- Abstract:

The purpose of this research is to conduct evaluation of spatial distribution of basic farmland conservation area in order to provide guidance and reference for a new round of land reclamation planning and high-standard basic farmland construction carried out scientifically. Methods are based on fuzzy weight of evidence model. The results showed that:(1) fuzzy weight of evidence model, which is both data-driven and knowledge-driven, could give full play to the prior knowledge and information in the raw data, could overcome the subjectivity factor screening and weight calculation, simple algorithm, easy to operate, making the evaluation results objective and reasonable;(2) 86.52% of the known suitable points were above moderately suitable level in the grading figure of modified posterior probability, reflecting the high coherency, which indicated that the fuzzy weight of evidence connecting with modified posterior probability could evaluate the suitability of the spatial distribution of basic farmland protection areas scientifically and effectively; (3) based on the fixed obvious turning points of posteriori probability frequency distribution, the study area was divided into four levels:highly rational zone, moderate rational zone, approaching reasonable zone, unreasonable zone, reasonable area accounted for 94.73% of basic farmland protection areas, which meant that the current planning scheme was basically rational. This paper provided a method for the evaluation of basic farmland protection areas and the basis for the adjustment of the late prime farmland. The research results could provide a method reference to carry out the quick and effective evaluation of the reasonableness of the basic farmland protection areas latter, improve the basic farmland protection area layout rationality, and promote sustainable development.
