放牧牲畜对水质的影响，特别是对侵蚀和沉积的影响，是美国西南部的一个重要问题。为了响应联邦和州的法规，牧场管理的最佳管理实践（BMPs）正在许多西部州开发和实施，尽管许多实践的有效性和经济影响尚未得到检验。为了评估bmp的潜在有效性，设计了一个空间决策支持系统（SDSS），将水质、牲畜管理和经济问题结合起来。SDSS是通过将水文、侵蚀、牲畜管理和经济模拟模型与地理信息系统和数据库管理系统相结合而开发的。SDSS可以帮助管理人员根据站点特定的数据选择bmp的类型和位置，并通过Internet部署，提供通过web浏览器访问的方式。SDSS为土地管理者提供了一种方法，以确定导致水质退化的关键地区，并设计和实施流域管理措施，以改善水质。海报将介绍SDSS，并提供应用的个案研究例子。
The impact of livestock grazing on water quality, especially erosion and sedimentation, is an important concern in the southwestern United States. In response to Federal and State regulations, Best Management Practices (BMPs) for rangeland management are being developed and implemented in many western states, although the efficacy and economic impact of many practices have not been examined. To assess the potential effectiveness of BMPs, a Spatial Decision Support System (SDSS) has been designed to integrate water quality, livestock management and economic concerns. The SDSS was developed through the integration of hydrologic, erosion, livestock management and economic simulation models linked with a geographic information system and database management system. The SDSS can help managers select the type and location of BMPs based on sitespecific data and is deployed via the Internet providing access through a web browser. The SDSS provides land managers with a means to identify critical areas causing water quality degradation and design and implement watershed management practices to improve water quality. The poster will describe the SDSS and provide case study examples of its application.
