Protecting Watershed Ecosystems through Targeted Local Land Use Policies
结合土地利用选择计量模型与流域健康指标模型,评估不同土地利用政策对流域生态系统的影响,发现基于激励的政策和土地收购对流域健康效果显著,而改变土地收益的政策效果较弱。
Abstract Land use change is the most pervasive force driving the degradation of watershed ecosystems. This article combines an econometric model of land use choice with models of watershed health indicators to examine the effects of land use policies on watershed ecosystems through their effect on land use. Our results suggest that incentive‐based land use policies and property acquisition programs can have relatively large positive impacts on watershed health, while policies that change the returns to land use are less effective. The results suggest that there is potential for targeting these policies because their impacts vary across watersheds with different land use mixes.
