重庆市沥鼻峡背斜地热地质特征

采用经验总结法和文献研究法，通过对沥鼻峡热储构造上的温泉和地热井勘查资料进行系统研究，发现沥鼻峡背斜具有典型的层状热储结构特征，是目前华蓥山复式背斜钻获地热水水温最低的热储构造，地热水以硫酸钙型水质为主，目前已知地热井和温泉具有水温普遍低于37℃和水量衰减较明显的特征.初步认为钻获地热水温低可能与构造有一定的关系.     

对太白山旅游资源开发与保护的探讨

太白山具有丰富而独特的地质、生物和自然景观,气势磅礴、变化万千,而为古今中外科学家和文人学士所向往。太白山第四纪冰川遗迹保存完整;生物资源丰富多彩,仅珍稀动物如熊猫、金丝猴、羚牛、大鲵(娃娃鱼)等就有10多种。太白山已被列为国家级自然保护区。对该区旅游资源必须在切实加强保护的前提下合理开发利用,为此,本文对其开发与保护规划提出探讨性意见。     

新疆库松木切克山喇嘛萨依式铜矿的勘查标志

本文通过对库松木切克山喇嘛萨依铜矿地质特征及控矿因素的研究,总结出该类矿床的若干勘查标志,其中地层层位、含矿岩相、地球化学异常、容矿岩石、围岩蚀变、活化脉体及同生断裂等最为明显。在区域内如能确定出这些标志,尤其是标志组合的存在,则将可能取得该类矿床找矿的新突破。

四川少数民族自治区域旅游开发与贫困缓解

四川少数民族自治地区是一个贫困面大、贫困程度深的区域。但它有着非常丰富的自然生态和民俗风情旅游资源,旅游业有着其他产业所无法比拟的资源优势。近年来,旅游业已成为区域新的经济增长点和国民经济的先导产业,将旅游开发与扶贫有机结合应该成为缓解贫困的有效的途径。但旅游扶贫功效的发挥是有条件的,并不是所有的旅游形式都具有同等的扶贫功效。为此文章论述了有利于贫困缓解的旅游发展战略。

Manifestation and measurement of the fractal characteristics of karst hydrogeological formations

A new method of estimating the fractal dimension of the percolation backbone of karst systems, which are discharged through karst springs, is presented. This method is based on the simulation of the spring by the MODKARST deterministic mathematical model. Application has been made to the Psiloritis karst formation in Crete, which feeds the periodically brackish karst spring “Almiros” in Crete. Furthermore, the estimated dimension justifies an independently determined power law that quantifies the sea intrusion into the karst system.

THE VARIATION OF THE SPRING PRECIPITATION IN GUANGZHOU AND ITS PRECURSORY SIGNALS

Guangzhou spring rainfall mainly exhibits interannual variation of Quasi-biannual and interdecadal variation of 30 yrs, and is in the period of weak rainfall at interdecadal time scale. SST anomalies (SSTA) of Nino3 are the strongest precursor of Guangzhou spring rainfall. They have significant positive correlation from previous November and persist stably to April. Nino3 SSTA in the previous winter affects Guangzhou spring rainfall through North Pacific subtropical high and low wind in spring. When Nino3 SSTA is positive in the previous winter, spring subtropical high is intense and westward, South China is located in the area of ascending airflow at the edge of the subtropical high, and water vapor transporting to South China is intensified by anticyclone circulation to the east of the Philippines. So Guangzhou spring rainfall is heavy. When Nino3 SSTA is negative, the subtropical high is weak and eastward, South China is far away from the subtropical high and is located in the area of descending airflow, and water vapor transporting to South China is weak because low-level cyclonic circulation controls areas to the east of the Philippines and north wind prevails in South China. So Guangzhou spring rainfall is weak and spring drought is resulted.     

四川理塘毛垭温泉地质构造环境及成因分析

通过理塘毛垭温泉现场实地考察,对毛垭温泉所处的地质构造环境及泉华层堆积层的组成、成因和物质来源进行研究。分析认为,毛垭温泉属于义敦—理塘、理塘—德巫活动断裂带上出露的构造上升泉,断裂带构造裂隙为温泉水通道;温泉水的来源是中深层循环热水与浅层地下水补给冷水混合体;其水温水量的变化受区域构造应力的控制,它的变化能反映这一区域构造应力场的动态变化信息。
