【摘要】：從"狀態(tài)-壓力-響應(yīng)"指標(biāo)系統(tǒng)框架出發(fā),建立了鄱陽(yáng)湖流域水資源安全評(píng)價(jià)指標(biāo)體系。采用綜合指數(shù)法,構(gòu)建變異系數(shù)對(duì)指標(biāo)權(quán)重進(jìn)行客觀賦值,對(duì)鄱陽(yáng)湖水資源安全進(jìn)行評(píng)價(jià)。結(jié)果表明:河網(wǎng)密度和農(nóng)業(yè)生產(chǎn)化肥農(nóng)藥施用量等指標(biāo)對(duì)鄱陽(yáng)湖水資源安全有較大影響。在2000~2010年鄱陽(yáng)湖流域水資源安全經(jīng)歷了由一般狀態(tài)(狀態(tài)Ⅲ)到良好狀態(tài)(狀態(tài)Ⅳ),再到一般狀態(tài)(狀態(tài)Ⅲ),最后發(fā)展為較差狀態(tài)(狀態(tài)Ⅱ)的過(guò)程。從警源上分析發(fā)現(xiàn),這種變化主要由區(qū)域經(jīng)濟(jì)不斷增長(zhǎng),人口壓力增大,工農(nóng)業(yè)生產(chǎn)生活用水增加,化肥農(nóng)藥施用量增加所致。從總體趨勢(shì)上看,鄱陽(yáng)湖流域水資源安全狀態(tài)呈現(xiàn)惡化的趨勢(shì),雖然近年環(huán)保意識(shí)逐漸增強(qiáng),在環(huán)保投資方面有所增加,并且提高了污水處理率,加強(qiáng)了工業(yè)廢水排放管理,但還是難以承受經(jīng)濟(jì)社會(huì)發(fā)展的壓力,使得水資源安全暴露出逐漸惡化的趨勢(shì),最后定量地分析了水資源安全狀態(tài)變化原因,并針對(duì)水資源保護(hù)提出了具體保護(hù)措施,給出經(jīng)濟(jì)發(fā)展的用水約束條件以保障鄱陽(yáng)湖流域水資源安全。對(duì)水資源安全做出合理定量的評(píng)價(jià),可為鄱陽(yáng)湖流域水資源合理開(kāi)發(fā)和可持續(xù)利用提供科學(xué)依據(jù)。
[Abstract]:Based on the frame of "state-pressure-response" index system, the evaluation index system of water resources security in Poyang Lake basin is established. Based on the comprehensive index method, the coefficient of variation was constructed to evaluate the water resources safety of Poyang Lake. The results showed that the density of river network and the amount of chemical fertilizer and pesticide applied in agricultural production had great influence on the water resources safety of Poyang Lake. From 2000 to 2010, the water resources security in Poyang Lake basin experienced a process from general state (state 鈪，
