Under its jurisdiction, there are 6 counties and 6 districts, i.e. Wuming County, Hengxian County, Binyang County, Shanglin County, Long’an County, Mashan County, Xingning District, Qingxiu District, Xi Xiangtang District, Jiangnan Distruct, Yongning District and Liangqing District. The city covers a total area of 22112km2, among which urban area and urban built-up area amount to 6479km2 and over 170 km2 respectively. By the end of 2007, the registered permanent population of the whole city reached 6,835,100 persons, including registered permanent population in urban area of 2,597,700 persons and permanent population in urban built-up area of more than 1,700,000 persons. Flowing through Nanning City, Yongjiang River divides the city into 2 parts – the area at the northern part of the City and the area at the southern part of the city. In the northern area distribute party, government and army organizations, commercial companies, financial agencies, scientific, educational and public health organizations as well as information industry while the southern area is a big park of commerce, service, logistics and industry. Enjoying favorable geographic position, Nanning is lying in the fringe zone of Southern China, Southwestern China and Southeastern Asian Economic Circles and is a confluence of several economic centers, including China-ASEAN Free Trade Zone, Great Mekong River Sub-regional Economic Zone, Pan-Pearl River Delta Economic Zone, Nanning-Guiyang-Kunming Economic Belt and Beibu Gulf Economic Zone. Besides, it is also an important economic center along Beibu Gulf and a key gateway and passage leading to ASEAN countries. In recent years, Nanning’s economy has developed rapidly. In 2007, the GDP of the city reached RMB106,299,000,000 yuan, increasing by 10% compared with 2006 and breaking a new record since 1994. In the same year, its energy consumption per RMB10,000 yuan output value decreased by 2.3% while financial revenue amounted to RMB15,084,000,000 yuan, a rise of 25.23%; fix asset investment reached RMB56,022,000,000 yuan, an increase of 25.27% and industrial output value totaled RMB83,088,000,000 yuan, an increase of 29.97%. Whilst rapidly developing its economy, Nanning has also put great efforts and scored tremendous achievements in improving urban environment and constructing ecological city. Since 1995, it has been awarded with honorary titles like “Sanitary City of the State”,“Model City in Comprehensive Control of Urban Environment”, “Garden City of the State”,“China’s Top Ten City in Ecological Environment Construction”, “China Habitat Environment Prize”, “UN Habitat Scroll of the Honour Awards”, etc. With the ever-increasing progress in urbanization, the fast economic development and the successive increase of the livelihood of the people, environmental pollution has progressively become a major factor withholding the social and economic development. Notwithstanding the successive strength put into the prevention and control of environmental pollutions, deteriorated pollutions along inland rivers still exist, in some sections of the inland rivers, the - 1 - NIUEP CEA Summary 1 General
