【摘要】 采用SQL Sever2005管理空间和属性数据,以Visual C#和Arc Engine为开发平台,构建洪湖湿地需水量分析信息系统.根据洪湖地区地形和地理数据,采用格网法计算洪湖湿地静库容;针对洪湖湿地地理位置和功能,构建洪湖湿地需水量模型;根据研究区多年水文气象数据,对洪湖湿地水量平衡状况进行计算、分析和预测.运用GIS技术,本系统实现了洪湖湿地需水量的定性和定量分析,为洪湖湿地保护与生态恢复提供信息服务和管理决策支持.更多还原

【Abstract】 Employing SQL Sever2005 to manage spatial and attribute data and using Visual C # and ArcGIS Engine as development platform,this paper developed an analysis information system for the water requirement of Honghu Wetland.According to the terrain and geographic data of Honghu Lake area,the static capacity of Honghu Wetland was calculated by using grid method.Based on the location and functions of Honghu Wetland,the computational model for the water requirement of Honghu Wetland was built.Using the hydro-meteorological data of the study area for many years,the water balance of Honghu Wetland was calculated,analyzed and forecasted.With the help of GIS technology,the analysis information system meets the need of making both qualitative and quantitative analysis on the water requirement of Honghu Wetland and could provide powerful support of information services and management decision for the conservation and ecological restoration of Honghu Wetland.更多还原
