in the township level II, and the distribution pattern of townships along the road network with higher vitality level was presented. The research results can provide a strong basis for strengthening the construction of the basic farmland life community knowledge system and comprehensive land improvement.
