城市地下水可采资源与管理模型研究中的几个问题：以河南漯河市为例

文章以漯河市为例说明了城市地下水最大可采资源的确定和开发管理中遵循不断变化着的实际情况,走科研与生产相结合道路的必要性。全文分3个方面介绍了开采条件下的人工串层补给,随机边界条件及地下水管理模拟中常见的几个核心问题的处理。文章最后强调,地下水数值模拟中辅以同位素年龄研究的重要性。     

Isotopic compositional Characteristics of Terrigenous Natural Gases in China

The C and H isotopic compositions of the methane in more than 160 gas samples from 10 basins in China are presented in this paper.The natural gases are classified as four types: biogenic gas ,bio-thermocatalytic transitional gas, gas associated with condensate oil ,and coal-type gas. The isotopic compositions of these gases closely related to the depositional basins, the types of organic matter,the stages of thermal evolution and the genetic characteristics of different gas reservoirs.Studies of the C and H isotopic compositions of terrigenous natural gases will provide valua-ble information on the prospecting and development of natural gases of different genetic types.     

黔西高原岩溶水文地质特征及地下水资源勘察方法研究

黔西高原是指贵阳市以西至盘县一带,与云南省相毗邻。有六盘水、贵阳近郊和织金等煤田,是贵州煤炭工业的重要基地。 本区地处长江流域、乌江水系和珠江流域之北盘江水系的分水岭地带。两条水系其支流河溪是高原内的主要地表水体,径流短,对煤矿供水意义不大,因此有供水意义的水资源主要来自于本区广泛分布的三叠统碳酸盐类和下二叠统栖霞组、茅口组及石炭系摆佐组、黄龙组、马平组碳酸盐岩类岩溶含水层。
