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

This shapefile contains landscape factors representing human disturbances summarized to local and network catchments of river reaches for the state of New Mexico. 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 New Mexico. 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）包含表征人类扰动的景观因子，这些因子已汇总至新墨西哥州河段的本地汇水区与网络汇水区。本数据集系将要素类“关联NHDPLUSV1.gdb的美国本土全国鱼类栖息地行动计划（National Fish Habitat Action Plan，NFHAP）2010年栖息地条件指数（Habitat Condition Index，HCI）得分与人类扰动数据”裁剪至新墨西哥州州界后所得。景观因子涵盖土地利用类型、人口密度、道路、水坝、矿山与点源污染场地。经汇总并赋值至汇水区的源数据集满足以下遴选标准：(1) 可有效支撑鱼类栖息地评估；(2) 在整个研究区内的构建方式保持统一；(3) 能够反映近10年的环境现状；(4) 具备足够的空间分辨率，可在本地汇水单元间开展可靠的横向对比。本数据集通过COMID标识符，将上述变量关联至全国水文数据集增强版第1版（National Hydrography Dataset Plus Version 1，NHDPlusV1）的汇水区，同时也可通过该标识符与NHDPlusV1的河段建立关联。汇水区属性同时覆盖两类汇水区：本地汇水区指直接向河段汇水的陆地区域，其属性以“L_”为前缀；网络汇水区指所有向该河段出口汇水的上游汇水区（含河段自身的本地汇水区），其属性以“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扰动的响应性所构建的栖息地条件得分。研究分别构建了基于本地汇水区扰动、网络汇水区扰动的得分，以及累积得分：累积得分考量了对某一生物指标产生最强限制作用的本地或网络汇水区扰动因子。本次评估仅对溪流与河流类河段进行了得分赋值（详细流程参见文档流程章节）。引用格式如下：Esselman P., Infante D.M., Wang L., Taylor W., Daniel W., Tingley R., Fenner J., Cooper A., Wieferich D., Thornbrugh D. 及 Ross J.
