This study investigated oasis evolution and the changes of peripheral desert in the Sangong River Basin since the 1950 s by rebuilding seven land cover maps derived from black-and-white aerial photographs（1958, 1968, and 1978）, a color-infrared aerial photograph（1987）, Landsat Thematic Mapper（TM） imagery（1998）, Satellite Pour l＇Observation de la Terre（SPOT） imagery（2004）, and Landsat Operational Land Imager（OLI） imagery（2014）. The results showed that：（1） Since 1950, the oasis consecutively expanded more than four times from an alluvial fan to an alluvial plain, causing the shrinkage of desert landscapes that were dominated by a Haloxylon ammodendron Bunge community（HBC） and a Tamarix chinensis Lour community（TLC）. Furthermore, the primary（1958–1968） and final（2004– 2014） stages were the most important periods, during which agricultural land experienced the most rapid expansion during the period 1958–1968, and the built-up area showed the most rapid expansion after the 2000 s.（2） Two basic management modes, a ＂local mode＂ formed by the local governments and a ＂farm management mode＂ developed by Xinjiang Production and Construction Corps, together promoted oasis evolution under various land-use and landcover（LULC） stages.（3） The evolution of the modern oasis during the 1950s–2004 showed the general features of an arid oasis, while during the period of 2004–2014 it was characterized by a large-scale inter-basin water diversion or the import of new water sources.（4） The oasis expanded at the expense of desert vegetation, resulting in distinct variation in the structure of the desert plant community, which will make it more difficult to protect the desert ecosystem.

It is essential to determine the heavy metal concentrations in sewage sludge to select appropriate disposal methods. We conducted a national survey of heavy metal concentrations of sewage sludge samples from 107 municipal sewage treatment plants located in 48 cities covering the 31 provinces and autonomous regions, as well as Hong Kong, Macao and Taiwan by Xinjiang Production and Construction Corps in 2006, and identified the temporal trends of heavy metal contents in sewage sludge by comparison with surveys conducted in 1994-2001. In 2006, the average concentrations of As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn in sewage sludge were 20.2, 1.97, 93.1, 218.8, 2.13, 48.7, 72.3, and 1058mg.kg-1, respectively. Because of the decreased discharge of heavy metals into industrial wastewater in China and the increasingly stringent regulations governing the content of industrial wastes entering sewers, the average concentrations of Cd, Cr, Cu, Hg, Ni, Pb, and Zn have decreased by 32.3%, 49.7%, 54.9%, 25.0%, 37.2%, 44.8%, and 27.0%, respectively, during the past 12 years. The concentrations of Cd, Cr, Cu, Ni, and Zn in the samples exceeded the heavy metal limits of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant in China （GB 18918-2002） by 6.5%, 3.7%, 6.5%, 6.5%, and 11.2%, respectively. From these results, 85 of the 107 municipal sludges analyzed would be considered suitable for land application.

中华人民共和国国务院新闻办公室 2014年10月北京 前言屯垦戍边是中国几千年开发和保卫边疆的历史遗产。中央政府在西域新疆大规模屯垦戍边始干2000多年前的西汉，以后历代沿袭。1949年新疆和平解放，1954年中央政府决定在新疆成立生产建设兵团。这是符合中国国情和新疆实际的战略举措，也是历史经验在新的历史条件下的继承和发展。
