【摘要】 [目的]探究基于“三生”空间协调与综合质量评价下的永久基本农田布局优化思路及建议。[方法]基于GIS平台，以吉安县作为研究区，构建综合质量评价体系，借助熵值法计算各指标权重，得到耕地综合质量得分，进一步叠加上轮永久基本农田划定成果，基于生态安全、城市建设发展的约束条件下，对初步划定结果进行优化，得到最终布局优化结果。[结果]基于耕地综合质量评价结果，按照耕地质量综合评价得分，得到适宜划入永久基本农田的一般耕地面积为44 560.89 hm~2,考虑原有划定的永久基本农田，坚持生态优先原则，协调城市发展，分为保留、调入、调出3种情况，得到最终永久基本农田优化面积为43 097.52 hm~2。[结论]研究结果遵循了永久基本农田划定优质、聚集和稳定的思路，以及数量不减、质量不降、布局稳定的布局优化要求，可为吉安县永久基本农田布局优化以及高标准农田建设提供一定的参考。更多还原

【Abstract】 [Objective]To explore the idea and suggestion of optimizing the layout of permanent basic farmland based on the spatial coordination and comprehensive quality evaluation of urban, agriculture, ecology.[Method]Based on GIS platform, Ji’an County was taken as the research area, a comprehensive quality evaluation system was constructed, and the weights of each index were calculated by entropy method to obtain the scores of cultivated land comprehensive quality.The results of the upper round permanent basic farmland demarcation were further superimposed.Under the constraints of ecological security and urban construction and development, the preliminary demarcation results were optimized and the final layout optimization results were obtained.[Result]Based on the results of comprehensive quality evaluation of cultivated land, according to the comprehensive evaluation score of cultivated land quality, the general cultivated land area suitable for permanent basic farmland was obtained as 44 560.89 hm~2.Considering the original demarcated permanent basic farmland, adhereing to the principle of ecological priority and coordinating urban development, it can be divided into three situations: reservation, transfer in and transfer out, the optimal final area of permanent basic farmland was obtained as 43 097.52 hm~2.[Conchusion]The research results follow the idea of high quality, aggregation and stability of permanent basic farmland demarcation, and the layout optimization requirements of constant quantity, constant quality and stable layout, which can provide certain reference for the layout optimization of permanent basic farmland and the construction of high standard farmland in Ji’an County.更多还原
