人类的经济活动,对自然景观的改变起着主导作用。由于长期对自然资源的不合理开发利用,破坏生态平衡,因此出现了如物种绝灭、自然资源日趋减少、环境污染等带普遍性的社会问题,同时也引起了世界各国对解决这些问题的极大重视。人们越来越意识到不论是为长远利益还是当前利益,在开发和利用自然资源的同时,都必须加强对自然资源的保护与管理,并为此采取了各种措施。建立自然保护区便是其中之一。 目前,世界上很重视建立自然保护区的工作。自二次大战以来,相继建立了许多自然资源保护组织和各类型的自然保护区。现在有些国家,如美国、西德、扎伊尔、肯尼亚、坦桑尼亚等,自然保护区的面积已达国土面积的10％以上,个别国家如日本,甚至达到25％。自然保护区所占国土面积的比例,以及管理和利用水平,已上升到衡量一个国家科学文化水平标志
Human economic activities play a leading role in changing the natural landscape. Due to the unreasonable exploitation and utilization of natural resources and the destruction of ecological balance, social problems such as the extinction of species, declining natural resources and environmental pollution have emerged as a result of long-term unreasonable development and utilization of natural resources. At the same time, Great importance. People are becoming more aware of the need to strengthen the protection and management of natural resources both in the long run and in the current interest while developing and utilizing natural resources. Various measures have been taken to that end. One of them is the establishment of nature reserves. At present, the world places great emphasis on the establishment of nature reserves. Since the Second World War, many natural resource protection organizations and various types of nature reserves have been set up one after another. Now some countries, such as the United States, West Germany, Zaire, Kenya and Tanzania, have reached more than 10% of the country’s total land area. Even some countries such as Japan have even reached 25%. The proportion of land area covered by nature reserves and the level of management and utilization have risen to the standard of a country’s science and culture
