| 英文简介 | Ecological water requirement is one of the hot issues of eco-hydrology study both at home and abroad, and is fundamental scientific problem for ecol-environmental rehabilitation and protection in region. Based on theory and method of ecological water requirement at home and abroad, applied statistical analyses method, spatial analyses method and remote sensing and GIS method, ecological water requirement type were researched, and characteristic and law of ecological water requirement were analyzed, which spatial-temporal variation characteristic and distribution rule of ecological water requirement were revealed and different protection aim of ecological water requirement configuration law and regulation scheme of ecological water were put forward in the middle reaches oasis of Shule river basin. The suitable calculation methods of ecological water requirement were discussed, ecological water requirement were quantitatively evaluated in the middle reaches oasis of Shule river basin. The quantitative model of ecological water requirement were built and based on ecological process, characteristic of ecological water requirement were simulated in different ecological type in the middle reaches oasis of Shule river basin. The ecological water requirement threshold were studied, and threshold model of ecological water requirement were established in the middle reaches oasis of Shule river basin and based on ecological process, the action mechanism, configuration model and spatial distribution pattern of water resource were clarified, which would develop hydrology theory in arid area river basin and offered theoretically basis for with reason collocation and optimal use of water resource in arid area. |
