摘要
就目前而言，我国植保机械格局仍以手动和小型机动为主,防治功效低下。大部分农药喷撒仍以动力机喷撒为主,依靠喷嘴喷出时的动能和空气载运再加上重力喷洒到靶标植物上,并附着在其表面。通过这种方式散布的农药仅有少部分附着在植物表面上,绝大部分流失到土壤和环境中。这不仅浪费巨大，而且将产生生态平衡破坏、农林产品农药残留超标、害虫再猖獗、害虫抗药性增加、新害虫不断出现、人畜农药中毒等一系列问题。而在国外，许多国家的农业已经全面进入电子信息时代，通过包括人工智能技术在内的各种高新技术的综合集成应用，大幅促进了农业生产和管理的科学化和现代化。而智能决策支持系统的建设将是保证农业产业化经营，提高我国农业国际竞争力的必然途径。
本文论述了系统的开发背景和设计目标，并对系统开发所采用的技术进行了相应的介绍。在系统开发过程中，对系统进行需求分析，按系统的功能进行模块划分。再对系统进行可行性分析，确定在目前的条件下，开发农药喷施智能决策支持系统是可行的。接着对系统中所需的数据库以及决策系统进行建立与设计。本文系统介绍现今农药喷施决策系统的需求、系统分析及设计方案，最终并给出农药喷施智能决策支持系统的过程。

Abstract
For now, the pattern of plant protection machinery is still mainly manual and small motorized, prevention and treatment efficacy is low. Most of the power machines spraying pesticide still mainly rely on the kinetic energy of the nozzle and the air carrier plus gravity sprayed onto the target plants and attached to the surface. In this way only a small portion of spreading pesticide attached to the surface of the plant, most of the pesticide loss to the soil and the environment. This is not only huge waste, and will destroy ecological balance, agricultural and forestry products excessive pesticide residues, pest resurgence, pest resistance increases, new emerging pests, drinking pesticide poisoning and other issues. In foreign countries, many countries’ agriculture has full access to the electronic information age, by a variety of high-tech including artificial intelligence techniques to comprehensive integrated applications, significantly promote the scientific and modern of agricultural production and agricultural management. Constructing the intelligent decision support system will be to ensure industrialized operation of agriculture, improve the international competitiveness of our country's agricultural inevitable way.
This issue discusses the background and design goals of the system development, and system development technology used for the corresponding description. In the system development processing, Doing needs analysis for the system, according to the system's function dividing module. Then doing feasibility analysis for the system to determine developing pesticide spraying intelligent decision support system is feasible in the current conditions. Then establish and design the system needed databases and decision-making systems. This issue describes pesticide spraying decision system requirements in now, system analysis and design, and gives the ultimate of intelligent pesticide spraying process decision support system.
Key word: intelligent Pesticide spraying Database Design Decision Support System
