新疆主要自然灾害及其减灾策略

新疆是一个自然灾害较多的地区,地震灾害、地质灾害、气象灾害、洪水灾害都比较频繁。本文在概述、分析上述灾害的基础上,提出了减轻自然灾害的策略。     

论效应空间与有偿减灾投入心理对策

本文提出了减灾效应空间问题,并分析了其在有偿减灾中的作用机制,以及与其有关的减灾投入心理与费用支付合理化问题。进而探讨了宣传、强制、分割、别类、约束、归并等促进有偿减灾良性发展的部分机理。     

减灾平衡点

文章依据经济学的原理提出了减灾平衡点的概念,并初步分析了它的特征及其实际意义。所谓减灾平衡点是指社会总体投资利益最大时减灾投资在社会总投资中所占的位置;此时,减灾投资利润率与社会正常生产投资利润率相当。     

MODEL STUDIES OF SALT WATER INTRUSION1

Model studies were and are still being used to verify certain theories in ground-water flow systems in general. In complex cases, the model studies may be extremely useful especially when a theoretical rigorous analysis does not exist. The models cannot be considered entirely satisfactory due to the several drawbacks in each type in addition to the normal human errors in experimentation. This paper is concerned only with the viscous flow models. However, a brief summary of the other types of models, which may possibly be used in connection with salt water intrusion problems is given. It should be noted that some of such experiments are not directly related to the field of salt water intrusion. Two main types lie within this category: The gravity flow systems which are analogous to some phases of salt intrusion problems and problems in oil fields which bear general similarities to sea water intrusion zones. In oil fields, gas cycling studies give valuable information to sea water problems. Model studies are used by hydraulic engineers, geologists, petroleum engineers, physicists, foundation engineers and several other professional groups.     

MANGANESE CYCLE IN IMPOUNDMENT WATER

Manganese entering impounded water will undergo a cyclic transformation. Oxidation precipitates manganese from top waters. At the bottom of the lake, biological activity will render manganese soluble by both intracellular as well as extracellular activity. The study was made to demonstrate that biological reduction and transformation, organometallic complexation, together with the presence of carbon dioxide and the lowering of pH all have some effect on the solubility of manganese. Dissolved manganese may be brought back to top waters during the lake overturn and therefore deteriorates the water quality.
