外文参考文献（原文） Urban planning and development in Tehran Abstract:With a population of around 7 million in a metropolitan region of 12 million inhabitants, Tehran is one of the larger cities of the world. This paper charts its planning and development through the ages, particularly since the mid-20th century, a period in which the city has gained most of its phenomenal growth. Three phases are identified in this historical process, with different types of urban planning exercised through infrastructure design and development, land use regulation, and policy development. Keywords: Planning, Urban growth, Iranian cities Planning through infrastructure design and development: foundations for growth The first phase of Tehranrsquo;s planning refers to the period before the Second World War, whereby at least three major efforts set the framework for the cityrsquo;s growth and development: walling the city(1550s) , expanding the walled city (1870s) and bu

RURAL AND URBAN LAND DEVELOPMENT AND LAND TENURE SYSTEMS: A COMPARISON BETWEEN SOUTH AFRICA AND BOTSWANA Susan Bouillon Legal Advisor: City Council of Pretoria INTRODUCTION Franklin D. Roosevelt once said that lsquo;Every person who invests in land near a growing city, adopts the surest and safest method of becoming independent, for land is the basis of wealth.rsquo; The purpose of this paper is to discuss the rural and urban land development and land tenure systems of South Africa and Botswana, and to explain their contributions to urban sustainability. DEVELOPMENT PLANNING IN BOTSWANA Botswana is located at the centre of the South African plateau, and is bordered by South Africa on the south and southeast, Zimbabwe on the northeast and Namibia on the west and northwest. Approximately 23% of the population is in urban areas and 77% in rural areas. Botswana has a rich tribal culture, and therefore it is not surprising that the Botswana legal system consis

Policy and Practice In search of conceptual modernization: The new Dutch lsquo;national spatial strategyrsquo; Abstract. In the Netherlands the publication of a new policy document on spatial planning is always a milestone, as the national government is such an important player in this field. The National Spatial Strategy is no exception and, at first sight, marks a complete change of tack. Instead of emphasizing spatial quality – as usual – it concentrates on easing the restrictions on spatial development. Central government wants to take a step backwards in favour of allowing the local authorities, and in particular theprovinces, to play a key role. Although the liberal approach to development control is revolutionary, most of the spatial concepts in the National Spatial Strategy are based upon traditional ideas about spatial organization. Key words: National Spatial Strategy, spatial concepts, Spatial Planning Act, The Netherlands, urban networks 1. In

Britain is one of the worlds economic power, but also the birthplace of modern tourism, Englands unique natural, cultural and historical resources it has unique conditions for tourism development. Britain is today the worlds major tourist destinations, regional and entry into the 21st century, the British tourism development there is a new situation, the paper analyzes the status quo and the latest development of the British tourism development strategy, pointing out to our current and future tourism development an important reference value. First, the status of development of tourism in Britain Over the years, tourism has been ranked in the forefront of the UK economy, revenue second only to the chemical and financial industries. According to British media sports statistics, the British companies in the tourism industry more than 200,000, the annual direct contribution to UK GDP 52 billion pounds. Tourism practitioners total 1.36 million, accounting for 4.4 percent of total
