遥感资料在青海草地资源监测及评价中的应用研究

利用EOS/MODIS、NOAA/AVHRR卫星遥感监测的植被指数(NDVI)、地面定点监测的实际地上牧草产量资料,依据卫星遥感监测原理,在点和面上研究、建立了植被指数与牧草产量之间的关系模式,给出了草地资源卫星遥感监测和评价方法。监测和评价结果显示:2004年青海省草地资源从东南部向西北部逐渐递减,产量最高区处于黄南州南部和果洛州东南部,最低区处于西北部的柴达木盆地,近20年来天然草地资源的分布规律没有发生变化,但草地生产力在逐步下降,草地资源在逐年减少,仅果洛州全州平均牧草产量比1986年下降了4.04%,牧草总量减少85.10×104t,理论载畜量减少了63.11×104只绵羊单位;暖干旱化的气候变化趋势是造成青海省天然草地生产力下降、呈现退化趋势的主要原因。

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.
