摘要
本文阐述了生态水文专题图集的前期数据准备、图集制作规范、图集制作流程等内容,并以ArcGIS10.0为平台,选择辽河流域和太湖流域作为研究对象,通过模版化制图技术,将流域的环境要素数字化;然后结合研究区的调查监测数据、水生态功能分区,制作了流域生态水文专题图集。该图集作为国家重大水专项"十一五"研究成果的一部分,具有内容丰富、表现直观、易于修改等优点,是一部水生态系统驱动机制研究和分区技术研究的图集。
The data preparation, mapping specification and procedure for ecohydrologic atlas were presented in this paper. The Liao River and Taihu Basins were selected as the study area, and the ecohydrologic atlas was drawn at the ArcGIS 10.0 platform. Envi- ronmental factors in two river basins were digitized through data preparation and pretreatment. The eco-hydrologic atlas was drawn with the template-drawing skill on the basis of monitoring data and functional zoning of ecohydrology in the study area. The atlas, an impor- tant result during the ＂Eleventh Five-year＂ period, was easily to be modified and integrated more information for the ecologic system and environment in the study area. The eco-hydrologic atlas could provide guidance for the study on the driving mechanism and zoning technology of aquatic ecosystems.
