We have developed a plant growth model simulation execution system based on the WWW (World Wide Web) and tested it using several plant growth models. Most legacy growth simulation models were described in high-level computer languages and/or in simulation languages. Since each model has its own calculation algorithm and complicated subroutines, it is difficult to translate a model source program into another language. In our system, a simulation program is compiled and executed using its original language. CGI (Common Gateway Interface) programs written in C language on a WWW server provide user interface between the client and a simulation model program, and create intermediate input/output text files. The simulation program reads input data from the input file and writes calculation results into an output file. This procedure works simply, and a modification of input/output routines does not require a complete understanding of the source program. A field lettuce growth model written in C, a hydroponic lettuce growth model in Pascal, and a general-purpose growth model for six crops in Fortran and CSMP were implemented using the system. The input/output routines of the source programs were comprised of 20 to 30 lines and were easily modified. This system was implemented on a Microsoft Windows WWW server. The simulation programs could be executed without any programs in the system. We also developed a JavaServlet based plant growth simulation execution system.

我们已经开发了一个基于WWW（万维网）的植物生长模型模拟执行系统，并使用几种植物生长模型进行了测试。大多数传统增长模拟模型都是用高级计算机语言和/或模拟语言描述的。由于每个模型都有自己的计算算法和复杂的子程序，因此很难将模型源程序翻译成另一种语言。在我们的系统中，一个模拟程序的编译和执行使用其原始语言。在WWW服务器上用C语言编写的CGI（CommonGatewayInterface）程序提供客户端与仿真模型程序之间的用户接口，并生成中间输入/输出文本文件。模拟程序从输入文件读取输入数据，并将计算结果写入输出文件。这个过程工作简单，修改输入/输出例程不需要完全理解源程序。用C语言编写了田间生菜生长模型，用Pascal语言编写了水培生菜生长模型，用Fortran和CSMP语言编写了6种作物的通用生长模型。源程序的输入/输出例程由20到30行组成，很容易修改。该系统是在Microsoft Windows WWW服务器上实现的。仿真程序可以在没有任何程序的情况下执行。我们还开发了一个基于JavaServlet的植物生长模拟执行系统。
