【摘要】：為了有效保護(hù)和管理干旱區(qū)內(nèi)陸河流,以葉爾羌河卡群—艾力克塔木河段為研究對象,提出"以可達(dá)最佳狀態(tài)為標(biāo)準(zhǔn)"的河流健康評價(jià)標(biāo)準(zhǔn);基于壓力-狀態(tài)-響應(yīng)模型建立了包含24項(xiàng)指標(biāo)的河流健康評價(jià)指標(biāo)體系;構(gòu)建了基于突變級數(shù)法的河流健康評價(jià)模型,進(jìn)行河流健康評價(jià)研究。結(jié)果表明:評價(jià)現(xiàn)狀年2015年該河段目標(biāo)層突變級數(shù)為0.95,河流健康綜合評價(jià)等級為Ⅲ級,處于亞健康狀態(tài),即河流健康為由健康向不健康過渡的預(yù)警狀態(tài)。評價(jià)結(jié)果與實(shí)際情況基本符合,河流健康生命已受到威脅,河流健康維護(hù)工作勢在必行,維護(hù)河流健康的關(guān)鍵是滿足河道生態(tài)基流保障率,提高河道外用水尤其是農(nóng)田灌溉用水效率,以及提高流域管理機(jī)構(gòu)河流綜合治理水平和水資源優(yōu)化配置效率。
[Abstract]:In order to effectively protect and manage inland rivers in arid area, the river health evaluation standard based on the best condition of the river is put forward, which is based on the Kalquan-Alektamu reach of the Yerqiang River as the research object. Based on the pressure-state-response model, a river health evaluation index system with 24 indexes was established, and a river health evaluation model based on the catastrophe series method was constructed to study the river health evaluation. The results show that in 2015, the level of target level mutation is 0.95, and the comprehensive evaluation grade of river health is grade 鈪，
