摘要
利用面向对象技术及新型编程语言Java ,在水盐平衡模型基础上 ,通过简化机理模型建立了物理过程模型 ,来模拟土壤水分和盐碱化动态。模型以 1d为步长 ,适合于模拟异质性强的多层土壤水盐动态。利用长岭 1 997年土壤湿度实测资料对土壤水分模型进行了验证 ,模拟结果很理想。模拟了 1 997年羊草及角碱蓬群落土壤盐分、碱化度、pH值动态 ,并与实验资料进行了比较 ,模拟结果可以反映土壤盐分和碱化的季节变化规律。
With the aid of Object oriented design and a new programming language--Java,a physically based model of hydrological saline processes in soil was built on the basis of salt and water balanced model and mechanism model. This model is a daily time step,multiple layer model of soil water salt balance. As a case study of the model,hydrological dynamics of soil in Changling,Jilin province was simulated with results verified to be consistent with the observed soil moisture data in 1997. The dynamics of salt,alkaline and pH was simulated on two types of soil in 1997,with Aneurolepidium chinense and Suaeda corniculata growing on it respectively. Comparing with the experimental data,the simulation results can express the dynamics of saline and alkaline in different seasons.
