Salinization Model with links to source files

This computational model of irrigation agriculture is used to study the effects of salinization in Mesopotamia. Scholars have long suspected that central and southern Mesopotamia present environments which limited agricultural production over long-term periods. In regions such as central Mesopotamia, where salinization likely affected settlement in different periods but was more manageable than in more southern regions, fallowing regimes, natural and engineered leaching, and decisions made on when to crop were strategies applied in order to limit the effects of salinization. The model is used to assess the effectiveness of these coping strategies by incorporating projected climate, soil, and landscape conditions with agricultural practices. The simulation results not only demonstrate the effectiveness and limitations of techniques to inhibiting progressive salinization but can be compared with the archaeological record in order to determine if the results correspond to past events and help to interpret past settlement history.本灌溉农业计算模型旨在研究美索不达米亚地区的盐碱化影响。长期以来，学界普遍推测美索不达米亚中部与南部的环境会在长期尺度上制约农业生产。在美索不达米亚中部这类区域，盐碱化可能在不同时期对当地聚落造成影响，但相较于更南部的区域，其危害更易管控。彼时先民采用休耕制度、自然淋洗与工程化淋洗，以及择机播种等策略，以缓解盐碱化的不利影响。该模型通过整合预测的气候、土壤与景观条件及农业生产实践，用以评估上述应对策略的有效性。模拟结果不仅阐明了抑制渐进式盐碱化的各类技术的有效性与局限性，还可与考古记录进行比对，以验证模拟结果是否与历史史实相符，并助力解读古代聚落的发展历程。
