流域水资源影子价值的空间模型

Spatial Model of Shade Value of Water along River

河流特定位置污染的累积效应对水质的影响是该点上游取水量和污染排放量的函数。本文分析了在不同的取水和排污机制下维持水质的可能性。我们给出了在环境约束条件下最优的水资源和排污配置分析解。由于累积效应,取水权和排污权的影子价值是因地而异的。

The cumulative impact of pollutants on water quality at a given location along a river is a function of prior loadings, as well as pollution and surface flows at that particular site. The question of whether it is possible to maintain water quality under alternative mechanisms for allocating surface water and pollution rights is addressed. We model the optimal allocation of surface water and pollution rights along a river with water quality constraints. Due to cumulative effects, the shadow values of water and pollution rights are contingent on location.
