【摘要】 随着社会经济快速发展,城镇用地规模不断扩张,伴随着生态用地正逐渐消逝,土地生态问题也日益严峻。生态用地是国家或区域生态安全的保障,通过对区域生态用地进行合理规划布局,为区域可持续发展奠定基础。本文以柳州市为例,以其生态用地为研究对象,在分析其现状的基础上,合理规划布局柳州市生态用地,探寻符合柳州市的生态安全格局,达到柳州市社会、经济、生态可持续发展的目标。本文首先借鉴国内外对生态用地等相关方面的研究,界定本文研究中生态用地的概念,并基于全国土地利用分类体系对其进行分类,分为：自然生态用地、人工生态用地、潜在生态用地。其次从景观异质性、景观空间构型、景观单元特征三类景观指标体系中,选取9个景观指数,运用Fragstats3.3软件计算柳州市生态用地各景观指数,根据其计算结果分析柳州市生态用地景观空间格局,揭示了柳州市生态用地存在的问题。最后,在柳州市生态用地现状分析的基础上,依据景观综合水平对柳州市生态用地进行分级,再结合柳州市各县市生态服务价值及GDP进行生态服务价值/GDP分区。在两者空间叠加分析的基础上划分柳州市生态用地建设分区：中部缓坡平原建设区、南部岩溶盆地恢复区、北部山地丘陵建设区。根据生态用地建设分区的结果,提出“一心、两区、一廊道”柳州市生态用地规划布局模式,在遵循规划布局原则及此模式思维下对各区及柳江生态廊道提出其发展方向及目标,进行具体规划布局。并从法律制度、政策、资金技术投入、公众参与度等四个方面提出保障规划布局的对策。通过本文研究,建立以生态用地为基础的景观生态安全格局,为新一轮土地利用规划提供科学依据,具有重要的现实意义。更多还原

【Abstract】 With the development of social economy and continuous expansion of urban land as well as the ecological land gradually disappeared, the land ecological problem is increasingly serious. Ecological land is the guarantee for national and regional ecological security, so we should rationally plan and layout the regional ecological land to lay a foundation for regional sustainable development. In order to explore the ecological security pattern to accordance with Liuzhou city and achieve the social, economic and ecological sustainable development, this paper takes Liuzhou city for example, its ecological land as research object and based on current situation to reasonable plan and layout the ecological land of Liuzhou city.This paper defines the concept of ecological land at first through learning from the relative research about ecological land at home and abroad. Based on National Land Use Classification System, the ecological land is classified as natural ecological land, artificial ecological land and potential ecological land.Secondly, it choose nine landscape indices from three kinds of Landscape index system that are Landscape heterogeneity, landscape architecture, landscape unit features, and use Fragstats3.3 software to calculating the landscape index of ecological land for Liuzhou city. Then according to their calculation result, it analysis the landscape spatial pattern of ecological land and reveal the problems of ecological land in Liuzhou city.Finally, based on the analysis on present situation of ecological land and landscape comprehensive level in Liuzhou city, it grades the ecological land of Liuzhou city, then combines the ecological service value and its GDP ratio of each countries in Liuzhou city to grade the divided districts of ecological service value and its GDP. Based on two spatial overlay analysis it grades construction division of ecological land in Liuzhou city including construction zone in central gentle slope plain, restoration areas in southern Karst basin and construction zone in northern hilly. According to the result of ecological land construction divisions, author proposes the "one central, two districts, one corridor" mode for plan and layout the ecological land of Liuzhou city, proposes the development direction and goal as well as makes planning layout for ecological corridor of Liujiang town. It also proposes security planning and design strategies from the perspective of legal system, policies, capital and technology investment and the level of public participation.To construct landscape ecological security pattern based on ecological land can provide a scientific basis for a new round of land use planning and also has very important practical significance.更多还原
