湄洲湾海水环境质量和水产业发展的关系

通过１９９５ 年１２ 月～１９９６ 年１ 月湄洲湾渔业资源调查和生物体内残毒分析，结合１９８８ ～１９９６ 年的生态环境综合调查资料，探讨以石化工业为主体的开发对湄洲湾水产业的影响。结果表明，工业发展中污染物的排放对湄洲湾生态环境和生物的不良影响正在显现，并对水产业的发展构成威胁，但在严格控制污染物排放，保护并发展水产业的情况下，湄洲湾仍能较长期保持现有的各种使用功能，维护湾内海域的生态平衡。

Fisheries management: integrating societal preference, decision analysis, and ecological risk assessment

Fisheries management is the practice of analyzing and selecting options to maintain or alter the structure, dynamics, and interaction of habitat, aquatic biota, and man to achieve human goals and objectives. The theory of fisheries management is: managers or decision makers attempt to maximize renewable `output' from an aquatic resource by choosing from among a set of decision options and applying a set of actions that generate an array of outputs. Outputs may be defined as a tangible catch, a fishing experience, an existence value, or anything else produced or supported by renewable aquatic resources. Overall output is always a mix of tangible and intangible elements. However defined, management goals and objectives are essential components of fisheries management or any other field of renewable natural resource management. Reaching consensus on management goals and objectives has never been a simple task. Beyond the broad and often conflicting goals of an agency, managers must decide who should set specific management objectives — agency personnel, the public, or a combination of the two. Historically, rhetoric aside, fisheries managers in North America nearly always have consulted with professionals in governmental roles to set management objectives. In a strongly pluralistic society, this often resulted in protracted political and legal conflict. Increasingly, there are calls for use of risk assessment to help solve such ecological policy and management problems commonly encountered in fisheries management. The basic concepts of ecological risk assessment may be simple, but the jargon and details are not. Risk assessment (and similar analytical tools) is a concept that has evoked strong reactions whenever it has been used. In spite of the difficulties of defining problems and setting management objectives for complex ecological policy questions, use of risk assessment to help solve ecological problems is widely supported. Ecological risk assessment will be most useful (and objective) in political deliberations when the policy debate revolves around largely technical concerns. To the extent that risk assessment forces policy debate and disagreement toward fundamental differences rather than superficial ones, it will be useful in decision making.     

新疆玛纳斯河流域农业水资源可利用潜力分析

结合新疆玛纳斯河流域水文水资源、种植结构和节水技术发展等资料,从开源、节流两方面对流域近期(至2010年)、中远期(2010-2030年)农业水资源极限潜力、可挖掘潜力进行了估算。结果表明,就目前水资源的利用水平和开发趋势,玛纳斯河流域未来农业水资源的主要利用途径是开源与节流相结合,以节流为主。全流域尚有的农业灌溉水资源极限潜力为10.75×10⁸m³,近期农业水资源可挖掘潜力为2.13×10⁸m³,其中开源增水潜力0.40×10⁸m³,占18.8%,节流增水潜力1.73×10⁸m³,占81.2%;中远期农业水资源可挖掘潜力5.33×10⁸m³,其中开源增水潜力1.12×10⁸m³,占21.0%,节流增水潜力4.21×10⁸m³,占79.0%。该研究对区域制订节水灌溉规划及水资源系统优化配置具有重要参考价值。
