中文摘要：

为了促进农业科技成果交易，加快农业科技成果转化，将WebGIS技术与综合模糊评价模型相结合，设计并开发了基于WebGIS的农业科技成果价值评估系统。系统实现了农业科技成果时空数据的存储与管理、农业科技成果价值评估、价值评估结果时空特征分析以及结果的可视化，为农业科技成果管理部门提供了一个集数据管理与时空分析为一体的工具。研究构建了价值评估三级指标体系，综合考虑技术、效益和市场三方面因素对农业科技成果进行综合价值评估，能够为农业科技成果的转化交易提供参考。

英文摘要：

In order to promote the trading and accelerate the transformation of agricultural scientific and technological achievements （ASTA） , a WebGIS-based system for evaluating the value of ASTA was designed and developed. Object-oriented JAVA language was adopted to realize various functions of the system. The functions included the storage and management of spatial and temporal data, value evaluation of ASTA, spatial and temporal characteristics analysis of value evaluation results and visualization of the results. As an integrative tool for managing data and analyzing spatial and temporal characteristics, the system provided service for agricultural scientific and technological achievements management department. Comprehensive fuzzy method was adopted to evaluate the value of ASTA. In order to ensure the accuracy of evaluation results, the indexes were extracted from many influence factors and then the evaluation index system was constructed. The index system took into account all the influence of technology, market and benefit. So far, totally 265 ASTA were evaluated in the system, which were produced in 2010--2015. To validate the correctness of the system, an experiment was carried out, and results showed that the accuracy of the system was good. The application of the system showed that it provided an efficient-fast third-party assessment tool for ASTA holders, and it also supplied an intelligent management tool for ASTA management department. Furthermore, evaluation results of the system can provide reference for ASTA trading.
