Numerical Modelling of Dissolving and Driving Exploitation of Potash Salt in the Qarhan Playa——A Coupled Model of Reactive olute Transport and Chemical Equilibrium in a Multi-component Underground Brine System

Firstly, the macroscopic chemical equilibrium state of a series of chemical reactions between intercrystal brine and its media salt layer (salt deposit) in Qarhan Salt Lake was studied by using the Pitzer theory. The concept of macroscopic solubility product and its relation with accumulated ore dissolving ratio were presented, which are used in the numerical model of dissolving and driving exploitation of potassium salt in Qarhan Salt Lake. And secondly, with a model forming idea oftransport model for reacting solutes in the multi-component fresh groundwater system in porous media being a reference, a two-dimensional transport model coupled with a series of chemical reactions in a multi-component brine porous system (salt deposits) was developed by using the Pitzer theory.Meanwhile, the model was applied to model potassium/magnesium transport in Qarhan Salt Lake in order to study the transfer law of solid and liquid phases in the dissolving and driving process and to design the optimal injection/abstraction strategy for dissolving and capturing maximum Potassium/Magnesium in the mining of salt deposits in Qarhan Salt Lake.

浅析长白山自然保护区旅游发展中的生态环境保护问题

长白山自然保护区是我国建立较早的和典型的自然保护区之一,其主要功能是进行自然生态环境的保护。但是,为了克服保护资金短缺境况,长白山自然保护区将发展旅游业作为生态环境保护工作资金支持的一条途径,而旅游业曾长期被认为是对生态环境影响微乎其微的产业,但自长白山开始发展旅游业以来,经济效益的实现似乎掩盖了原本的生态环境保护目标。本文在分析了长白山旅游发展对生态环境造成的负面影响之后,提出了一系列在长白山旅游发展过程中生态环境的保护措施,以期兼顾长白山自然保护区发展和保护两大目标的实现。

基于泛珠三角的广东工业旅游探讨

基于建立泛珠三角的研究背景，通过对广州发展工业旅游的条件的分析得出结论，认为由于地缘关系和历史原因，在泛珠三角的成员中，广东最早接受香港地区的经济辐射，港澳台投资者在广东大量投资建厂，工业优势也日渐凸显，这种得天独厚的优势，为广东发展工业旅游奠定了坚实的基础。并通过对广东工业旅游示范点和其他适合发展工业旅游的企业进行调查分析和实证研究，总结了广东发展工业旅游的主要客源类型，并对广东工业旅游的发展提出了几点发展思路。工业与旅游相结合，两者完全可以达到双赢，并可以得到一定的社会效益，也是结论性认识。
