摘  要：
以6 a来塔里木沙漠公路防护林生态工程示范段主要固沙植物的生长监测资料为依据,利用SPSS统计软件,对不同立地条件下植物的生长状况进行了因子分析,得到以下结论:(1)固沙植物在粘土地生长最好,植物生长量与生长时间相关,速生期在第3~5 a;(2)固沙植物在平沙地生长次于粘土地,速生期亦在第3~5 a;(3)沙垄顶固沙植物的生长最弱,与其他两种立地类型相比差距显著,其生长曲线随年际变化波动较大,速生期在第1~3 a。

摘  要：
In this paper, the project of ecological shelterbelt construction along the Tarim Desert Highway passing through the Taklimakan Desert is researched. The Taklimakan Desert is located in the Tarim Basin in south Xinjiang, China, and its area is about 3.33×10~5 km~2. According to the meteorological data observed by Tazhong Meteorological Station, the annual air temperature and the extremely maximum temperature are (12.4 ℃) and 45.6 ℃ respectively, the annual precipitation varies in a range of 11～40 mm only, strong winds occur frequently, and the annual average wind speed and instantaneous maximum wind speed are 2.5 m/s and 20.0 m/s respectively. The elevation of the basin varies in a range of 800～1 300 m a.s.l., and the Taklimakan Desert is basically covered by mobile dunes and dune-chains varying in height from several meters to several hundred meters. In order to guarantee the unblocked traffic of the Tarim Desert Highway 522 km in length and improve the ecological environment along the highway, the "Project of Ecological Shelterbelts along the Tarim Desert Highway" is started by investing 2.2×10~8 yuan. In this paper, the growth of the shelterbelt plants under the different local conditions along the Tarim Desert Highway is analyzed based on the 6-year monitoring data of main sand-fixing plants planted along the demonstration sections of the ecological shelterbelts along the highway by using SPSS software. The conclusions are as follows: (1) The sand-fixing plants can grow best on sand sheets where a clay layer underlies, there is a correlation between the growing mass of plants and the growing time, and the rapid growing period of plants is for 3～5 years; (2) The growth of sand-fixing plants growing on sandlands is inferior than that on clay lands, and the rapid growing period of plants is also for 3～5 years; (3) The growth of sand-fixing plants growing on the top of dune-chains is the poorest, the interannual fluctuation of the growth curves of plants is high, and the rapid growing period of plants is for 1～3 years.
