描述和论证了一种基于历史土地利用图和基于模型和规划文件的预测来模拟土地覆盖格局的方法。该方法基于土地利用图和规定的转换规则，使用随机空间模拟来生成土地覆盖模式。转换规则采取以下形式：(1)汇总每种土地利用类型中每种土地覆盖类型的比例的表格；(2)对土地覆盖类型的空间安排和/或格局的描述。在该方法的演示中，我们使用航空照片观测和模拟美国密歇根州利文斯顿县的当前和未来土地覆盖地图来校准转换规则。我们在一个未用于校准翻译的测试区测试了该方法。对每种土地利用类型中的土地覆盖比例进行了合理的估计，但校准点中相同土地利用的数量较少的情况除外。位置规则的使用大大提高了试验区估计的土地覆盖模式与观测模式的匹配程度。本文讨论了如何使用该方法在基于土地覆盖格局的土地利用情景及其生态影响之间建立桥梁。
An approach to simulating land-cover patterns based on historical land-use maps and forecasts based on models and planning documents is described and demonstrated. The approach uses stochastic spatial simulation to generate land-cover patterns on the basis of a land-use map and stated translation rules. The translation rules take the form of (1) a table that summarizes the proportions of each land-cover type within each land-use type and (2) a description of the spatial arrangement and/or pattern of land-cover types. In a demonstration of the approach, we calibrated the translation rules using aerial photo observations and simulated current and future land-cover maps for Livingston County, Michigan, USA. We tested the approach in a test area that was not used in calibrating the translation. The proportions of land cover within each land-use type were reasonably well estimated, except where the amount of the same land use was small in the calibration site. The use of location rules significantly improved the fit of estimated land-cover patterns with observed patterns for the test area. The paper discusses how the method can be used to bridge land-use scenarios and their ecological impacts based on land-cover patterns.
