京津冀地区国家公园规划的生态敏感性评价

Ecological Sensitivity in National Park Planning in the Beijing-Tianjin-Hebei Region

京津冀地区自然生态类型丰富多样,自然地理地貌差别巨大,生态服务功能分异明显,在该区域建设国家公园有重要意义。如何选择适宜区域进行国家公园建设,是现阶段的国家公园规划难点问题。采用土地利用现状、海拔、坡度、到自然保护区的距离、到湿地的距离、到城镇的距离、到铁路的距离、到公路的距离等指标因子,进行京津冀地区生态敏感性评价。结果表明:京津冀地区生态高度敏感区域和极度敏感区域主要集中在北部燕山和西部太行山山地区域,平原区在环渤海湾的沿海湿地呈现中-高度敏感性。

The Beijing-Tianjin-Hebei region is rich in natural ecosystems. There are huge differences in natural geography,physiognomy and ecosystem services. It is of great significance to build national parks in this area. How to choose the appropriate area for national park construction is difficult. In this study,we choose six factors to evaluate the ecological sensitivity of the Beijing-Tianjin-Hebei region,such as land use type,altitude,slope,distance to natural reserve,distance to wetland,distance to town,distance to railway and distance to highway. The results showed that the highly sensitive areas in the Beijing-Tianjin-Hebei region were mainly concentrated in the northern Yanshan Mountain and western Taihang Mountain areas. The coastal wetlands in the Bohai Bay also presented high sensitivity. The research provides an important scientific basis for the location choosing of national parks in the Beijing-Tianjin-Hebei region.
