| 摘 要： | 列出了我国南方水稻产区１６种具有代表性的水田土壤及其特征参数，探讨了基于模糊数学原理由土壤含水量和机械组成来预测任一种水田水壤强度（内聚力系数和内摩擦因数）的可能性，得出了预测公式并给出了预测实例，结果表明，该方法具有一定的可行性。

| Abstract: | Sixteen samples representing various paddy field soils of the main rice planting regions in South China, with their characteristic parameters, are listed. Based on those data the soil strength of any other paddy field soil can be fuzzily predicted when its water content, sand content and clay content are given. Illustrative examples show that the predicted result seems to be acceptable in engineering practice although there are some differences between predicted and measured results in some cases. |
