<正>介绍了数据融合技术的基本概念和内容，分析了该技术在森林防火、森林蓄积特征的估计和更新、森林资源调查等方面的应用，提出该技术可应用于木材无损检测及精确林业。融合机器视觉、X射线等单一传感器技术检测木材及木制品，可以更准确地实时检测出木材的各种缺陷；集成GPS、GIS、RS及各种实时传感器信息，利用智能决策支持系统以及可变量技术，能够实现基于自然界生物及其赖以生存的环境资源的时空变异性的客观现实，建立基于信息流融合的精确林业系统。

This paper selected Jiangxi province as a case, making use of the computer and GIS,discussing the techniques for building up the 1 : 1 000 000 country red soil information system,and also normalizes the code of soil type and soil attribute data of Jiangxi province’s red soil resource database. In this research, for the first time the soil type terrain method was adopted to express the spatial characteristics of the soil attribute, which greatly increased the matching accuracy.
