赣江上游土地覆被变化的水文响应研究
Hydrologic Responses of Land Cover Change in Upper Reaches of Ganjiang River
【摘要】 针对土地利用/覆被变化对流域水文循环产生重要影响的问题,以赣江上游峡山水文站以上集水区域为例,基于1978~1987年相关资料,采用极端土地覆被法构建4种未来土地覆被情景,运用陆面水文模型Noah-LSM模拟各土地覆被情景下流域水文要素(蒸散发、径流)的变化情势。
【Abstract】 Aiming at the problem of the significant impacts of land use/cover change on watershed hydrologic cycle,the upper catchment area controlled by Xiashan hydrologic station in the upper reaches of Ganjiang River is selected as the study area.Based on the data from 1978 to 1987,four future land cover scenarios are established with the extreme land cover scenario construction method.Then the Noah Land Surface Model(Noah LSM) is adopted to simulate the possible variation trends of hydrological variables(evaportranspiration/runoff) under each land cover scenario.
