| 摘 要： | 在塔里木沙漠公路沿线两侧建立植物固沙体系时首先应确定适宜的灌溉方式。从1998年开始，我们根据不同灌溉方式本身的优缺点与前期试验结果，结合立地条件，在塔里木沙漠公路L292处选择沟灌、畦灌与滴灌进行植物固沙灌溉方式比较试验，对不同灌溉方式植物生长状况、沙层直渍度变化、制度及成本投入比较分析后认为，滴灌不受起伏沙丘地形限制，水利利用效率高，能够保证植物正常生长，且费用最低，因而是塔里木沙漠公路植物固沙的首选灌溉方式。

| Abstract: | Determininga suitable irrigation manner is a key problem for establishing sand fixation plantation system along Tarim Desert Highway. A series of comparison experiment about furrow irrigation, basin irrigation and drip irrigation, according to the merits and demerits themselves, the former research results and site conditions, were made on the plot L292 along the Highway. After comparing and analyzing the plant growth,the changes of salts content in the sand layer and the irrigation system as well as the cost input, it is concluded that drip irrigation is the best irrigation manner for constructing sand binding plantation along Tarim Desert Highway because it is not influenced by dune landform, it ensures plant regular growth and its water utility efficiency is the highest as well as its cost is the lest. |
