National Fish Habitat Action Plan (NFHAP) 2010 HCI Scores and Human Disturbance Data (linked to NHDPLUSV1) for Washington

This shapefile contains landscape factors representing human disturbances summarized to local and network catchments of river reaches for the state of Washington. This dataset is the result of clipping the feature class 'NFHAP 2010 HCI Scores and Human Disturbance Data for the Conterminous United States linked to NHDPLUSV1.gdb' to the state boundary of Washington. Landscape factors include land uses, population density, roads, dams, mines, and point-source pollution sites. The source datasets that were compiled and attributed to catchments were identified as being: (1) meaningful for assessing fish habitat; (2) consistent across the entire study area in the way that they were assembled; (3) representative of conditions in the past 10 years, and (4) of sufficient spatial resolution that they could be used to make valid comparisons among local catchment units. In this data set, these variables are linked to the catchments of the National Hydrography Dataset Plus Version 1 (NHDPlusV1) using the COMID identifier. They can also be linked to the reaches of the NHDPlusV1 using the COMID identifier. Catchment attributes are available for both local catchments (defined as the land area draining directly to a reach; attributes begin with "L_" prefix) and network catchments (defined by all upstream contributing catchments to the reach's outlet, including the reach's own local catchment; attributes begin with "N_" prefix). This shapefile also includes habitat condition scores created based on responsiveness of biological metrics to anthropogenic landscape disturbances throughout ecoregions. Separate scores were created by considering disturbances within local catchments, network catchments, and a cumulative score that accounted for the most limiting disturbance operating on a given biological metric in either local or network catchments. This assessment only scored reaches representing streams and rivers (see the process section for more details). Please use the following citation: Esselman, P., D.M. Infante, L. Wang, W. Taylor, W.

本形状文件包含针对华盛顿州河段的本地集水区与网络集水区所汇总得到的、表征人为干扰的景观因子。本数据集是将要素类“NFHAP 2010年人类干扰指数得分与美国本土人为干扰数据（关联至NHDPlusV1地理数据库）”裁剪至华盛顿州州界后得到的成果。景观因子涵盖土地利用类型、人口密度、道路、水坝、矿山以及点源污染点位。经汇编并赋予集水区属性的源数据集需满足以下判定标准：（1）可有效评估鱼类栖息地；（2）在整个研究区内的组装方式保持一致；（3）能够反映过去十年的环境状况；（4）具备足够的空间分辨率，可用于本地集水区单元间的有效对比。本数据集中，上述变量通过COMID标识符与全国水文数据集增强版第1版（National Hydrography Dataset Plus Version 1，NHDPlusV1）的集水区进行关联。这些变量同样可通过COMID标识符与NHDPlusV1的河段进行关联。集水区属性可分为两类：本地集水区（定义为直接向河段汇水的陆地区域，属性以“L_”为前缀）与网络集水区（定义为所有汇入该河段出水口的上游汇水集水区，包含河段自身的本地集水区，属性以“N_”为前缀）。本形状文件还包含基于生物指标对各生态区内人为景观干扰的响应性所构建的栖息地状况得分。针对本地集水区、网络集水区内的干扰分别构建了专属得分，同时还构建了累积得分，该累积得分会考量在本地或网络集水区中对特定生物指标产生最大限制作用的干扰因素。本评估仅对代表溪流与河流的河段进行得分赋值（详细信息请参阅流程章节）。请使用以下引用格式：埃塞尔曼（Esselman, P.）、英凡特（Infante, D.M.）、王（Wang, L.）、泰勒（Taylor, W.）、丹尼尔（Daniel, W.）、廷利（Tingley, R.）、芬纳（Fenner, J.）、库珀（Cooper, A.）、维费里希（Wieferich, D.）、索恩布鲁（Thornbrugh, D.）与罗斯（Ross, J.）（2011年4月）：《华盛顿州2010年国家鱼类栖息地行动计划（NFHAP）人类干扰指数得分与关联NHDPlusV1的人为干扰数据》，国家鱼类栖息地伙伴关系数据系统，http://dx.doi.org/doi:10.5066/F77S7KSQ
