On the base of applied tech. and system structure, the key tech. are expressed in detail. It includes:Knowledge representation technology: it is described in two stages by "Depictive frame + Rule group"."Depictive frame" is used to reflect the factors concerning question field."Rule group" reflects the son-question in question field; knowledge management system: it is made up of knowledge-base editing component, factor classifying component, knowledge inspecting component and extractive knowledge component; uncertainty reasoning adopt method of elicitation search strategy and data drive controlled by member knowledge. It take reliability of compound proof at first. That can resolve the matching contradiction. Reasoning explanation introduce pre-text and followed method of resolving path. Knowledge discovery component take SLIQ as basic arithmetic. It provides classification model in two stage forms which aim at training suit. That is decision tree and productive rule.

在确定应用技术与系统结构的基础上，重点阐述了本文的核心技术，这包括：知识表示技术，采用"描述框架+规则组"的层次结构，"描述框架"用于描述问题域所涉及的因素，"规则组"反映问题域内的子问题；知识管理系统，由知识库编辑构件、因素分类构件、知识检测构件和知识求精构件组成；不确定性推理机采用启发式搜索策略，元知识控制的数据驱动，以复合证据可信度优先作为匹配冲突消解的策略，推理解释采用预置文本与求解路径追踪的方法；知识发现，采用SLIQ快速可伸缩算法，分类模型用判定树与产生式规则两种形式描述。

Then the informationtheoretic entropy measure and Laplace error rate evaluation functions are applied to the path search in extension matrix, and a heuristic algorithm ECA based on entropy is given The time complexity of ECA is also analyzed Finally, ECA is applied to several real-world domains such as sleep examples and handwritten digit recognition, and the experimental results show that ECA can produce more simple and efficient rules.

针对实际应用领域中的噪音问题，从统计学的角度，对扩张矩阵理论的定义加以扩充，放宽关于规则的概念描述限制：在训练例子集上归纳得到的概念，不一定完全正确分类训练例子集，而是以较大的正确概率分类训练集，并对新的例子有较好的预测能力。

Finally, PNV had been mapped according to Boolean discrete methods to connect climate submodel and vegetation submodel by GIS. PNV map first represented the spatial distribution of all vegetation types of 4 physiognomic levels in Taiwan, also integrated the diverse comments of altitudinal vegetation zones and geographical climatic regions in the past. Besides, the scattered ranges of 36 dominant trees in the moisture-thermal regime and climatic zone had been drawn via coordinating 585 plot-data with MWI and WDI.

为达绘制潜在植群图之最终目标，本研究以MWI及WDI之网格图层代表气候亚模型，以潜在植群形相分类方案之各阶类型代表植群亚模型，藉由布林分离法联系此2亚模型之关系，建构气候–植群分类模型，并以地理资讯系统绘制出包含群系纲、群系亚纲、群系组、群系之潜在植群图，首次完整呈现台湾各阶植群类型之空间分布，合理说明了山地植群带分化、北部植群下降及西南部冬季乾旱等现象，亦整合过去各种有关垂直性山地植群带状分化与水平性地理气候区划分的复杂意见；另外，本研究将585个样区林木座标标定於MWI及WDI，绘制36种林木於水热境制及热量气候带之分布范围。
