公益林生态系统服务价值评价是公益林生态系统管理与可持续发展的重要内容,模型库及其管理系统是决策支持系统的核心。在公益林生态系统服务价值评价的主要内容与价值量评估公式、参数设置、计算方法与数据挖掘技术的基础上,使用SQLserver数据库技术通过模型字典设计公益林生态系统服务价值评价模型库,并按层次结构实现模型的分类入库存储;结合C#集成可视化开发工具实现模型目录树结构的模型库管理系统。系统层次清晰,易于模型添加、更新和删除,具有较强的计算、分析、预测与决策功能,辅助生态公益林管理与决策者提高决策水平和质量。
Evaluation of ecosystem service value of public welfare forest is an important part of ecosystem management and sustainable development of public welfare forest. Model library and its management system are the core of decision support system. Based on the assessment of the main content and value of ecological service value of public welfare forest ecosystem, parameter setting, calculation method and data mining technology, using SQLserver database technology to design ecosystem service valuation model library of public service forest through model dictionary, Structural realization of the model classification storage; combined with C # visualization development tools to achieve the model tree structure model database management system. The system has clear levels and is easy to add, update and delete models. It has strong calculation, analysis, prediction and decision-making functions, and helps the managers and decision-makers of ecological public welfare forests to improve their decision-making level and quality.
