摘要
本文用模糊集方法研究了灌溉工程—渠床土壤透水性的聚类及其空间分布(相似性)特征,有助于增加传统土壤与地质剖面制图描述的定量成分及对该系统结构规律(连续性)的揭露。也从另一角度对土壤空间变异性作了一种新的补充。为渠道理论输水损失水量计算提供了土壤透水性单元聚类图、模式样本及入渗总水量的模式样本的数学模型。
A fuzzy system,the grouping of soil permeability in the canal bed and its spacial distribution characters,was studied with the fuzzy sets method in an attempt to add quantitative analysis into the traditional soil profiling method,so that the structured laws of this system were understood better. The study was complemented in the spatial variability of soil.It supplied the soil permeability unit grouping figure,sampling pattern and mathematical model of sampling pattern of total infiltration quantity for estimating the theoretical conveyance canal losses.
