摘 要：
塔里木公路防护林生态工程建设是在沙漠腹地生物防沙试验研究的基础上,依据公路沿线自然条件和立地条件,选择和确定防护林生态工程营建的植物种、林地结构布局以及灌溉方式。塔里木公路防护林生态工程全长436km,林带宽度72～78m,林带面积3128hm~2；植物种选用抗逆性极强的柽柳、沙拐枣、梭梭、胡杨、沙枣等灌木及乔木；树种配置采用行间混交,林带结构选用株行距为1m×2m或1m×1m；整体布局包括阻沙带和固沙带；灌溉方式为滴灌；水源为公路沿线的高矿化度地下水。初步观测表明,防护林工程防护效益和环境改善作用明显,防护林灌溉取水没有对地下水环境形成负面影响。

摘 要：
The Shelter-forest project of the Tarim Desert highway was approved and carried out in 2003 on the base of research results of the natural conditions and sites situations along the Tarim Desert highway and the experimen- tal research results of the shelter-forest construction in the center of the Taklimkan Desert.In the project,the key problems are to select plant specie and determine the structures of the forest belts and the irrigation mode and quota according to the differences of the site conditions.The project,starting from Xiaotang and reaching the National Highway 315,through the Taklimakan Desert from north to south,has an area of forest belt of 3 128 hm2 with 436 km long and 72～78 m wide.In the project,about 20 million shrubs of Calligonum,Tamarix,Haloxylon and arbors of E.angustifolia L.and P.euphratica Oliv.have been planted and local groundwater with high salinity at 3～15 g/L was utilized to irrigate forest.The plant species in the shelter-forest were mixed among rows with spacing in the rows about 1 m×2 m or 1 m×1 m.The shelter-forest consists of sand-blocking forest belts and sand-stabilizing forest belts.Meanwhile,the drip irrigating system has been set up,including 114 water supply wells,114 sets of generator,water pump and water supply header,959.2 km main water supply pipe,1 018 km branch pipe,19184 krn capillary pipe and so on.Preliminary observations indicate that the shelter-forest project of the Tarim Desert highway had significant effects in sand protection and environment improvement,groundwater intake for shelter-forest irrigation didn't result in negative influence on groundwater environment along the Tarim Desert highway.
