论国家对人力资源生产和再生产的宏观调控

国家宏观调控的实质是从社会经济运行和发展的全局出发，按照预定的目标，对社会经济的决量和总体结构进行调节和管理。在社会主义市场经济条件下，人力资源的生产和再生产各个环节的经济关系错综复杂经济，人力资源生产和再生产与物质资料的生产和再生产之间也涉及方方面面的经济利益关系。市场在调节经济关系中发挥着基础性作用，但由于市场机制的运行本质上在于利益驱动，这必然造成市场失灵和市场激励机制作用的局限性，从而要求国家加强对人力资源生产和再生产中的经济关系的宏观调控。

试论多种水源的联合运用 ——以西安市为例

多种水源的联合运用是缓解乃至解决城市水荒的必然选择。运用动态规划方法，对西安市多种水源的联合供水进行了水量调配演算，得出在一般水文干旱年和特别水文干旱年可分别获得城市所需水量，并且调出水区基本不受影响，西安市地下水在多数年份得到涵养。     

Groundwater recharge through an alluvial fan in the Atacama Desert,northern Chile: mechanisms,magnitudes and causes

The Chacarilla fan in the Atacama Desert is one of several formed in the Late Miocene at the foot of the Pre‐Andean Cordillera overlying the large, complex, Pampa Tamarugal aquifer contained in the continental clastic sediments of the fore‐arc basin. The Pampa Tamarugal aquifer is a strategic source of water for northern Chile but there is continuing doubt over the resource magnitude and recharge. During January 2000 a 1 in 4 year storm in the Andes delivered a 34 million m³ flash flood to the fan apex where c. 70% percolated to the underlying aquifers. Groundwater recharge through the fan is calculated to be a minimum of 200 l/s or 6% of the long‐term catchment rainfall. These figures are supported by hydrochemical data that suggest that recharge may be 9% of long‐term rainfall. Isotopic data suggest groundwater less than 50 years old is transmitted westward through the permeable sheetflood sediments of the fan overlying the main aquifer. Analysis of this and other events shows that the hydrological system is non‐linear with positive feedback. The magnitude of groundwater recharge is dependent on climatic variations, antecedent soil moisture storage and changes in channel characteristics. Long‐term declines in groundwater level may partly result from climatic fluctuations and the causes of such fluctuations are discussed. Copyright © 2002 John Wiley & Sons, Ltd.     

西北地区土壤资源特征及其开发利用与保护

在分析西北地区土壤分布规律的基础上,研究了不同类型区土壤的资源特征及其在开发利用中存在的问题,认为黄土地区土壤土质疏松、粉砂含量高、富含碳酸钙是水土流失的物质基础;干旱区广为分布的荒漠土壤资源的性能低劣、绿洲区水土资源的利用比例失调是造成土地荒漠化、土壤盐渍化的根本原因;而高原土壤的粗骨性、土层浅薄、有效肥力低则加速了草场的退化和沙漠化.提出了西北地区土壤资源的合理利用与生态环境保护相协调的途经,即搞好农田基本建设,采用旱作技术节水和合理用水,扩大林草植被,保护天然草场和林木.并认为西北土壤资源的开发利用要在充分发挥其生产潜力的同时,首先应遵循生态规律,开发与保护并重,防止土壤资源衰竭和破坏.
