摘要
在探讨和分析菜子湖湿地生态数据的多源异构、时空相关和水位动态特性的基础上,提出一种基于“图层对象状态”的三域时空数据模型,并采用ArcGIS平台构建了菜子湖湿地生态数据库管理系统。该系统具有图库管理、查询操作和制图综合等功能,能够直观地呈现菜子湖湿地生境、越冬期水鸟种群数量和分布格局、栖息地选择对水位变化的响应关系,可为菜子湖不同适应性水位优化调度提供科学依据。
Based on discussion and analysis of the multi-source heterogeneity,spatio-temporal correlation and water level dynamic characteristics of Caizi Lake wetland ecological data,a three-domain spatio-temporal data model on the basis of“Layer-Object-State”was proposed,and the ArcGIS platform was adopted to construct the Caizi Lake wetland ecological database management system.This system has the function of library management,query operation,cartographic generalization and so on.It can intuitively present the response relationship of the wetland habitat,the population number and distribution pattern of overwintering water birds and the habitat selection to water level changes,which provides scientific basis for the optimal operation of different adaptive water levels in Caizi Lake.
