通用森林样地调查统计分析系统设计与开发

Design and Development of Universal Forest Sample Plot Statistical Analysis System

森林样地调查统计分析是林业生产和科研中的一项基础性工作。由于专业性较强、区域差别大,需要有通用的计算和统计工具进行支持。在需求分析基础上,设计了通用样地统计分析系统。基于VB6.0和Microsoft Office Access开发,实现了样地数据管理、样地数据查询、样地统计(包括一般因子统计、径级统计和树高级统计)、林木空间位置分布图、林分统计图表等多项功能。系统在开发过程中采用了交互设计的理念,具有灵活性和通用性等特点。可作为林业生产和科研中的一个工具软件。

Statistical analysis on forest sample plots is considered as a fundamental work of forestry production and research. Generalized tools are needed to provide supports for computation and analysis because of the specialty and regional variability of forestry. Based on the user requirements, designed the system of universal forest sample plot statistical analysis. This system is developed through VB 6.0 and Microsoft Office Access, and realized functions including plot data management, plot data inquiry, computation of plot statistics （basic plot statistics and advanced plot statistics by diameter and tree height class）, histograms of diameter and height distributions and tree spatial distribution map. It employed an interaction design idea in the process of system development, whieh made the system more flexible and general. This system can be tool software in forestry production and research.
