为构建一套服务于当前最严格水资源管理制度建设的海水入侵区地下水管理控制水位划定方法,在对海水入侵区地下水管理控制水位概念界定的基础上,提出了地下水管理控制水位红线-黄线-蓝线分级模式,针对地下水不同阶段的管理需求,构建了基于人工神经网络方法的地下水合理水位计算方法和基于水资源调控模型的地下水管理控制水位计算方法,并以莱州市为例,开展了基于海水入侵预防目标下的地下水管理控制水位划定。结果表明,为有效防止海水入侵,莱州市全市的地下水开采规模应控制在6 850×104 m3以内,全市地下水合理水位(平均值)控制在7.69m以上,同时2015、2020、2030年的地下水管理控制水位应分别达到7.03、7.37、7.69m。
In order to establish a set of method to demarcate groundwater management level in seawater intrusion area which serves the most severe water resource management system, based on the concept definition of groundwater management level in seawater intrusion area, According to the management requirements of different stages of groundwater, this paper constructs the calculation method of groundwater reasonable water level based on artificial neural network and the groundwater management control water level calculation method based on water resources control model. Taking Laizhou city as an example, Groundwater management and control water level demarcation based on seawater intrusion prevention target. The results show that in order to effectively prevent seawater intrusion, the scale of groundwater exploitation in Laizhou should be controlled within 6 850 × 104 m3. The reasonable level of groundwater in the city should be controlled at above 7.69m and the groundwater management in 2015, 2020 and 2030 The control water level should reach 7.03, 7.37 and 7.69m respectively.
