摘要
利用提取式数据库管理技术建立了兴林灭螺复合生态模式基本因子数据库，实现对各种数据的快速查询、筛选、排序等操作，在建立多种数学模型进行数据处理的基础上，用Ｖｉｓｕａｌ Ｂａｓｉｃ 函数实现了动态数据链接，通过ＤＤＥ 技术实现了数据、信息和图象的转换．运用面向对象的知识表示法建立了系统的知识类层次，完善了相应的推理机制．通过对拟开发滩地相关因子的量化处理，完成滩地的立地类型划分和立地质量评价， 推荐优化生态模式、技术措施等，提出经济、生态、社会三方面的效益分析．并设计了多种满足ＧＵＩ 标准的交互式人机界面．
With the technique of pick up database management, the database of basic factors in the “planting trees and killing oncomelania” system is constructed, by which, all data can be searched, filtered and sorted conveniently. Based on the constructed mathematical models, the dynamic data linking is realized by some Visual Basic functions. Moreover, the connection of data, information and graphics is realized by dynamic data exchange. By the expression of object oriented knowledge, the systemic knowledge class hierarchy is set up, and the corresponding reasoning mechanism is improved. According to the result of mathematical processing of factors relative to intended beach development, site classification and site quality evaluation are completed, and the optimized ecological patterns and technological measures are recommended. The economic, ecological and social effects can be analyzed and evaluated. Some commutative user machine interfaces satisfied GUI standards are also designed.
