塔里木沙漠公路防护林生态工程是新疆防沙、治沙重大工程之一,就其建设长度和规模来讲,可谓世界之最。文中通过地下水位测量、地下水样水化学分析等数据,对防护林沿线的地下水空间变异性特征及地下水要素的空间分布规律进行了探讨,目的是为防护林带的正常生长提供理论依据和技术支撑。分析表明:在小于当前研究尺度下,影响地下水特征变异的过程作用较强。地下水埋深在整个尺度上具有恒定的变异,沿线区域北部的地下水埋深小于南部;地下水矿化度表现为中等的空间相关性,高矿化度水集中在沙漠北部;地下水pH值的空间相关性很弱,高值交替出现,最大值出现在沙漠中部位置。
Tarim Desert Highway shelter-forest ecological project is one of the major projects of sand control and sand control in Xinjiang, which is the most in the world in terms of its construction length and scale. In this paper, the spatial variability of groundwater along the shelterbelts and the spatial distribution of groundwater elements are discussed through the data of groundwater level measurement and chemical analysis of groundwater sample water. The purpose is to provide theoretical basis and technical support for the normal growth of shelterbelts. The analysis shows that the process of affecting the variation of groundwater characteristics is stronger than the current research scale. The groundwater depth has a constant variation over the whole scale. The groundwater depth in the northern part of the area is smaller than that of the south part. The salinity of groundwater shows medium spatial correlation and the high salinity water concentrates in the northern part of the desert. The spatial correlation of groundwater pH value Sex is weak, high value alternating, the maximum appears in the middle of the desert.
