Konza Prairie site, station Lyon County, KS (FIPS 20111), study of human population (total) in units of number on a yearly timescale

The EcoTrends project was established in 2004 by Dr. Debra Peters
(Jornada Basin LTER, USDA-ARS Jornada Experimental Range) and
Dr. Ariel Lugo (Luquillo LTER, USDA-FS Luquillo Experimental Forest)
to support the collection and analysis of long-term ecological datasets.
The project is a large synthesis effort focused on improving the accessibility
and use of long-term data. At present, there are ~50 state and federally funded
research sites that are participating and contributing to the EcoTrends project,
including all 26 Long-Term Ecological Research (LTER) sites and sites funded by
the USDA Agriculture Research Service (ARS), USDA Forest Service,
US Department of Energy, US Geological Survey (USGS) and numerous universities. Data from the EcoTrends project are available through an exploratory web portal
(http://www.ecotrends.info). This web portal enables the continuation of data
compilation and accessibility by users through an interactive web application.
Ongoing data compilation is updated through both manual and automatic
processing as part of the LTER Provenance Aware Synthesis Tracking
Architecture (PASTA). The web portal is a collaboration between the Jornada LTER
and the LTER Network Office. The following dataset from Konza Prairie (KNZ)
contains human population (total) measurements in number units
and were aggregated to a yearly timescale.

EcoTrends项目由黛布拉·彼得斯博士（霍纳达盆地长期生态研究（Long-Term Ecological Research, LTER）、美国农业部农业研究局（USDA-ARS）霍纳达实验牧场）与阿里尔·卢戈博士（卢奎洛长期生态研究（Long-Term Ecological Research, LTER）、美国农业部林务局（USDA-FS）卢奎洛实验林）于2004年创立，旨在支撑长期生态数据集的采集与分析工作。该项目为大型综合研究计划，核心聚焦于提升长期数据的可获取性与利用率。目前共有约50个州立及联邦资助的研究站点参与EcoTrends项目并贡献数据，其中涵盖全部26个长期生态研究（Long-Term Ecological Research, LTER）站点，以及由美国农业部农业研究局（ARS）、美国农业部林务局、美国能源部、美国地质调查局（USGS）及众多高校资助的站点。EcoTrends项目的数据可通过探索性网络门户（http://www.ecotrends.info）获取。该网络门户依托交互式Web应用，支持用户持续开展数据汇编与数据获取工作。作为长期生态研究（Long-Term Ecological Research, LTER）溯源感知综合跟踪架构（PASTA）的组成部分，持续推进的数据汇编工作通过人工与自动两种处理方式进行更新。本网络门户由霍纳达LTER与LTER网络办公室合作开发。下述来自康扎草原（KNZ）的数据集包含以数量为单位的总人口统计值，并已聚合至年度时间尺度。
