统计分析软件FORSTAT的设计与应用

Design of a statistical and analytical software——FORSTAT and its application.

林业信息数据的复杂性 ,决定了研制具有自主知识产权的林业统计分析软件的必要性 .该文在进行系统需求分析的基础上 ,以IBM PC系列程序集为原型 ,加入许多近代的统计方法 (包括似乎不相关模型、联立方程组模型、混合模型和度量误差模型等 ) ,运用组件对象模型技术 ,从统计功能模块划分、用户界面设计和开发环境选择等3个方面 ,对具有林业特色的统计分析软件FORSTAT进行了设计 .用树干解析为例 。

The complexity of forest information makes it indispensable to design and to develop a software with our own intellectual property for forestry statistics and analysis. After the analysis on system demands, based on the IBM-PC serial programming package, adding many modern statistical methods including seemingly unrelated models, simultaneous equations models, mixed models, measurement error models and so on, and using COM technology form three aspects: division of statistical function modules, design of user interfaces, selection of development environment, an overall design of statistical software with forestry characteristics, FORSTAT, is made. Taking the stem analysis as an example, the application of FORSTAT is introduced.
