山东省集雨增补地下水与水资源可持续利用探讨

分析了山东省水资源特点、开发利用状况以及水资源持续利用所面临的形势，在阐述山东省降雨、地理等自然特点的基础上，认为集雨增补地下水是实现水资源可持续利用的有效途径，提出了集雨增补地下水的技术措施。     

地下水资源特性及其合理开发利用

地下水资源具有以下重要特性:兼具可再生性与不可再生性,发育的系统性,以及随时间的变动性。可再生的补给资源,是理论上可持续利用的地下水资源;除了特定情况外,不可再生的储存资源只能借用而不能耗用。地下水资源发育的系统性,要求以含水系统或水文系统、而不是以含水层为单元进行地下水资源评价。由于土地利用方式的改变,地下水资源是随时间而变化的,需要根据变化情况进行再评价。根据可持续发展的理念,地下水资源评价应当遵循供水永续性和生态环境可承载性原则。地下水资源评价需要采用多种方法,相互校核,以提高其成果的信度。最后以河北平原为例,探讨了深层地下水的资源属性以及合理利用地下水的途径。     

交互式多目标决策新方法及其在水资源系统规划中的应用

在目标满意度和目标总体协调度的基础上构造了一种新的交互式多目标决策方法,运用欧式距离判断来描述目标总体协调度,避免了目标权重人为确定的任意性,且能充分体现决策者的主观愿望,便于实际操作应用.水资源系统规划的多目标决策实例分析表明该方法有效可行.     

吉林省水资源可持续利用研究

选取吉林省9城市具有代表性的7项指标,对吉林省水资源可持续利用情况进行了定量分析,采用因子分析(FA)法筛选出3个主因子——水污染排放、水环境质量和水资源,并采用层次分析(AHP)法对3个主因子的协调程度进行了可持续性评价.在分析评价的基础上,对吉林省各城市的水资源可持续利用提出了建议.

Theory and Method of Mineral Resource Prediction Based on Synthetic Information

Metallogenic prognosis of synthetic information uses the geological body and the miaeral resource body as a statistical unit to interpret synthetically the information of geology, geophysics, geo-chemistry and remote sensing from the evolution of geology and puts all the information into one entire system by drawing up digitalized interpretation maps of the synthetic information. On such basis, differ-ent grades and types of mineral resource prospecting models and predictive models of synthetic informa-tion can be established. Hence, a new integrated prediction system will be formed of metallogenic prog-nosis (qualitative prediction), mineral resources statistic prediction (determining targets) and mlaeral resources prediction (determining resources amount).     

Late Holocene climates of the Near East deduced from Dead Sea level variations and modern regional winter rainfall

The Dead Sea is a terminal lake of one of the largest hydrological systems in the Levant and may thus be viewed as a large rain gauge for the region. Variations of its level are indicative of the climate variations in the region. Here, we present the decadal- to centennial-resolution Holocene lake-level curve of the Dead Sea. Then we determine the regional hydroclimatology that affected level variations. To achieve this goal we compare modern natural lake-level variations and instrumental rainfall records and quantify the hydrology relative to lake-level rise, fall, or stability. To quantify that relationship under natural conditions, rainfall data pre-dating the artificial Dead Sea level drop since the 1960s are used. In this respect, Jerusalem station offers the longest uninterrupted pre-1960s rainfall record and Jerusalem rains serve as an adequate proxy for the Dead Sea headwaters rainfall. Principal component analysis indicates that temporal variations of annual precipitation in all stations in Israel north of the current 200 mm yr⁻¹ average isohyet during 1940–1990 are largely synchronous and in phase (70% of the total variance explained by PC1). This station also represents well northern Jordan and the area all the way to Beirut, Lebanon, especially during extreme drought and wet spells. We (a) determine the modern, and propose the past regional hydrology and Eastern Mediterranean (EM) climatology that affected the severity and length of droughts/wet spells associated with multiyear episodes of Dead Sea level falls/rises and (b) determine that EM cyclone tracks were different in average number and latitude in wet and dry years in Jerusalem. The mean composite sea level pressure and 500-mb height anomalies indicate that the potential causes for wet and dry episodes span the entire EM and are rooted in the larger-scale northern hemisphere atmospheric circulation. We also identified remarkably close association (within radiocarbon resolution) between climatic changes in the Levant, reflected by level changes, and culture shifts in this region.
