【摘要】：水文變化的生態(tài)限度框架(ELOHA)是環(huán)境流理論最新成果。ELOHA要求對河流按照水文情勢特征進行分類,相同類型河流的水文—生態(tài)關系具有相似性。ELOHA還要求對開發(fā)前后水文情勢變化進行分析,計算現(xiàn)狀水文條件與基準水文條件的偏離程度。ELOHA提出了水文情勢變化預期生態(tài)響應的若干假定,總結了一套為建立水文—生態(tài)關系采用的生態(tài)指標。在建立大型水文和生物數(shù)據(jù)庫的基礎上,運用統(tǒng)計學方法擬合水文—生態(tài)函數(shù)關系。最后,各利益相關者對水文變化引起的生態(tài)風險進行評估,認定可以接受的生態(tài)風險水平,再依據(jù)水文—生態(tài)曲線,確定環(huán)境流標準。
[Abstract]:The ecological limit framework of hydrological change (ELOHA) is the latest achievement of environmental flow theory. ELOHA requires rivers to be classified according to hydrological characteristics. The hydrological and ecological relationships of the same type of rivers are similar. ELOHA also requires analysis of changes in hydrological conditions before and after development. ELOHA put forward some assumptions of expected ecological response of hydrological situation change and summarized a set of ecological indexes for establishing hydrology ecological relationship. Based on the establishment of large hydrological and biological databases, the hydrological and ecological functions were fitted by statistical method. Finally, the stakeholders assess the ecological risk caused by the hydrological change, determine the acceptable level of ecological risk, and then determine the standard of environmental flow according to the hydrology-ecological curve.
