| 摘 要： | 本文运用地质数学、土壤科学与水科学的交叉和综合理论，在充分考虑土壤水资源信息分布的随机性和结构性的基础上，将新兴的地质统计学理论与经典统计学理论结合用于水—土科学。利用土壤水资源信息的地质学结构特征，对大面积土壤墒情区域分布预测；在模糊聚类分析基础上，利用ＣＡＭＳ系统绘制土壤墒情区域最优分布图。完成了西辽河６５１００ｋｍ２范围内的大面积土壤墒情区域预测与利用土壤水动力学原理对不同时期（季节）的土壤墒情的区域预报。为灌区土壤水分监测预报与抗旱排涝决策和防灾抗灾提供宏观决策依据。

| Abstract: | Using the intersectional and synthetical theories between geostatistics,soil science and water science,the geostatistics are combined with classical statistics into the soil-water science based on the full considering the randomness and structure of soil water resources information (SWRI) in this paper.The authors make full use of geological structural characteristics of SWRI to estimate the regional distribution of soil moisture in a large area.The regional optimal distribution of soil moisture maps are drawn by CAMS accordering to the fuzzy grouping analyses of SWRI.The soil moisture of large area of 65100km 2 in Xiliaohe Plain are estimated and predicated in different periods or season according to soil hydraulic dynamics.That can be a guide to moitor and predicate soil moisture and prevent and fight nutural adversities in irrigagion district. |
