沿海地区是世界上城市化速度最快的地区之一。城市化对水文、地貌和生态的诸多影响使得城市湿地的功能不同于非城市湿地。此外，城市地区的湿地可能具有非城市地区所缺乏的与人类有关的价值，因为它们提供了一些与自然的接触，以及一些在城市景观中罕见的娱乐机会。评估城市地区修复工作的成功与否，首先需要确定城市对遗址影响的种类和强度，其次需要评估功能性能。在两个评估级别上制定成功标准取决于对参考领域（成功标准将适用的一组湿地）的适当定义，以及对该领域内一组参考地点的记录；两者都必须基于适合感兴趣地区的城市背景。本文以新泽西州的城市湿地研究为例，介绍了建立参考域、参考湿地集和评估城市影响标准的程序。(C) 2000 Elsevier Science B.V.版权所有
Coastal regions are among the most rapidly urbanizing places on earth. The numerous effects of urbanization on hydrology, geomorphology, and ecology make wetlands in urban regions function differently from wetlands in non-urban lands. Furthermore, wetlands ill urban regions may take on human-related values that they lack in non-urban areas, as they provide some contact with nature, and some opportunities for recreations that an otherwise rare in the urban landscape. Evaluations of the success of restorations in urban regions require criteria first to determine the kinds, and intensities of urban influence on the site, and secondly to assess functional performance. The development of success criteria, at both the levels of assessment, depends on the proper definition of a reference domain (the set of wetlands to which success criteria will apply), and the documentation of a set of reference sites within the domain; both must be based within the urban context appropriate for the region of interest. An example is presented from a study of urban wetlands in New Jersey of a procedure for establishing the reference domain, the reference set of wetlands, and criteria for the assessment of urban influence.
