The Short-Grass Steppe (SGS) was initiated as an LTER project in 1982 and has investigated the influences of climate, physiography, grazing, fire, and land-use on the structure, function, and dynamics of short-grass ecosystems. This research facilitates prediction of vulnerability of grassland ecosystems to on-going environmental change, through integration of experimental and observational studies to provide a mechanistic basis for forecasting the responses of semi-arid grasslands to changing conditions. This project contributes to understanding of the structure, function, and dynamics of the short-grass steppe ecoregion as it becomes ever more strongly influenced by changing land use and population. It assembles, integrates, and makes available valuable and unique long-term data sets on climate, biology, ecology, hydrology, biogeochemistry, physiography, and disturbances. The project has broad societal value through its contributions to improved management of semi-arid ecosystems. Its broader values also include extensive research-based training, educational program development, and public outreach programs.

短草草原（SGS）是1982年启动的LTER项目，主要研究气候、地形、放牧、火灾和土地利用对短草生态系统结构、功能和动态的影响。本研究通过实验与观测相结合的方法，为预测半干旱草原对环境变化的响应提供机理依据，促进草地生态系统对持续环境变化的脆弱性预测。该项目有助于了解短草草原生态区的结构、功能和动态，因为它受到土地利用和人口变化的强烈影响。它收集、整合并提供有关气候、生物学、生态学、水文学、生物地球化学、地理和扰动的有价值和独特的长期数据集。该项目有助于改善半干旱生态系统的管理，具有广泛的社会价值。其更广泛的价值还包括广泛的以研究为基础的培训、教育计划的发展和公共宣传计划。
