摘要: 空间直观景观模型已是当前景观生态学研究的一大热点.空间景观模型模拟空间格局变化,其模拟结果包含非空间数据和空间数据.空间直观景观模型的验证除进行非空间数据的验证外,还需要进行空间数据的验证.本文回顾了空间直观模型发展历程,总结现有的空间直观模型验证方法,包括主观评价、图形比较、偏差分析、回归分析、假设检验、多尺度拟合度分析和景观指数分析,同时提出今后空间直观景观模型验证方法研究的重点方向.

Abstract: The spatially explicit landscape modeling is a now highlighted concern in the study of landscape ecology. Spatially explicit landscape models are designed to simulate ecological processes at landscape scale on heterogeneous landscapes. Their outputs include both non-spatial data and spatial data. Thus, spatially explicit landscape model validation not only includes non-spatial data validation but also spatial data validation, which is a great challenge for traditional validation method developed from the validation of non-spatial data. In this paper, we reviewed the development of spatially explicit Landscape models and the available methods for spatially explicit Land scape model validation. The key area of future study on spatially explicit landscape model validation was also identified.

Key words: Principle grain production area, Agricultural resources and environment, Systematic identification, Macro regulation
