摘要
土地变化是人类对地球影响的重要表现形式,建模与预测是未来全球环境变化和可持续发展研究的重要支撑,土地变化模型广受关注。常见模型的输入为土地利用/覆盖数据,通过设置未来的类型需求量进行变化模拟,但鲜有考虑模拟单元中的土地利用强度或覆盖类型占比,难以精细地模拟复杂需求下的土地变化。2013年,CLUMondo模型发布,因能解决这些问题备受关注,特色在于能够建立土地利用强度(或类型占比)与多种间接的土地需求(如粮食产量和就业岗位数)之间复杂的供需关系。本文旨在对CLUMondo模型及相关研究进行系统综述,包括核心原理、文献计量分析、模型应用与改进。同时,展望CLUMondo模型的应用前景,可能成为未来土地变化的核心模型。
Land change is an important form of human impact on the earth,and its modeling and prediction provide huge supports for the research of global environmental change and sustainable development.Therefore,land change models are widely concerned.The input of common models is land use/land cover data,and the future area of each land type drives land change.The land use intensity and land cover proportion are rarely considered and land change is hard to be accurately simulated under complex demands.CLUMondo gains attention for its ability to address these problems.This land change model can establish a complex relationship between the land use intensity(or the proportion of land use types)and various indirect demands for land,such as food production and the number of jobs.This paper aims to systematically review the CLUMondo model and its related researches(since its publication in 2013),in terms of the core principle of CLUMondo,bibliometrics analysis,applications,and the related improvement.Finally,we discuss the development of the future researches on CLUMondo.
