| 摘 要： | 土地适宜性是多级别、多指标模糊评价问题，其模糊性在评价中应予以考虑。可变模糊集方法以可变模糊集理论为基础，通过模型参数的变化，提高评价结果的可靠性。该文在介绍该方法的基础上对长乐市农用土地适宜性等级进行了评价。结果表明该市农用土地适宜性等级介于中度适宜与高度适宜之间，略偏于中度适宜。可见该方法在土地适宜性评价中具有较好的适用性。

| Abstract: | Land suitability evaluation is a multi-grade and multi-index fuzzy evaluation problem. The fuzzy characteristic should be presented in evaluation. Variable fuzzy sets methods are based on variable fuzzy sets theory. Through variability of model parameters, the reliability of evaluation could be enhanced. The agricultural land suitability grade of Changle City was evaluated based on the method theory. Results show that the agricultural land suitability grade of Changle City is between medially suitable and highly suitable with tend to medially suitable slightly. Variable fuzzy sets methods are suitable for land suitability evaluation. |
