摘要
以昭通市为例,探讨生态屏障地区的功能区划方案。生态屏障地区是国家“十一五”规划提出的4大类功能区中的限制开发区或禁止开发区,其目标是实施以国家、区域或流域生态安全为保障的生态系统恢复和保护工程。运用功能区划的基本思想,以昭通市自然、生态与社会经济主要因子的评价为基础,借助G IS分析工具,以参评因子的空间态势为依据,划分生态保护和经济发展功能兼备的主体功能区,为在中小尺度的生态保护地区划分功能区提供了研究案例。
Ecological shelter zone reconstruction is a restoring and protecting ecosystem project aimed to the ecological safety of nations, regions and basins. At the end of the last century, Reconstruction of eco-sheher zone of the upper reaches of the Yangtze River became one of the most important objects, it includes： the restoration of vegetation, the protection of habitat, the construction of biodiversity, the prevention of soil erosion and a series projects of renovating and protecting ecology. Eco-sheher zone, which is a refined or forbidden region, just is one of four kinds of functional regions in ＂eleventh five-years of national project＂. The article takes Zhaotong for example, tries the functional regionalization of eco-sheher zone to supply research cases for low and medium scale ecological protective regions to divide functional regions. With the guidance of ＂eleventh five-years of national project＂, based on Zhaotong city＇s natural, ecological, social-economic and other main factors, applying the theories of regionalization, authors set down the principle of converse evaluation which is based on town-unit. This would be useful to mountainous areas＇regional function division. Authors select 1：50000 relief maps, recently RS data, LUCC data and town-unit social-economic statistical data, by GIS methods, analyze spatial status of above factors, draw functional-regions map of ecological protection and economy development in Zhaotong. Zhaotong Prefecture is divided into two-level functional-regions, the first-level zone include three regions, which work as regions to lead developing direction, and supply suggestions to sub-regions＂ development and construction; the second-level zone include eight sub-regions, which are policy implemented regions, and supply suggestions to Zhaotong Prefecture＇s eco-shelter zone reconstructions. As the conclusion, the authors take three first-regions as analytical frames, and establish detailed plan of functional regions, including 8 sub-regions to implement eco-shelter zone reconstructions.
