摘要随着地理信息系统的迅速发展,使其对制图综合的要求越来越高,制图综合成为评价地理信息系统性能的一个重要标准。制图综合系统不仅仅要面对海量的时空GIS数据，还需要专业的绘图知识和经验，这是一个集成系统和一般的制图GIS软件的区别，即包含了许多关键的GIS集成系统图形和专业知识的优劣决定着系统的质量，是在地图上表示系统的全面的知识和其正式符号绘制法进行组织，还取决于合理使用计算机、数据库结构的知识。湿地是人类最重要的一个景观生态的居住环境,是自然界中生物多样性和地球上最重要的生态系统之一。因此需要重要保护湿地的健康状况。植被覆盖率作为一个重要的生态参数和量化指标来衡量植被覆盖率和增长,它准确地获得湿地的植物蒸腾和土壤水分生态环境中扮演重要角色的水土保持研究湿地蒸发。因此,湿地植被覆盖率估算植被及相关研究具有重要意义。62379
Abstract With the development of geographic information systems, and its comprehensive cartographic requirements increasingly high cartographic generalization become evaluate geographic information system performance merits an important indicator. Cartographic generalization system not only have to face a large number of space-time GIS data, but also need the knowledge and experience of experts in drawing, which is an integrated system and general cartographic GIS software distinction, a key GIS integrated system that contains many graphics and expert knowledge the quality of the pros and cons, depending on the map represents a comprehensive knowledge of the system and the organization of its formal symbol drawing law carried out, and also depends on the rational use of computers, knowledge of the database structure. Wetlands are one of mankind's most important landscape ecological living environment and the natural world richest biopersity on the planet is one of the most important ecosystems. Thereby protecting the health of the wetland is particularly important. Vegetation coverage as an important ecological parameters and quantitative indicators to measure the vegetation cover and growth, which accurately obtain soil and water conservation plant transpiration and soil moisture wetland ecological environment detection wetlands evaporation play an important role. Thus, the vegetation coverage estimate wetland vegetation research and related areas of great significance.
