摘要:

地下水作为黄河三角洲地区水循环的重要环节对整合土地利用和水循环管理及河口湿地自然保护区的存在和发展具有重要意义。论文以黄河三角洲为研究区,对地下水埋深的时空变化及其对土壤剖面电导率的影响进行了研究。结果表明：在黄河两岸,地下水埋深向两侧递减,在沿海地区地下水埋深较浅,并且受到不同尺度的结构因素和随机性因素的共同作用,地下水埋深具有中等强度的空间自相关性。采用地下水埋深和30cm、100cm土壤电导率的相关分析结果表明：土壤剖面电导率与地下水埋深具有一定的相关性,地下水埋深值越小,土壤电导率越大,且地下水埋深对100cm土壤电导率的影响大于对30cm土壤电导率的影响。该结果可为研究黄河三角洲地区土壤盐渍化预测和治理以及地下水循环管理提供支持。

Abstract:

Groundwater is an important part of the water cycle in the Yellow River delta, which plays an important role in drinking water, industrial water and irrigation. We used the kriging interpolation method of ArcGIS to draw the spatial distribution map of groundwater burial depth in the Yellow River delta during the normal period, the wet period and the dry period. The results show that the groundwater depth decreases in both sides of the Yellow River, and in the coastal areas the groundwater depth is shallow, and is affected by structural factors and random factors of different scales. With the help of SPSS 19.0 spatial analysis tools, the method of using bivariate analysis to study the groundwater depth and 30 cm, 100 cm soil electrical conductivity, the results show that the soil profile 30 cm, 100 cm, conductivity and groundwater depth has a certain relationship, embodied in groundwater buried depth, the smaller the value, the greater the soil electrical conductivity, and the influence of the conductivity of groundwater depth of 100 cm soil greater than 30 cm soil electrical conductivity. This research has certain significance for improving soil salinity and groundwater environment in the Yellow River delta region.
