摘要: 在分析1998年霍林河流域特大洪水特点的基础上,选择下垫面控制因子和复合控制因子两组变量进行了因子分析,求解出每组变量的数学表达式,继而进行了尖点突变模拟和洪水后水环境突变态的分区,划分为稳定区、潜在突变区和突变区,这对合理开发该区的水、土、生物资源,预防洪水灾害有重要意义,并为研究洪水对环境的突变影响提供了一种新的模式。

Abstract: On the analysis of characteristics of tremendous flood in the Huolin River in 1998, two variables that include underlying surface cotroled factors and compound controled factors have been selected and mathmatics expression of each variable has achieved using factor analyses. Then the model of needle mutation has been simulated and mutation rigion of water environment have been classed after flood. The study has an important significance for developing reasonable natural resources and defensing flood disaster. It provides a new model to study the influence of environmental mutation after the tremendous flood.
