【摘要】 生态敏感因子和生态敏感区是区域生态环境的决定性因子和关键区域。该文从大气、生境(生物生存环境)、水、土地、地质五个角度选取生态敏感因子,划分生态敏感区,建立了一个较为完善的划分生态敏感区的指标体系。以北部湾(广西)经济区为例,划分了该区域的五种子敏感区和综合生态敏感区。在理论上,提出了一种较为模式化的生态敏感区划分方法,并探讨了城镇群等较大区域的生态敏感区划分;在技术上,根据生态要素的空间连续性特征,充分利用GIS作为表达和分析手段;在实践上,对北部湾经济区的生态问题做出了一定研究,为该区域的城镇群规划提供了生态参考。更多还原

【Abstract】 Ecological Sensitive Factors (ESF) and Ecological Sensitive Area (ESA) are significant to regional ecology. They are the important bases in regional planning and mass cities planning. This paper divides Ecological Sensitive Area into five types,from the vision of atmosphere,water,propagation,land,geology,and constructs an indicator system for Ecological Sensitive Area Division. Case study in Beibu Gulf (Guangxi) Economic Zone shows the division method used in mass cities area,which provides a standard method for Ecological Sensitive Area Division. The result of the case study analyzes some ecology problems in this area and provides ecology reference for later mass cities planning.更多还原
