| 摘 要： | 基于莱州湾南部沿海地区地下水、表层土壤地球化学和地下水水位调查资料,综合分析了该地区主要环境地质问题的分布范围、形成原因和相互作用等,为问题的防护、治理和相关政策制定提供科学依据。海(咸)水入侵的程度由北向南逐渐减弱,寿光营里镇、侯镇,寒亭固堤、萧家营镇,昌邑卜庄镇、柳疃镇一线以北区域为重度入侵区,向南依次为中度入侵区和轻度入侵区;地下水超采漏斗主要有牛头镇-寿光、留吕、潍寒及昌邑四个漏斗,这4个漏斗已发展成近东西的区域性漏斗群带;土壤盐渍化程度整体上呈由北向南减弱的趋势,盐土和强度盐渍化土壤主要分布在东北部和西北部滨海地区,中度盐渍化土壤呈斑块状,主要分布于强度盐渍化土壤区外围。长期超量开采地下水是导致环境地质问题主要原因,全球气候变暖、海平面上升、降水减少、入海河流流域水库建设和海岸带地区经济建设等是重要影响因素。莱州湾南部沿海地区的防治工作应采取多种手段,开展综合治理,包括合理开发利用地下水资源;修建防潮堤、防潮闸;开展南部山区水土保持工作,减少降水流失;建立系统的监测网络,加强环境地质监测与预警等。

| Abstract: | Based on the groundwater and topsoil geochemistry data,and groundwater level data in the coastal region of southern Laizhou bay,this study analyzed the distribution patterns,genesis and interactions of primary environmental geology problems,which could provide scientific basis for the prevention,improvement and relevant policy-making for this area.The degree of seawater(saltwater)intrusion decreases gradually from the north to the south,and the most serious intrusion areas lie at the north of the line of Yingli and Hou town of Shouguang,Gu and Xiaojiaying town of Hanting,Puzhuang and Liutuan town of Changyi.Primary groundwater over-exploit funnels including Niutou-Shouguang,Liulü,Weihan and Changyi,have almost developed into a regional funnel belt.The regional funnel belt is approximately of east-west trending and stretching towards the area.As a whole,soil salinization takes on a tendency of decreasing from the north to the south.Saline and intensive salinity soils are mainly distributed on the north-east and north-west coastal regions.Moderate salinity soils are plaque scattering and mainly distributed outside of the intensive salinity soils.Long-term groundwater over-exploiting is the major reason of above environmental geology problems,and other factors such as global warming,sea-level rise,rainfall reduction,drainage basin reservoir construction and coastal region economic construction are also significant influence factors.We suggested that the government should perform multiple methods and comprehensive treatment on the prevention countermeasures,including rational development and utilization groundwater resources,for example,constructing tide barrier and tidal gate,water and soil conservation in the southern mountain area for decreasing rainfall run off,and buliding systematic monitoring network for intensive monitor and forewarning. |
