为了科学评价煤矿废弃地植被恢复潜力，进而确定不同废弃地间植被恢复的优先顺序，根据土壤、地形、气候、废弃地现状各方面因素对植被恢复难易程度的影响，建立了各因素的隶属度函数；将三标度打分法与层次分析法相结合，确定了各因素的权重；采用模糊综合评价灰色关联优势分析的方法，建立了煤矿废弃地植被恢复潜力评价模型。对辽宁阜新市矿区煤矿废弃地植被恢复潜力进行了评价，评价结果与实际情况相符。该模型能够为确定矿区植被恢复的难易程度以及优先顺序提供决策支持。

以Intranet为核心技术，以Visual InterDev，Dhtml，M SDN，IESDK，Java Script，VB Script，SQL Server 710，Act ive Server Pages动态服务器网页，以及Photoshop 510图像处理等软件为开发工具。以Windows98为服务器客户应用软件平台，对河蟹的人工繁殖、蟹种培育、成蟹养殖、配饵投饲、蟹病防治等5个基本模块进行了系统集成，建立了一个网络化河蟹养殖专家系统。该系统属于管理及决策型专家系统，利用它可以对用户实现养殖预测、决策支持、信息咨询、技术推广等功能。

This paper presents a research attempt to develop and evaluate a Web-based tele-diagnosis system for fish diseases. Fish disease diagnosis is a complicated process and requires high level of expertise. A tele-diagnosis system T-VET is being developed and tested in China. T-VET is the key sub system of a Web-based expert system for fish disease diagnosis. This paper looks at why a tele-diagnosis system is needed and what are the advantages and difficulties in developing and using such a system. The system's architecture and components are described. Auser-centered approach was adopted throughout the development process to ensure the system would meet users' needs and will be accepted. As a result, the system functions were emerged and improved by users' requirements. The experience and feedback from testing and evaluating the system with potential users are discussed. Some valuable insights into the use of the Internet as a tele-diagnosis tool in aquaculture are highlighted.

文章针对定性推理/01算法存在组合爆问题，根据水产专家的多年总结的实践经验与知识，对鱼病的数据、信息进行了分析，将领域专家的知识作为约束条件，提出了基于层次因果的诊断模型的搜索策略，减少了推理分支，提高了效率。

在文献分析的基础上，针对已有研究粮食地区间贸易调控方法的不足，把管理思想、控制原理和自组织理论与软科学的多种方法有机地结合起来，研究出了粮食地区间贸易调控的系统分析方法。该方法主要包括类变量的选择及作用关系分析、反馈效应回路的构建及耦合和系统的演化与控制。
