From basic theory and the concept of ecological restoration. focusing on the ecological restoration of the ecosystem restoration projects in the regulation. and a detailed briefing on the construction of three models, different features for the design and optimization of air regulation could provide a reference model. Key words : Loess Plateau, ecosystem restoration, spatial analysis一、选题目的和意义陕北黄土高原位于陕西北部, 是中国黄土高原的主体部分, 它介于北纬34°48′ ~39° 35′ 和东经 107° 28′ ~111° 15′ 之间 . 总面积 8.06 ×104km2, 约占陕西省总面积的39.05%,行政上包括延安市和榆林市. 该地区是我国水土流失最为严重、社会经济发展落后的贫困地区之一, 生态环境问题较为突出. 黄河中的泥沙每年有 8 亿吨来自陕北地区 , 占三门峡以上河段输沙量的一半, 因此 , 陕北黄土高原生态环境的有效治理是陕北地区乃至整个黄河流域急待解决的问题.个人资料整理仅限学习使用<一)自然地理状况陕北黄土高原以土壤侵蚀作用强烈、水土流失严重而著称. 其特殊的地质、地貌和气候条件形成了独特的自然地...
