摘要
人类活动是当前自然保护区保护与管理面临的主要威胁因素之一。针对不同人类活动的土地利用类型特点进行分类,利用地理信息系统和遥感技术,提取2010年度407个国家级自然保护区人类活动土地利用斑块,进而分析和统计国家级自然保护区内人类活动的分布现状,最终为管理部门管理和控制区内人类活动提供依据。结果表明,405个国家级自然保护区存在人类活动,人类活动斑块土地总面积为242.43万hm^2,占国家级自然保护区总面积的2.58%;人类活动主要分布在实验区内,实验区内人类活动斑块土地总面积为143.06万hm^2,占人类活动斑块土地总面积的59%;涉及保护区数量最多的人类活动斑块土地利用类型为农业生产用地,有360个自然保护区内有农业生产用地,农业生产用地总面积为211.03万hm^2。
Human activity is one of the main threats to the protection and management of nature reserves. According to characteristics of each type of human activity and land use, classification was done, and patches of human activity and land use in the 407 national nature reserves in 2010 were extracted with the aid of GIS and RS technology, for further anal-ysis and statistics of status of the distribution of human activities in the national nature reserves, of which the results would, as expected, provide some basic information for administrative departments in managing and controlling human ac-tivities in nature reserves. Results show that human activities did exist in 405 national nature reserves, covering a total area of 2. 424 3 million hectares, or 2. 58% of the total area of the national nature reserves in China. In addition, human activi-ties were mainly concentrated in experimental areas of the nature reserves, covering 1. 430 6 million hectares or 59% of the total area of human activity patches. Among the types of human activity, agriculture was the major one, which could be found in 360 national nature reserves, covering a total area of 2. 110 3 million hectares.
