人口增长和经济增长导致自然生境大规模转变为人类主导的景观，从而导致生物多样性大规模下降。保护生物多样性，同时满足人类日益增长的需求，是一个至关重要的问题。在本文中，我们开发了一个空间上明确的生态层次模型，用于分析替代土地利用模式的生物和经济后果。空间上明确的生物模型结合栖息地偏好，面积要求和分散能力之间的栖息地补丁陆生脊椎动物物种，以预测可能的物种数量，将持续的景观。空间明确的经济模型结合了场地特征和位置，以预测各种潜在土地利用的经济回报。我们应用该模型来寻找有效的土地利用模式，最大限度地提高生物多样性保护目标的经济回报水平，反之亦然。我们应用该模型的威拉米特盆地，俄勒冈州，美国。通过仔细思考活动的安排，我们发现土地使用模式可以维持高水平的生物多样性和经济回报。与1990年的土地利用模式相比，我们发现，生物多样性保护和经济活动的价值可以大大增加。(c)2008爱思唯尔有限公司保留所有权利。
Expanding human population and economic growth have led to large-scale conversion of natural habitat to human-dominated landscapes with consequent large-scale declines in biodiversity. Conserving biodiversity, while at the same time meeting expanding human needs, is an issue of utmost importance. In this paper we develop a spatially explicit landscape-level model for analyzing the biological and economic consequences of alternative land-use patterns. The spatially explicit biological model incorporates habitat preferences, area requirements and dispersal ability between habitat patches for terrestrial vertebrate species to predict the likely number of species that will be sustained on the landscape. The spatially explicit economic model incorporates site characteristics and location to predict economic returns for a variety of potential land uses. We apply the model to search for efficient land-use patterns that maximize biodiversity conservation objectives for given levels of economic returns, and vice versa. We apply the model to the Willamette Basin, Oregon, USA. By thinking carefully about the arrangement of activities, we find land-use patterns that sustain high levels of biodiversity and economic returns. Compared to the 1990 land-use pattern, we show that both biodiversity conservation and the value of economic activity could be increased substantially. (c) 2008 Elsevier Ltd. All rights reserved.
