摘  要：
以甘肃河西走廊金塔县沙漠森林公园作为典型胡杨林地的研究区域,通过野外实地采样和植被生长状况的调查,研究不同土层土壤水盐动态变化以及对胡杨生长状况的影响.结果表明:在距离地表60cm以内,随着土层的加深,土层中水分的含量随之增高;而在60cm以下,随着土层的加深,土层水分的含量在不断减少,但变化平缓.土壤盐分的变化总体趋势为随着土层的不断加深,土层中盐分的含量在不断的减少,其中以0~10cm层土壤的盐分最高.在不同的水分和盐分条件下,胡杨林的生长状况为,随着水分的增加,不管是树高、胸径还是地径都呈现出增加的趋势,植被的生长状况也趋向良好;随着土壤含盐量的增加,植被的生长状况趋势于不良,区域植被趋于衰落.在一定条件下,土壤水盐运动是相伴而行的,土壤水分运移的过程带动了土壤盐分的运动,所以在水分和盐分共同作用下,每块样地土壤全盐量和含水量表现出相矛盾的现象.

摘  要：
Choosing Populus euphratica forest in Desert and Forest Park of Jinta County as study object,the dynamic changes of soil water and salt in different soil depths were analyzed through field sampling and investigation of vegetation growth status.The results showed as follows:1)Within the upper 60 cm soil layer,soil moisture increased with soil depth,on the contrary,soil moisture decreased with soil depth under 60 cm soil layer.2)Soil salt displayed a decreasing trend with the increasing of soil depth,and the maximum soil salt content was in 0~10cm soil layer.3)In different conditions of soil water and salt,the growth status including tree height,diameter at breast height and ground diameter of Euphrates Poplars showed different patterns.4)Under given conditions,the movement of soil moisture and salt were companied,which meant that the movements of soil moisture and salt always associated with each other,so there was contradictory phenomena of soil moisture and soil salt.
