| Abstract: | 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 ofTamarix 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 ofTamarix plants grow in the catchment area of low-lying lands that were formed by bulldozer operation during road building period.
The extension ofTamarix 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 ofTamarix shrubs and to seek approach to promote wider extension ofTamarix shrubs in suitable habitats.
Foundation Item: This study is supported by key projects of National Natural Science Foundation (39730100), National Foundation (30070640)
and part of Project 973(G19990435).
