Despite the importance of land legacy effects on land use/land cover change (LULCC), historical data remain underutilized in analyses of social–environmental systems (SES). Drought, a slow-onset disaster, serves as an ideal case study to examine how multitemporal LULCC provides context for contemporary land use patterns. We use historical geographic information systems (HGIS) to analyze land ownership change, resource access, and land use in Cimarron County, Oklahoma, the epicenter of the Dust Bowl. We digitize archival county plats covering 1931 through 2014 into an HGIS. Through analysis of ownership information, we trace changes in familial and corporate landholdings during this period, exploring how different landowner types have changed over time. Aerial photography analysis helps to quantify the adoption of irrigation in relation to family survivability. Results show that families with larger landholdings in the 1930s were significantly more likely to persist through the Dust Bowl and continue owning land in the present. Access to the Ogallala Aquifer also increased the duration of land ownership. Corporate operators were most aggressive in adopting irrigation. Results raise questions of sustainability and uneven access to resources. We argue that land legacy has profound impacts nearly a century later. Further, SES studies can benefit from incorporating HGIS into their repertoire.

尽管土地遗产对土地利用/土地覆盖变化 (LULCC) 的影响很重要，但历史数据在社会环境系统 (SES) 分析中仍未得到充分利用。干旱是一种缓慢发生的灾害，是研究多时 LULCC 如何为当代土地利用模式提供背景的理想案例研究。我们使用历史地理信息系统 (HGIS) 来分析沙尘暴中心俄克拉荷马州西马伦县的土地所有权变化、资源获取和土地使用。我们将 1931 年至 2014 年的档案县平台数字化为 HGIS。通过对所有权信息的分析，我们追踪了这一时期家庭和公司土地持有量的变化，探索不同的土地所有者类型如何随时间变化。航拍分析有助于量化灌溉的采用与家庭生存能力的关系。结果表明，在 1930 年代拥有更多土地的家庭更有可能在沙尘暴中坚持下来并在现在继续拥有土地。进入奥加拉拉含水层也增加了土地所有权的持续时间。企业经营者在采用灌溉方面最为积极。结果提出了可持续性和资源获取不均的问题。我们认为，土地遗产在近一个世纪后产生了深远的影响。此外，SES 研究可以从将 HGIS 纳入其曲目中受益。进入奥加拉拉含水层也增加了土地所有权的持续时间。企业经营者在采用灌溉方面最为积极。结果提出了可持续性和资源获取不均的问题。我们认为，土地遗产在近一个世纪后产生了深远的影响。此外，SES 研究可以从将 HGIS 纳入其曲目中受益。进入奥加拉拉含水层也增加了土地所有权的持续时间。企业经营者在采用灌溉方面最为积极。结果提出了可持续性和资源获取不均的问题。我们认为，土地遗产在近一个世纪后产生了深远的影响。此外，SES 研究可以从将 HGIS 纳入其曲目中受益。
