The Danube Delta is very large with diverse resources which have been intensively exploited during the modern period. It is now of great interest to conservationists with 280 species of birds (177 of which hatch in the delta). The origin of the delta is considered and its development is traced from the initial offshore bar, referring to the writings of the classical scholars and other sources. Modern developments involve the navigational work of the European Commission of the Danube (set up in 1856) and the more intensive exploitation of the reed beds, fisheries, agricultural lands and forests since 1950. Since the revolution of 1989 this programme has stopped and the delta (including the Razim-Sinoie lake complex) is now a Biosphere Reserve. The reserve is described and the principles for management are discussed.  相似文献

Geography emerged as a separate school discipline in the educational system of China in the 20th century. The history of its development had several distinct periods, but is largely divided into pre and post 1949. After 1949, the educational system in general underwent major changes that resulted in increasingly greater amounts of geography in the curriculum, especially at the junior middle school level. A major influence during the period came from the Soviet Union's educational system. Following the Cultural Revolution, school curriculum went through another period of change. Three national Drafts of the Teaching Plan issued by the Ministry of Education since 1978 have each made changes in the teaching of geography. The most recent takes effect in 1990. Through teacher education in normal colleges and universities and inservice teacher training, China is addressing the persistent problems of teacher preparation and school equipment in geography.  相似文献
