Hydrologic Impacts of Forest Disturbance, Conversion and Restoration

A global database comparing the impacts of disturbance, conversion, and restoration of native forests on hydrological processes of great importance for water security. The database is focused on local comparisons or a limited number of hydrological processes and land-use types, spanning 1049 cases from 287 primary studies in 58 countries and 12 biomes. The database includes changes in six hydrological processes (i.e. interception, overland flow, evapotranspiration -total and as a share of rainfall, infiltration, and streamflow, and land-use types (logged, degraded, burned, clear-cut, and restored native forests, monoculture tree plantations, orchards/agroforestry areas, pasturelands, and croplands). Even this database is not focused on evaluating water balances or considers water closure regimes, values on these processes can be used as indicators of changes in water processes across native forest cover and other land use types.本全球数据库旨在对比原生林受干扰、转化及恢复活动对水文过程的影响，相关研究对水安全保障具有重要价值。该数据库虽以局部对比、有限水文过程与土地利用类型为研究重点，但涵盖了来自58个国家、12个生物群区的287项原始研究的1049个案例。本数据库包含6类水文过程的变化数据，即截留、地表径流、总蒸散发及其占降雨量比例、入渗与河川径流；同时覆盖10类土地利用类型，包括采伐林、退化林、火烧迹地、皆伐原生林、恢复原生林、单一树种人工林、果园/农林业用地、牧草地与农田。尽管本数据库未聚焦于水量平衡评估或水文闭合状态分析，但其收录的上述水文过程数值仍可作为原生林覆盖与其他土地利用类型间水文过程变化的指示指标。
