摘　　要：布设国土生态屏障是国土资源部提出的最新的土地利用规划理念。以重庆市永川区为例,选取自然、生态和社会经济等因子建立评价指标体系,借助GIS分析工具,将其划分为5个限制级,并对该区建设生态屏障的基础条件进行评价。结果表明:限制性高值区集中在五条低山,低山之间的限制程度降低。整体看来,西北地区限制性高,向东南逐渐降低。构建了永川区生态屏障网络体系:主体由东北-西南走向的数列山地与山间、丘间的密集水网构成。南端则以长江干流为依托,构成水体生态屏障。最后以参评因子的空间态势为依据,将永川划分为2级6个功能区,并对各功能区生态屏障建设提出具体布设方案,为中小尺度地区土地利用规划中生态屏障的建设提供了研究案例。Ecological shelter zone is the latest concept of land-use planning put forward by Homeland Ministry of Land and Resources.It takes Yongchuan as an example,which selects natural,ecological and socio-economic factors as the establishment of evaluation index system,uses GIS analysis tools,to divide Yongchuan into five restrict levels and build an ecological shelter zone of the basic conditions for the evaluation.The results show that： the restrictive high-value concentrates in five areas of low mountains,it lowers among each.All in all,the northwest area is restrictive with the high-value,which gradually reduces to the southeast.To build a network of ecological shelter zone in Yongchuan,the main body is constructed by the intensive water network from the northeast-southwest towards the mountains and hills series.Yangtze River as the south is based on building ecological shelter zone.Finally,it divides Yongchuan into 2 levels,6 functional areas by the spatial situations of evaluated factors and puts forward the detail plan for construction of each functional areas in ecological shelter zone,then provides a case study to construct ecological shelter zone of land use planning for small-medium scale areas.
