【摘要】 在数字湖泊系统建设中存在着大量的综合应用和决策分析问题,而空间分析模型和算法是开展上述工作的基础.本文首先分析了数字湖泊地理空间分析的特性和基本方法,研究了紧耦合和松耦合两种建模方式;然后对湖泊区域数字地形的多尺度表达问题进行了研究,最后提出了湖泊区域不同尺度空间数据的组织方式和数据库建立的方法与技术路线.更多还原

【Abstract】 Many problems concerning the specialized and decision-making models exist in the lake digitalizing management information system,of which the spatial analysis models and algorithms are the foundation.The characteristics and the principles of the digitalizing lake geospatial analysis are outlined first.Then the tight and loose coupling models between the specialized and geospatial data are issued.Furthermore,the demonstrations of the digital topography of the lake watershed in multiple scales are discussed.Finally,the methods of the data organization and the database generation of the multiple scale geospatial data for the lake watershed are expressed.更多还原
