| 摘 要： | 基于模块化和面向对象化程序设计思想，根据土壤水分平衡过程和作物生长发育的特点，采用VisualBasic程序设计语言，实现了界面友好的土壤水分平衡与作物生长模拟模型。在土壤、作物和气象参数数据文件的支持下，对红壤性水稻土上的作物生长过程进行了模拟和验证，田间验证结果表明，冬小麦田间0～5，5～15，30～35cm三个土壤深度土壤含水量模拟值与实测值相对误差分别为7．0％、8．1％、4．5％。小麦、早稻、晚稻、玉米产量模拟值与实测值之间的相对误差分别为6．7％、2．4％、5．3％、1．9％。 |

| Abstract: | On the basis of Modularization Design and Object Oriented Programming concept,according to the characteristics of soil water process and crop growth,making use of Visual Basic language,soil water balance and crop growth simulation model with user-friendly interface was developed.Having soil parameters,crop parameters,weather data,the simulation system was verified in red rice soil.The results of field verification show that the relative errors between simulated and observed soil water contents in the layers of A(0~5 cm),B(5~15 cm),C(30~35 cm) in the winter wheat field are 7.0%,8.1%,4.5%,respectively.The relative errors between simulated and observed crop yield of wheat,early rice,late rice and maize are 6.7%,2.4%,5.3%,1.9%,respectively. |
