Design and Development of Universal Forest Sample Plot Statistical Analysis System

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,which made the system more flexible and general.This system can be tool software in forestry production and research.
