【摘要】 水稻生态平衡施肥决策支持系统是以生态平衡施肥模型为理论基础，以实用和高新技术优化组装的技术体系为实现手段，以生态型肥料为载体的新的计算机施肥体系。生态平衡施肥模型是建立在质量守恒定律和有效养分转化关系的基础上，生态型肥料是同时满足高产、低投、没有污染等多目标的最佳肥料投入组合。技术体系包括：肥料改性、根域或肥域土壤条件改善、减少养分投入、养分再利用和循环技术、生态平衡施肥特征参数试验方法、专用肥配方试验方法、土壤有效养分速测方法、施肥预测系统和管理系统等。水稻生态平衡施肥决策支持系统开发是利用专家的专业知识和信息技术，就黑龙江省某一区域以往施肥技术研究成果进行的科学总结和高度集成，并通过计算机这一媒体表达出来，也即相当于把一定区域的施肥技术按一定的规则组织起来后放入电脑中，建立一个辅助人们进行决策支持的一个系统，这一系统具有因地制宜、技术优化集成、使用简捷等特点，因此，具有广泛推广应用前景。水稻生态平衡施肥决策支持系统的设计遵循软件工程的生命周期法，分阶段设计开发，用结构化分析方法提出整个系统概要设计方案。在决策支持系统的设计与实现中，首先分析现行水稻生态平衡施肥的流程之后，绘制了决策支持系统的数据流图，然后采用数据流分析法，提出子系统的功能结构表，最后利用VB6.0、ACCESS2000数据库、多媒体技术等面向对象的编程工具，实现水稻生态平衡施肥决策支持系统的功能。根据需要设计出5个模块，考虑到运筹学研究的特点，不是对每一个决策模块孤立进行评价，而是把它同系统内所有其它模块相互作用结合起来做出评价，把相互影响的各模块作为一个统一体，从总体利益的观点出发，寻找出一个优化协调的生态平衡施肥方案。系统主要功能包括学习功能、施肥量预测功能、输入输出功能、统计功能、财务结算功能和数据更新功能等。该系统将计算机技术和农学知识有机结合，技术先进、功能全面、结构规范、界面友好、易学实用。对黑龙江省智能化农业信息技术的发展具有一定的理论和实用价值。更多还原

【Abstract】 The decision support system for rice ecological balanced fertilization is based on the theory of ecological balanced Model, Using the technical system of the utility and new advanced technology, achieving the new compute-fertilization-system about the ecological balanced fertilizer. The model of rice ecological balanced fertilization is based on the conservation of mass and the relation of transmuting of the availability nutrition, the balanced fertilization is the best combination of fertilizer input which can meet the needs of high quantity, low investment, none-pollution, and so on. The technology system includes: changing the qualities of fertilization; improving the soil condition of root region, and fertilize region, reducing the input of the fertilization, reuse the nutrient and cycle technology; the way of testing the ecological balanced fertilization, the way of testing the special fertilization formula; the way of fast testing the effective nutrient, forecast system of the fertilization, management system, and so on.Using the expert’s professional knowledge and the information technology develops the design for the system of rice ecological balanced fertilization. Summarize the fertilizing investigation result scientifically and highly integrating at one of the region in Heilongjiang province. And expressed by compute, namely, organizing the regional fertilizer technology according to a certainty rule then put it into compute, thereby building up a decision support system that can assistant people to work, this system has sever virtues, such as, it can adjust measures to local conditions, technology optimization and integration, applying conveniently, and so on. Hereby, it has an abroad extending and applying future.The design of the decision support system for rice ecological balanced fertilization keeps to the life-period method of the software engineering, be designed phases, The summary design project of the whole system was brought forward by using the configurable analyses method, during decision support system design and realization, first analyze the flow of rice ecological balanced fertilization, and plot the database stream chart of rice ecological balanced fertilization, then adopt the data stream analysis method to bring forward sub-system function configuration table. At last, using OO(object oriented) program tool like the VB6.0, ACCESS2000, MULTIMEDIA, etc. To realize the function of ecological balanced fertilization system. So that I design five modules, considering the characteristic of operational research, not to estimate every module isolated, but integrate to estimate all modules that the system includes take the reciprocal modules as a whole, take into account the collectivity benefit to seek the optimization project.The system mainly include the learning function, the fertilization quantity forecasting function, input and output function, Stat function, financing balanced function, data update function. The system integrates the compute with the agronomy. It has the characteristic ofhigh technology, comprehensive function, configuration criterion, interface friendly, easily studying and utility. It has great value in theory and utility for the development of the intellectualize agriculture information technology of the Heilongjiang province.Candidate: Zhou BaopingSpeciality.
