农业科技示范户申报系统的设计与实现
摘 要
科学技术是第一生产力。农户作为我国农业生产经营的基本单位,承担着接
受和使用农业科技的任务。在农村选择培育一批科技示范户,进行重点扶持,以
示范户带动广大农户,是科技与生产结合的有效形式。农业科技示范户由农户自
主申报,经村、乡镇、县市等各级行政管理部门组织评审确定,然后由各级农业
科技推广部门进行技术推广。本项工作中的评审、审批、示范户管理等基本都是
有人工操作,存在工作效率低下、评审缺乏系统化的评价标准和透明性、推广工
作缺乏信息化管理手段、专家与农户沟通不通畅等问题。通过构建一个基于 Web
的申报系统,可以有效解决上述问题。
文中提出了示范户五维评价模型和示范能力成熟度模型。多个专家从多个维
度对申报者进行评价,使得评审的过程更加客观、公平。成熟度模型的建立,能
公正地确定申报户的成熟等级,给行政审批决策提供了支持,并牵引农户向更好
的方向发展。本文在对农民科技示范户申报、评审、农技推广工作充分调研的基
础上,采用面向对象的技术对软件系统进行了分析、设计,使用.NET 和三层架
构技术实现了该系统并进行了测试。系统主要功能包括示范户申报、专家评审、
行政审批、农技推广活动管理、农技问题与解答、农技资讯等。
系统在功能上能满足申报、评价、审批、示范户信息管理等工作需要,将来
可以在数据统计、报表等方面进一步丰富功能。

Design and Implementation of Agricultural Technology
Demonstration Households Reporting System
Abstract
The science technology is the primary productive forces. The farmers as the
basic unit of agricultural production have the responsible for using of agricultural
science and the acceptance. By developing a number of scientific and technological
demonstration households in rural and provide major supports in order that led the
most of farmers which is an effective way of technology combination and production.
The agricultural science and technology demonstration households can be
self-reported by farmers. After accreditation from each level of government, the
technology will be promoted by agricultural science and technology departments from
all levels. Basically review session and approval flow in this working activity as well
as management of demonstration households are manual operation and will be
impacted the inefficiency and the assessment is lack of systematic evaluation criteria
and transparency, the promotion of the lack of information management, the problem
of communication between experts and farmers, etc. By building a Web-based
reporting system, problems can be resolved effectively.
This thesis proposes a demonstration households evaluation of the
five-dimensional model and a demonstration households Maturity Model. Multiple
experts from multiple dimensions to evaluate the reporting, making the review
process more objective and fair. Maturity model will fairly determine the maturity
level of reporting households, provide the support to the administrative examination
and approval decisions, and lead farmers for the better direction. In this thesis, on the
basis of investigation of reporting, evaluation and agricultural extension with farmers
and technology demonstration households, to adopt object-oriented technology
software system to analysis and design and also at the meantime, to use NET
three-tier technology to achieve this system and did the testing. The main features of
III
the system include the demonstration households reporting, expert review,
administrative examination and approval, the management of agricultural extension
activities, agricultural questions and answers, agricultural information, etc.
The functions of the system could be met the needs of reporting, evaluation,
approval, and demonstration households information management function. The data
statistics, statements and other functions can be improved in the future study.
Key words: Agricultural science and technology; Demonstration households;
Reporting; Evaluation model; Three-tier architecture
