基于敏感性和重要性的阜平县生态功能分区研究

Study of ecological function zoning in Fuping County based on sensitivity and importance

研究区选择太行山典型地段阜平县,依据生态环境现状,按照生态功能分区的原则和方法划分。对土地生态环境敏感性,生态功能重要性进行评价。在土地生态环境敏感性评价中,分布情况为由东南向西北逐渐敏感。生态功能重要性评价中重要性较低的地区受人类活动干扰较严重,重要性较高的地区位于银河自然保护区内以林地为主,森林覆盖率高,生态质量较高。基于地貌类型初步划分生态区为3个一级区;基于土地生态环境敏感性与生态功能重要性评价结果,采用二维关联判断矩阵在初步分区的结果上进一步将生态功能区划分为6个二级区;采用面积占优法确定主导因素,进一步将阜平县划分为13个三级区。

Fuping County,a typical part of Taihang Mountain,was selected as the study area.According to the current situation of ecological environment,it was divided according to the principle and method of ecological function zoning.The sensitivity of land ecological environment and the importance of ecological function were evaluated.The distribution pattern of land eco-environmental sensitivity assessment was gradually sensitive from southeast to northwest.In the evaluation of ecological function importance,the areas with low importance were more seriously disturbed by human activities,while the areas with high importance were mainly woodland in the Galactic Nature Reserve,with high forest coverage and high ecological quality.Based on geomorphic types,the ecological region was divided into three primary regions.Based on the evaluation results of land eco-environmental sensitivity and ecological function importance,the two-dimensional correlation judgment matrix was used to further divide the ecological function zoning into six secondary zones.The dominant factors were determined by the method of area dominance,and Fuping County was further divided into 13 three-level districts.
