Abstract:

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 analysis 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 activities 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 activities 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.
