摘要
在工作站（ＳｕｎＳＰＡＲＣｓｔａｔｉｏｎⅡ）与微机的联网平台上，用地理信息系统软件ＡＲＣ／ＩＮＦＯ对西湖流域的非点源污染研究做了有益的探索，初步建立了西湖流域非点源污染信息数据库．讨论了专题数据的分类编码，空间数据的数字化、编辑、坐标转换等，并生成了西湖流域的数字地面模型（ＤＥＭ），也为西湖流域非点源污染的深入研究提供了基础数据平台．
The database of nonpoint source pollution in West Lake watershed based on the network platform of Sun SPARC station Ⅱand personal computer in this study was established. Using GIS software (ARC/INFO), the research included: abstracting special factor from spatial data, coding attribute data, digitizing, editing, coordinate transferring and generating the digital elevation model (DEM). The work also provides a fundamental data supply for the further research of nonpoint source pollution in West Lake watershed.
