摘 要: 耕地的适宜性评价是合理利用耕地的重要前提 .该文中采用物元模型进行土地适宜性评价 ,不仅可以克服在评价过程中人为因素的影响 ,而且可对参评因子进行量化处理 ,从而提高土地适宜性评价的精度 .该文中选取长乐市某区域为评价样区 ,应用物元模型对其耕地适宜性进行了评价 ,研究结果表明该样区土地适宜性等级为中等适宜 ,与实际相符 ,表明了物元模型在土地适宜性评价中的可行性 . The premise of proper usage of arable land is to setup on the base of land suitability evaluation . The matter element module is applied to the arable land suitability evaluations in this paper. It not only overcomes the effect of man-made factors, but the factors that are concerned will be dealt with quantity. Consequently , the precision of land suitability evaluation could be improved. A land unit of Changle City in Fujian Province is chose as case study of land suitability evaluation based on matter element module. Result of evaluation indicates that land suitability of the case of Changle City is moderate evaluation, which indicates matter element module is feasible for land suitability evaluation.
