Abstract

Abstract The water purification functions of forests represent one of the most frequently invoked examples of nonmarket ecosystem services that are economically valuable. This study quantifies the monetary value of forests' water purification services in the form of the ensuing cost savings of municipal drinking water treatment, using a rich panel dataset from China's Sichuan province. Moreover, this study has undertaken a novel spatial piecewise approach to investigate the spatial patterns of such cost savings delivered by forests at different distances from the water intake point. The estimation results find that forests within a 2 km radius upstream from the water intake point have the most sizeable and statistically significant cost saving effect. For forests within a 3 km radius, this effect becomes somewhat smaller but remains statistically significant. Beyond a 4 km radius, this effect becomes notably smaller and statistically equal to zero. Our analysis facilitates the optimal spatial targeting of forest conservation.

评价森林的水净化服务:基于中国四川省面板数据的生产函数方法

森林的水净化功能是最常被引用的具有经济价值的非市场生态系统服务的例子之一。本研究使用来自中国四川省的丰富面板数据集，以随后市政饮用水处理成本节约的形式量化了森林水净化服务的货币价值。此外，本研究还采用了一种新颖的空间分段方法来调查森林在离取水点不同距离上节约成本的空间格局。估算结果表明，取水点上游2公里半径范围内的森林节约成本效果最大，且具有统计学意义。对于半径3公里以内的森林，这种影响略小，但在统计上仍然显著。在4公里半径以外，这种效应明显变小，在统计上等于零。我们的分析有助于森林保护的最佳空间定位。

期刊介绍： Environment and Development Economics is positioned at the intersection of environmental, resource and development economics. The Editor and Associate Editors, supported by a distinguished panel of advisors from around the world, aim to encourage submissions from researchers in the field in both developed and developing countries. The Journal is divided into two main sections, Theory and Applications, which includes regular academic papers and Policy Options, which includes papers that may be of interest to the wider policy community. Environment and Development Economics also publishes occasional Policy Fora (discussions based on a focal paper). From time to time the journal publishes special issues based on a particular theme.
