建三江分局地下水资源系统复杂性测度分析

摘要

In order to describe the complexity characteristics of groundwater resources system in Jiansanjiang Branch Bureau,the complexities of each monthly groundwater depth series in the farms belonging to Jiansanjiang Branch Bureau were measured by the mode entropy method and the regional differences of groundwater resources system complexity in the farms belonging to Jiansanjiang Branch Bureau were analyzed by utilizing the visualization function of ArcGIS technology.The measure and analysis results showed that the complexities of each monthly groundwater depth series in farms like Subarea 7 of Farm Qindeli were stronger,and that farms like Subarea 5 of Farm Yalvhe were weaker.Mode entropy could reflect the dynamic change degree of groundwater depth and had advantages like high efficient and fast,which provided a new way to research hydrological series complexity.The research achievements revealed the complexity and its arealvariation of local groundwater resources system,and screened boundary parameters for structuring water resources optimization allocation models,and provided scientific basis for rationally utilizing and developing groundwater resources in Jiansanjiang Branch Bureau and even in the whole Sanjiang Plain.%为描述建三江分局地下水资源系统的复杂性特征，采用模式熵方法对其下属农场逐月地下水埋深序列复杂性进行了测度分析，并借助ArcGIS技术的可视化功能实现了建三江分局各农场地下水资源系统复杂性的区域差异分析。测度与分析结果表明：勤得利农场7区等8个农场逐月地下水埋深序列复杂性较强，鸭绿河农场5区等7个农场逐月地下水埋深序列复杂性较弱，模式熵能反映地下水埋深动态变化程度，具有运算高效快捷等优点，为水文序列复杂性研究提供了一种新途径。研究成果揭示了该地区地下水资源系统的复杂性特征及其地域差异，为水资源优化配置模型构建率定了边界参数，为建三江分局乃至整个三江平原合理利用与开发地下水资源提供了科学依据。
