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

This shapefile contains landscape factors representing human disturbances summarized to local and network catchments of river reaches for the state of Vermont. 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 Vermont. 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（shapefile）包含针对美国佛蒙特州河段的局地集水区与网络集水区汇总得到的、表征人为干扰的景观因子。
本数据集通过将要素类"关联至NHDPLUSV1.gdb的美国本土2010年国家鱼类栖息地行动计划（National Fish Habitat Action Plan, NFHAP）人类干扰数据与栖息地条件指数（Habitat Condition Index, HCI）得分"裁剪至佛蒙特州州界而得到。
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。
用于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) 可有效用于鱼类栖息地评估；(2) 在整个研究区域内的汇编方式保持一致；(3) 能够反映过去10年的环境状况；(4) 空间分辨率足够高，可实现局地集水区单元间的有效对比。
本数据集通过COMID标识符，将上述变量与国家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，同时也可通过该标识符与NHDPlusV1的河段建立关联。
集水区属性分为两类：局地集水区（指直接向某一河段汇水的陆地区域，属性字段以"L_"为前缀）与网络集水区（指所有上游汇入该河段出口的集水区，包含该河段自身的局地集水区，属性字段以"N_"为前缀）。
本形状文件还包含基于生物指标对全生态区人为景观干扰的响应性所生成的栖息地条件指数得分。
针对局地集水区干扰、网络集水区干扰分别生成了独立得分，同时还生成了累积得分：该累积得分取对特定生物指标产生最强限制作用的局地或网络集水区干扰因子所对应的得分。
本次评估仅对溪流与江河河段进行了得分赋值（详细流程请参见对应章节）。
