ABSTRACT 97-26862 Hopkinson W/WS: Integrated, ecological-economic modeling of watersheds and estuaries at multiple scales The objective of this research is to integrate socioeconomic models with spatially explicit models of land use, ecosystem biogeochemistry and watershed hydrology to provide comprehensive assessments of human activities on nutrient, sediment and water fluxes for the Ipswich watershed in coastal Massachusetts. An additional objective is to develop approaches that will allow application of these models to other watersheds. To assess human impacts on watershed dynamics, the investigators will use four types of models: socioeconomic, land-use change, hydrologic and stream biogeochemical. A key goal is to develop a means of assessing the impacts of urbanization and land-use change on watersheds and estuarine ecosystems in general, not just a specific assessment for the Ipswich River. The approach will enable the researchers to better assess human impacts on watersheds and to evaluate management strategies for minimizing or reversing watershed, riverine and estuarine degradation.

摘要97-26862 HOPKINSON W/WS：在多个尺度上的分水岭和河口的综合，生态经济建模，这项研究的目的是将社会经济模型与土地使用的空间使用模型相结合，生态系统生物地球化学和水域的全面评估，并为人类的水域提供全面的评估。马萨诸塞州沿海地区。 另一个目标是开发将这些模型应用于其他流域的方法。为了评估人类对流域动态的影响，研究人员将使用四种类型的模型：社会经济，土地利用变化，水文和溪流生物地球化学。一个关键目标是开发一种评估城市化和土地利用变化对流域和河口生态系统的影响的方法，而不仅仅是对伊普斯维奇河的特定评估。该方法将使研究人员能够更好地评估人类对流域的影响，并评估管理策略，以最大程度地减少或逆转分水岭，河流和河口降解。
