中文摘要	柽柳植物以其适应干旱、盐碱等恶劣环境而自然生繁于我国干旱地区,又以其强大的防风固沙能力在干旱区备受关注.＂红柳沙包＂是干旱区颇为特异的生物景观.近数十年来,由于土地开发和樵伐等原因,柽柳植丛逐渐衰退,由柽柳植丛形成红柳沙包也被严重破坏.从20世纪80年代至今,作者在我国西部干旱区,含甘肃河西走廊西段,新疆两大盆地周围的铁路,公路沿线和库尔班通古特沙漠腹地,通过沿交通线踏查和样地实测,对由建设工程(如修建公路、铁路等)所导致的柽柳迅速扩展现象进行了研究. 研究发现在修筑公路推土机作业所形成的洼地积水区有大量柽柳植丛生长,由工程建设所引起植丛扩展现象的与该区其他地段柽柳的扩展颇相类似,但已超出其自然分布的格局.这类植物的扩展有益于中国西部地区的生态建设植被恢复,对遏制风沙,改善西部环境起到重要作用.因而有必要对柽柳植丛扩展现象进行深入研究,探索促进适宜生境柽柳植丛广泛扩展的方法和途径.参19.
英文摘要	Tamarix plant is widely distributed in the arid areas of China for its great tolerance of draught, salt and alkali and attracts more attention by its strong capacity in windbreak and sand-fixations. "Tamarix dunes " constitute special desert bio-landscape in arid area. During last several decades, Tamarix shrubs declined and "Tamarix dunes" were also severely destroyed due to the land exploitation and serious deforestation, etc. From the 1980s until now, the extending phenomenon of Tamarix shrubs caused by developmental projects such as building highway, railway was studied in the western dry area of China, including western section of Hexi Corridor of Gansu, railroads and highways around the two greatest basin in Xinjiang and interior regions in Gurbantonggut desert, through on-the-spot survey along the transportation lines and setting up sampling plots along the roads. It was found that large quantities of Tamarix plants grow in the catchment area of low-lying lands that were formed by bulldozer operation during road building period. The extension of Tamarix shrubs caused by engineering was similar to that of the other section of the area to some extent, but went beyond the original distribution. This extension is beneficial to the ecological restoration and re-vegetation of western region of China and plays an important role in control of the sandstorms and improvement of ecological environments. As a result, it is necessary to make a further study on the extending phenomenon of Tamarix shrubs and to seek approach to promote wider extension of Tamarix shrubs in suitable habitats.
