Policies for Habitat Fragmentation: Combining Econometrics with GIS-Based Landscape Simulations
研究通过整合计量经济学模型与景观模拟,分析南卡罗来纳州沿海平原地区减少森林破碎化的激励政策,发现降低破碎化的成本因初始景观条件而异,简单统一补贴效果接近复杂空间定向政策。
<i>Habitat fragmentation is widely considered a primary threat to biodiversity. In this paper, we analyze incentive-based policies designed to reduce forest fragmentation in the coastal plain region of South Carolina. Our approach integrates an econometric model of land use with simulations that predict the spatial pattern of land-use change. We analyze how subsidies for afforestation affect distributions defined over fragmentation metrics and derive the marginal costs of altering landscape patterns. We find the costs of reducing fragmentation vary greatly with initial landscape conditions and that a simple uniform subsidy performs well relative to a more complicated spatially targeted policy.</i>
