簡介：摘要人居環(huán)境作為自然、經(jīng)濟、社會的綜合系統(tǒng)，是人類生存、生產(chǎn)和進行各種社會活動的主要場所。鄉(xiāng)村人居環(huán)境作為人居環(huán)境的組成部分，對于整個區(qū)域環(huán)境的可持續(xù)發(fā)展具有非常重要的作劇。伴隨著城鄉(xiāng)差距曰益拉人，“城鄉(xiāng)統(tǒng)籌”和“社會主義新農(nóng)村建設(shè)”重大戰(zhàn)略決策的實施，對鄉(xiāng)村人居環(huán)境評價與優(yōu)化研究具有重要的理論和現(xiàn)實意義。寧夏移民T程實施以來，已建立多處不同規(guī)模、不同類型的移民鄉(xiāng)村，取得了顯著的經(jīng)濟效益、社會效益以及生態(tài)效益。寧夏紅寺堡生態(tài)移民區(qū)作為全國最人的生態(tài)移民安置區(qū)，地處寧夏中部干旱帶的生態(tài)脆弱區(qū)，以本區(qū)為研究樣區(qū)對寧夏移民鄉(xiāng)村人居環(huán)境質(zhì)量進行評價與優(yōu)化，對于寧夏移民鄉(xiāng)村的建設(shè)與區(qū)域經(jīng)濟的可持續(xù)發(fā)展具有重要的理論和現(xiàn)實意義。本文通過對寧夏紅寺堡移民鄉(xiāng)村的實地調(diào)查，明確目前紅寺堡移民鄉(xiāng)村人居環(huán)境建沒現(xiàn)狀及存在的問題，并且參照村鎮(zhèn)規(guī)劃和農(nóng)村小康社會建設(shè)的標準對紅寺堡移氏鄉(xiāng)村人居環(huán)境的客觀建設(shè)水平進行評價，分析總結(jié)紅寺堡移民鄉(xiāng)村人居環(huán)境質(zhì)量與農(nóng)村小康社會建設(shè)標準之間存在的差距，明確其客觀建設(shè)水平。此外，通過問卷及訪談的形式調(diào)查了紅寺堡移民對現(xiàn)有人居環(huán)境的滿意度程度，將滿意度分為非常滿意、滿意、一般、不滿意、非常不滿意五個等級。在此基礎(chǔ)上運用模糊綜合評價方法對紅寺堡移民鄉(xiāng)村人居環(huán)境各大系統(tǒng)的滿意度進行主觀測評。評價結(jié)果表明1紅寺堡移民鄉(xiāng)村人居環(huán)境的客觀建設(shè)水平總體上與農(nóng)村小康社會建設(shè)的目標值相比較還存在一定的差距居住條件、社會經(jīng)濟、基礎(chǔ)設(shè)施、公共服務(wù)設(shè)施四人系統(tǒng)內(nèi)部的少數(shù)指標的現(xiàn)狀值低于目標值，有待于進一步完善；生態(tài)環(huán)境和鄉(xiāng)風(fēng)文明兩大系統(tǒng)的客觀建設(shè)水平遠低于農(nóng)村小康社會建設(shè)的標準值，需加大建設(shè)力度。2紅寺堡移民區(qū)居民對現(xiàn)有生活環(huán)境的滿意度總體評價為一般，對各大系統(tǒng)的滿意度與其客觀建設(shè)水平呈正相關(guān)。移民對目前的居住條件非常滿意，對本村基礎(chǔ)設(shè)施雨I公共服務(wù)設(shè)施建設(shè)以及鄉(xiāng)風(fēng)文明三方面的評價為一般，對生態(tài)環(huán)境表示非常不滿意。因此，寧夏移民鄉(xiāng)村的建設(shè)優(yōu)化應(yīng)結(jié)合移民鄉(xiāng)村的發(fā)展現(xiàn)狀和發(fā)展前景，從移民不滿意的環(huán)節(jié)入手，綜合考慮區(qū)域經(jīng)濟可持續(xù)發(fā)展的基礎(chǔ)上制定相應(yīng)的優(yōu)化措施，促進寧夏移民鄉(xiāng)村的可持續(xù)發(fā)展。關(guān)鍵詞評價與優(yōu)化，鄉(xiāng)村人居環(huán)境，移民，紅寺堡區(qū)，寧夏
