摘要

在吉林省大安市进行生态环境调查的基础上

进行了土壤理化性质和营养成分的系统测试

选择了土壤的有机质、全氮、全磷、全钾、有效氮、速效磷、速效钾7项测试数据作为土壤养分的评价指标

采用物元和可拓理论构建区域土壤养分评价模型

对大安市的土壤养分进行评价。评价结果符合当地实际情况。物元模型可以消除评价过程中人为因素的影响

提高评价精度

是进行土壤养分评价的理想方法。

Abstract

Parameter determination is the prerequisite for the simulation of rainfall and runoff in a hydrological model. Model and parameter uncertainty should be considered during that procedure. This paper started with an introduction of the theory on the multi2objective complex evolution (MOCOM-UA) algorithm of excellent global and local optimization capability for dealing with the complex problem of hydrological model calibration. Based on the Xin’ anjiang model

different searching mechanisms between the multi-objective approach based method and genetic and simplex algorithm were respectively discussed by rainfall-runoff simulations for the Baohe watershed in the upper reaches of the Hanjiang River basin. With the application of the multi-objective genetic algorithm coupled with the simplex method as an optimal solution

the Pareto space of parameters and the prediction extent of the model were calculated and analyzed under four objective function conditions. The uncertainties of the model and its parameters were preliminarily investigated.
