The geological condition of coalfield is much complex in china. With increasing in mining depth and drainage amount, the contradiction of drainage, water supply and environ-mental protection is becoming more and more serious. However, the contradiction can be solved by the scientific management of optimizing combination of drainage, water supply and environ-mental protection. The Philip multiple objectives simplex method used in this article has searched for a possible solution at the first step, and then it goes on searching to find out whether there is a weight number that can lead the solution to the biggest. It can reduce the randomness and diffi-culty of traditional weight method which determine the weight number artificially. Some beneficial coefficients are vague and the number is larger in the model of water resource dispatch. So the vague layer analysis method can consider these vague factors fully, combining the qualitative and quantitative analysis together. Especially, this method can quantify the experiential judge-ment of policy decider, and it will turn to be more suitable if the structure of objective factors is complex or the necessary data are absent. In the paper, the two methods above are used to solve the plans of drainage, water supply and optimizing distribution of water resource in the Zhengzhou mining district.

关键词： combination of drainage, water supply and environmental protection, Philip multiple objective simplex method, vague layer analysis method, distribution of water resource.

中始新世气候适宜期(MECO)是发生在约40.5~40.1 Ma的一次全球增温事件。目前该事件在海相环境中的响应特征已相对明晰,而对其发生前、发生期间、发生之后的陆相环境响应及差异的认识仍需进一步研究。济阳坳陷北部的沾化凹陷中始新统沙三下亚段(Es3L)为一套富有机质页岩层系,沉积连续,不仅是该区页岩油勘探的重点层位,也为开展MECO事件的陆相环境响应研究提供了详实的沉积记录。本研究利用沾化凹陷Luo69井跨越Es3L且长度约194 m的高分辨率伽马(GR)数据,开展旋回地层学分析,结合相关系数法(COCO)和演化相关系数法(eCOCO),以Es3L的底界年龄41.21 Ma为锚点,建立天文年代标尺。在此基础上,综合Fe含量、Ti/K比值、V/Al比值、TOC含量以及济阳坳陷南部东营凹陷的FY1井的磁性地层,确定MECO事件在研究区的响应时间,查明MECO事件发生前、发生期间、发生后济阳坳陷的气候和水文变化及其对有机质富集的影响。结果表明,Luo69井GR数据中的20.7~27.7 m波长代表405 ka长偏心率,通过调谐,获得GR数据的延续时间为3.34 Ma,Es3L的延续时间为2.48 Ma,与已报道的FY1井结果一致。结合年龄锚点,建立了41.77 Ma至38.43 Ma的天文年代标尺,并推定MECO事件在济阳坳陷的响应时间约为40.51~40.06 Ma,对应于Luo69井的约3045~3017 m区间。在MECO事件发生之前,气候潮湿-干旱波动较大,引起湖盆流域水动力和湖水氧化还原状态出现较大变化;MECO期间,气候更加潮湿,使得流域水动力增强,导致湖水富氧,但该时期TOC含量整体较高,可能与较高的初级生产力有关;在MECO事件发生后,气候变化幅度较小,相对稳定,相比事件发生前更加潮湿,TOC较事件发生前略有升高,主要受控于升高的初级生产力。

A quantum secure direct intercommunication scheme is proposed to exchange directly the communicators＇ secret messages by making ase of swapping entanglement of Bell states. It has great capacity to distribute the secret messages since these messages have been imposed on high-dimensional Bell states via the local unitary operations with superdense coding. The security is ensured by the secure transmission of the travel sequences and the application of entanglement swapping.

农业绿色低碳发展是实现农业现代化和经济高质量发展的重要途径,针对农业面源污染严重、农产品质量安全隐患凸显、农业碳排放增加等问题,山东省推动农业绿色低碳转型势在必行。本研究构建了山东省农业绿色低碳转型水平评价指标体系,采用熵权法对2011—2021年山东省农业绿色低碳转型水平进行测算,从整体、经济圈和地市3个层面分析了农业绿色低碳转型水平的时空分异情况,采用自然断点法对山东省进行分类分析,通过地理探测器揭示山东省及三大经济圈农业绿色低碳转型的关键驱动因素。研究发现:1)山东省农业绿色低碳转型的总体水平呈现稳步增长态势,年均增长率达2.310%。2)16个地市的农业绿色低碳转型水平均呈明显上升趋势,青岛、济南连续11年领跑,而临沂、潍坊、威海连续11年位居16个地市的尾部。3)省会经济圈的农业绿色低碳转型水平一直处于领先水平,其次为鲁南经济圈,胶东经济圈的水平则相对较低。4)财政支农政策、农业科技投入、农业产业结构调整是山东省农业绿色低碳转型的关键驱动因素。农业产业结构调整是省会经济圈最重要的驱动因素,城镇化水平是胶东经济圈最重要的驱动因素,政策扶持力度是鲁南经济圈最重要的驱动因素,且各因素交互产生的驱动作用程度高于单因素。基于此,山东省应以政策引领激发内生动力,强化头雁的示范带动作用,因地制宜地探索绿色低碳创新路径。
