摘　　要：京津冀一体化,协同发展已上升为国家战略,着力扩大环境容量生态空间,加强生态环境保护合作是京津冀协同发展的具体要求,而促进该区域自然植被的保护和自然保护区布局的优化是生态环境保护的重要组成。文章以京津冀地区的自然保护区基础信息、植被类型信息以及地形地貌信息为基础数据,分析了京津冀地区自然保护区的基本特征,利用GIS的叠加分析功能,研究了京津冀地区的植被保护现状与保护空缺,分析了自然保护区分布与海拔梯度的关系,植被分布与海拔梯度的关系。结果表明:京津冀地区的自然保护区以森林类型为主,其次是内陆湿地类型;京津冀地区的主要森林植被类型得到了较好的保护,草原草甸植被的保护需要加强;自然保护区的分布和植被类型的分布在海拔梯度上具有较高的一致性,在海拔800—1200 m内分布的自然保护区数量最多,也是森林植被类型数量与分布面积最多的海拔段。因此,加强河北省西北部的草原草甸生态系统自然保护区的建设,有助于弥补京津冀地区自然植被保护的不足;加强河北省涞源县-阜平县,井陉县-赞皇县等西部太行山海拔800—1200 m范围内自然保护区的建设,有助于保护暖温带落叶阔叶林生态系统,构建由太行山和燕山森林类型自然保护区组成的生态屏障。The integration and the collaborative development of Beijing-Tianjin-Hebei Region(BTHR)are proposed as anational strategy.It is the specific requirement to expand the environmental capacity of ecological space,and strengthen thecooperation of the ecological environment protection in the development of BTHR.The protection of natural vegetation andoptimization of the pattern of natural reserves are important contents of ecological environment protection.Based on the data ofnature reserves,vegetation types and topography information of BTHR,the basic characteristics of nature reserves in BTHR areanalyzed.By using overlaying analysis function of GIS,the present situation and the gap of vegetation protection in BTHR arediscussed,the relationship between the distribution of nature reserves and altitudinal gradient is analyzed,and the distribution ofvegetation and altitudinal gradient is analyzed.The results showed that the nature reserves belonging to forest type are the majortype in the BTHR,followed by the inland wetlands types.The main forest vegetation types are protected in the region.Theprotection of the meadow steppe needs to be strengthen.The distribution of nature reserves and the vegetation types have ahigher consistency on the altitudinal gradient.Most of nature reserves distribute at altitude of800-1200m.The numbers ofnature reserves belong to the forest vegetation types and their areas are the most too.Therefore,to strengthen the construction ofnature reserves belonging to the meadow steppe ecosystem in northwest of Hebei Province is helpful for compensating for the lack of protection on natural vegetation types.To strengthen the construction of nature reserve between altitude of800-1200meters on Taihang Mountain in the western of Hebei Province,such as Laiyuan–Fuping counties,Jingxing-Zanhuang counties,are helpful for protecting the warm temperate deciduous broad-leaved forest ecosystems,and for forming ecological shelterzone which is composed by forest type nature reserve on Taihang Mountain and Yansha
