基于Yaahp软件的AHP法区域农用地整理潜力评价研究——以四川省南充市嘉陵区为例

On the Rearrangement Potentiality of Regional Agricultural Land Based on the AHP Method by Yaahp Software: a Case Study on Jialing District

笔者研究农用地整理潜力的影响因素.采用基于Yaahp软件实现的层次分析法(AHP)和文献资料法,得出影响嘉陵区农用地整理潜力大小的因素是荒草地面积、田坎系数、沟渠面积、作物单产量、水利设施覆盖率和水土流失率,作物单产量和水利设施覆盖率两个指标为逆指标,即两者越大,整理的潜力可能越小.揭示川中丘陵地区应该综合荒草地面积、田坎系数、沟渠面积、作物单产量、水利设施覆盖率和水土流失率六大因素来评价区域农用地整理的潜力大小,从而为区域进行农用地整理提供科学依据.

The purpose of the study is to analyze the impact of the rearrangement potentiality of the regional agricultural land. AHP method based on the yaahp software and documentation ＇s employed. The paper presents that the influence factors of regional agricultural land rearrangement include ditch area, water conservancy facilities coverage area, the yield of crops per unit area, grassland area and the soil erosion rate. Water conservancy facilities area and the yield of crops per unit area are two inferior indexes, namely the values are bigger, the potentiality may be smaller. The paper points out that hilly area in the Northeastern of Sichuan should be evaluated by the six factors to size the regional agricultural land rearrangement potentiality, providing the scientific basis for the regional agricultural land rearrangement.
