2、脆弱性評價結(jié)果顯示,寧夏限制開發(fā)生態(tài)區(qū)生態(tài)脆弱性可分為極度脆弱、高度脆弱、中度脆弱、低度脆弱共4個等級,其中,極度脆弱區(qū)面積達(dá)到研究區(qū)總面積的51.76%,高度脆弱區(qū)占21.15%,中度脆弱區(qū)占15.56%,低度脆弱區(qū)占11.52%。針對研究區(qū)生態(tài)脆弱性狀態(tài)提出了5種區(qū)域發(fā)展模式(即以生態(tài)補(bǔ)償為主體的發(fā)展模式;以生態(tài)移民為主體的發(fā)展模式,基礎(chǔ)設(shè)施建設(shè)推動型發(fā)展模式,以生態(tài)草畜業(yè)為主體的發(fā)展模式和現(xiàn)代農(nóng)業(yè)發(fā)展模式。關(guān)鍵詞:限制開發(fā)區(qū);生態(tài)脆弱性;發(fā)展模式;寧夏回族自治區(qū)文獻(xiàn)標(biāo)識碼:A文章編號:1000-288X(2014)04-0236-07中圖分類號:K901,X171.1DOI:1
