汾河口傍河水源地激发补给量研究

该文阐述傍河水源地地下水资源构成和补给特性。利用野外试验与室内数值模拟相结合方法，分析汾河口傍河水源地可采水资源量，数值模型刻画黄河实际摆动边界，考虑潜水延迟给水和极端干旱气候条件等多种方案；利用环境同位素技术追踪傍河水源地开采条件下的河水激发补给过程和补给强度。研究表明，在渗透性较好的常年性河流旁建立的水源地，具有抵御极端气象、水文环境以丰补歉的能力，枯水年动用的含水层储存量。丰水年恢复性强。     

Sand harm in Taklimakan Desert highway and sand control

Reputed as a wonderful achievement of the world's highway construction history, the Taklimakan Desert highway is now facing serious sand drift encroachment problems due to its 447- km-long passage of sand sea consisting of crescent dunes, barchan chains, compound transverse dune ridges and complex megadunes. To solve some technical problems in the protection of the highway from sand drift encroachment, desert experts have been conducting the theoretical and applied studies on sand movement laws; causes, severities and time-space differentiation of sand drift damages; and control ways including mechanical, chemical and biological measures. In this paper the authors give an overall summary on the research contents and recent progress in the control of sand drift damages in China and hold that the theoretical research results and practices in the prevention of sand drift encroachment on the cross-desert highway represent a breakthrough and has an epoch-making significance. Since the construction of protective forest along the cross-desert highway requires large amount of ground water, what will be its environmental consequence and whether it can effectively halt sand drift encroachment on the highway forever are the questions to be studied urgently.
