旅游资源的经济价值已得到广泛、深入的认识和挖掘，为旅游资源价值评价及其开发保护提供了借鉴。从生态角度探讨了旅游资源所具有的生产价值、服务价值、协调价值、承载价值、信息价值，对旅游资源自身的多维价值展开了相应分析，力图使旅游资源价值得到全面揭示和拓展。     

资源驱动型旅游地中心城市形象研究——以黄山市屯溪区为例

资源驱动型旅游地中心城市是我国普遍存在的一种旅游城市类型，但对这类城市形象的研究相对较少。以黄山市屯溪区为例，在感知形象测度的基础上，利用定性与定量方法论结合分析其感知形象现状和问题，并提出解决方案，总结出该类型城市在形象建设中应当注意的四对矛盾。     

生态旅游资源利用与保护主体行为的博弈分析

生态旅游资源的利用与保护过程是相关利益主体间利益协调和行为协作的博弈过程。本文通过对生态旅游资源相关利益者利益问题的博弈分析，阐释了利益主体对资源过度利用及保护不力的动因，分析了如何建立一种利益主体之间的利益博弈规则，并使它在一定条件下成为各利益主体能够共同自觉遵守和自我实施的一种内生的资源有效利用和保护制度。     

代际利他下资源分配的经济学分析

从分析可持续发展的内在要求与经济人假设之间的冲突出发，构建了利他状态下的资源代际分配效用函数。通过对非凸状偏好及利他的心理价格变化下消费均衡解的比较静态分析，作者指出。在后代人缺位情况下可以利用宏观和微观因素对当代人的利他度加以影响。实现利他的资源代际分配模式，从而在理论意义和实践意义上拓展了可持续发展理论。     

三江并流带旅游地质资源环境现状及保护

地质资源是一种重要的旅游资源，有必要对其开发，但由于旅游地质资源环境自身的脆弱性，关联性，以及人类活动对其不合理的开发和利用，都会使其毁于一旦。笔者以三江并流带旅游地质资源的开发为例，分析了三江并流带开发中旅游地质资源环境的现状、存在问题及其影响因素，并提出了旅游地质资源环境保护的建议、对策。

CITY OF TUCSON WASTE WATER EFFLUENT DELIVERY FACILITY1

ABSTRACT: The Tucson area is totally dependent on ground water, which is in increasingly short supply due to excessive overdrafts. Tucson area waste water treatment plants discharge material quantities of secondary effluent downstream, which is lost to evapotranspiration and recharge of the ground water basin. The city and the four large mining companies who share the common Santa Cruz basin ground water, recognized the common water supply problem and agreed to fund a feasibility study for mining process use of the effluent to partly alleviate the overdraft of ground water. The study analyzed the projected waste water effluent resources, potential mining company demand for waste water effluent and possible interface of an effluent delivery facility with the proposed Central Arizona Project. The effluent resources were analyzed with respect to potential demand. An optimum alignment was selected. An optimum system was detailed through design schematics, amortized cost and finance requirements, and an implementation schedule. It was concluded that a waste water effluent delivery facility could be implemented which would utilize reclaimed effluent in quantities approximating 35 percent of basin overdraft and which would provide revenue for full cost recovery over a 20 year operation period. The mining companies are studying the internal economic impacts of the project.     

THE ENGINEER'S ROLE IN WATER RESOURCES PLANNING1

Engineers have traditionally led the planning effort in water resources developments. The engineer's leadership role in water resources, as well as in many other planning activities, has been challenged by technical and scientific people as well as by the general public for insensitivity to social, aesthetic, ecological, and political problems created by planning. The paper draws attention to the fact that the engineer cannot continue to expect the role of leadership to fall to him unless he prepares himself properly for that role. However, it is brought out that the engineer, by his education and training, is still the best qualified among all the representatives of the various disciplines associated with water resources planning to lead the planning effort if he prepares himself for the task. The requirements for preparation for leading water resources planning are outlined.     

GROUND WATER IN PERSPECTIVE1

ABSTRACT. Owing to their enormous capacity, ground-water reservoirs are at least equal in importance to the ground water itself. As regulators of water movement in the hydrological cycle, these reservoirs surpass all lakes combined, natural and manmade. While many aquifers are not well understood, data on many others are adequate for long-range broad-scale planning. An example is the basalt aquifer of the Snake River Plain in Idaho. However, the area has managerial problems which concern the time, the place and the feasibility of manipulations of water. All continents of the world contain great aquifers. For every huge aquifer, however, hundreds of smaller ones occur, and even these contain astonishing amounts of water. Aquifers in the Ohio River Basin of the United States are good examples. Management of total water resources is a difficult problem at many places. But many problems could be met and many water shortages alleviated or eliminated by use of aquifers, not merely as sources of water, but as reservoirs for management of water.     

Remote sensing of coastal food resources

Since tidal marshes and estuaries cover large areas of the world's coasts and exhibit a very high net primary productivity, they offer a most important food source for an ever increasing world population. The food web of numerous estuaries and coastal waters is based on the primary productivity of coastal marshes that constitute centers of solar energy fixation and an important link in the mineral cycles. The fixed carbon and minerals enterthe water primarily as detritus where a complex food web makes them accessible to commercially important fish and benthic communities. With the launch of LANDSAT, NOAA-2, and Skylab, relatively high resolution spacecraft data became available for mapping and inventorying tidal marshes and their productivity on a global scale. Upwelling regions that attract large fish populations as well as other coastal water properties relating to the presence of finfish, Crustacea, and shellfish could be identified and observed. Using multispectral analysis techniques, classification accuracies greater than 80 percent have been obtained for most marsh plant species, and greater than 90 percent for key types such asSpartina alterniflora, which is the primary producer in large tide marshes of the coastal eastern USA. The capacity of remote sensors on spacecraft such as NOAA-2, LANDSAT, and Skylab to assess coastal food resources on a global scale is discussed from the point of view of resolution, classification accuracy, and cost effectiveness.
