资源简介：

This dataset depicts the extent and frequency of dry land in the Atchafalaya Basin Floodway System (ABFS). The analysis used 28 Landsat images (1984-2008) classified into categories of wet and dry. Each pixel value represents the number times each pixel was classified as dry land in that stack of 28 images. Methodologies for this classification are available in Allen et al. (2008) and Allen (2016). The Atchafalaya Basin is a resource that must be managed on a system-wide basis to ensure this invaluable national resource is protected and restored. It is recognized that better tools must be developed for managing the Basin and that data evaluation is necessary to ensure sound decision-making. The natural resource inventory and assessment system (NRIAS) that was approved and funded in the FY 2010 Louisiana Department of Natural Resources Atchafalaya Basin Program Annual Plan and served as the primary tool for decision making in the Basin. The system provided a means for scientists to access relevant project data for the Basin and to request and fund data acquisition, monitoring, and data analysis to be used in project planning. This will be critical in providing information necessary for the development and approval of specific projects to be included for construction in future Annual Plans, projects that meet the needs of Louisiana citizens and protect our our natural resources. This and related datasets were created to demonstrate the patterns of inundation, turbid water and floating aquatic vegetation in the Atchafalaya Basin Floodway System at various river levels of the Atchafalaya River.Allen, Y.C., Constant, G.C., and Couvillion, B.R., 2008, Preliminary classification of water areas within the Atchafalaya Basin Floodway System by using Landsat imagery: U.S. Geological Survey Open-File Report 2008 1320, 14 p. https://pubs.er.usgs.gov/usgspubs/ofr/ofr20081320Allen, Y.C.

本数据集刻画了阿查法拉亚盆地泄洪道系统（Atchafalaya Basin Floodway System，ABFS）内旱地的分布范围与发生频次。本次分析采用了1984年至2008年间的28景陆地卫星（Landsat）影像，并将其划分为水体与旱地两类。每个像素的数值代表该像素在这28景影像组合中被归类为旱地的次数。本次分类的方法可参阅Allen等人（2008）以及Allen（2016）的相关研究。阿查法拉亚盆地是一项需以系统全域视角开展管理的宝贵自然资源，需通过全域化管理保障这一国家级珍贵资源得到保护与修复。学界公认，需开发更完善的盆地管理工具，且开展数据评估是保障科学决策的必要前提。自然资源清查与评估系统（Natural Resource Inventory and Assessment System，NRIAS）已在2010财年路易斯安那州自然资源部阿查法拉亚盆地项目年度计划中获批并获得拨款，成为该盆地决策制定的核心工具。该系统为科研人员提供了获取该盆地相关项目数据的渠道，并支持科研人员申请数据采集、监测与数据分析相关经费，以用于项目规划工作。这对于为未来年度计划中拟纳入施工的特定项目的开发与审批提供必要信息至关重要——此类项目需契合路易斯安那州民众的需求，并保护当地自然资源。本数据集及相关数据集旨在展现阿查法拉亚河不同水位条件下，阿查法拉亚盆地泄洪道系统内的淹没态势、浑水分布与漂浮水生植被格局。 Allen, Y.C.、Constant, G.C. 与 Couvillion, B.R.，2008年，《利用陆地卫星（Landsat）影像对阿查法拉亚盆地泄洪道系统内水域进行初步分类》：美国地质调查局公开文件报告2008-1320，共14页。https://pubs.er.usgs.gov/usgspubs/ofr/ofr20081320 Allen, Y.C.（2016）. 《利用陆地卫星（Landsat）影像开展泛滥平原淹没频次的景观尺度评估》. 《河流研究与应用》（River Research and Applications），第32卷，DOI: 10.1002/rra.2987。
