The Role of Soil Organic Carbon in Maintaining Surface Elevation in Rapidly Subsiding U.S. Gulf of Mexico Coastal Marshes

Subsidence is a primary factor governing marsh deterioration in Mississippi River deltaic plain coastal marshes. Marsh surface-water level relationships are maintained primarily through soil organic matter accumulation and inorganic sediment input. In this study we examined the role of soil organic matter accumulation in maintaining marsh elevation in a brackish Spartina patens marsh. Measured rates of soil organic accumulation were compared to plant biomass production and soil respiration (carbon dioxide and methane emission) at the study sites. The study demonstrated the importance of plant biomass production to soil organic carbon accumulation in maintaining viable Spartina patens marshes in sediment-deficient coastal environments. The role of Mississippi River freshwater reintroduction in maintaining conditions for organic accretion is discussed.

GROUND WATER NITRATE REDUCTION IN GIANT CANE AND FOREST RIPARIAN BUFFER ZONES1

ABSTRACT: Ground water contamination by excess nitrate leaching in row‐crop fields is an important issue in intensive agricultural areas of the United States and abroad. Giant cane and forest riparian buffer zones were monitored to determine each cover type's ability to reduce ground water nitrate concentrations. Ground water was sampled at varying distances from the field edge to determine an effective width for maximum nitrate attenuation. Ground water samples were analyzed for nitrate concentrations as well as chloride concentrations, which were used as a conservative ion to assess dilution or concentration effects within the riparian zone. Significant nitrate reductions occurred in both the cane and the forest riparian buffer zones within the first 3.3 m, a relatively narrow width. In this first 3.3 m, the cane and forest buffer reduced ground water nitrate levels by 90 percent and 61 percent, respectively. Approximately 40 percent of the observed 99 percent nitrate reduction over the 10 m cane buffer could be attributed to dilution by upwelling ground water. Neither ground water dilution nor concentration was observed in the forest buffer. The ground water nitrate attenuation capabilities of the cane and forest riparian zones were not statistically different. During the spring, both plant assimilation and denitrification were probably important nitrate loss mechanisms, while in the summer nitrate was more likely lost via denitrification since the water table dropped below the rooting zone.     

灾害旅游资源探讨

灾害经济学中的害利互变原理表明，灾害也有“利”的一面。它在给人类造成巨大损失的同时，也塑造了奇异独特的灾害旅游资源，其开发利用效用是其他旅游资源无法代替的。本文系统阐述了灾害旅游资源的基本属性、特性、类型及可持续开发利用的设想，以便使灾害旅游资源可以发挥更大的社会和经济效益。

矿产资源的开发利用与环境保护

作者论述了人口、资源、环境三者之间的辩证关系，提出环境保护是矿产资源开发利用的前提，不能以牺牲环境为代价来开发利用矿产资源。以此为基点，作者概述了我国矿产资源开发利用对环境的影响，以及我国矿山环境保护工作的现状，提出了加强矿产资源开发利用中环境保护的五项建议。     

矿产资源进口战略的陷阱及其对策

我国矿产总量丰富、品种齐全，但随着经济的高速发展，总体上资源出现相对短缺，结构性矛盾突出，因此必须实施矿产资源进口战略。由于种种原因，在战略实施过程中常会发生“变形”，从而产生种种可怕的陷阱。为了保障我国国家经济安全、繁荣矿业事业、促进矿产资源的合理开发利用，作者就如何避开这些陷阱提出了有关对策。
