利用CLUMondo模型,探究福建省在生态预期目标(生态效益最大化且森林蓄积量不低于目标值)、经济预期目标(满足经济发展目标且林地面积不减少)以及常规协调预期目标(生态、经济目标均按现状稳定发展)下土地利用的优化配置.研究表明:1)CLUMondo模型适用于福建省的土地利用/覆被变化模拟;2)福建省若要在未来尽可能保持现有林地面积的情况下实现经济发展,需要进一步提高森林管理水平,完善森林生态效益补偿制度;3)福建省应在未来优化城镇规划开发格局,加强城市、生态等主题功能区的集约高效发展,保证在经济发展的情况下生态环境得到可持续发展.本文的研究为促进福建省的经济发展、助力我国碳达峰目标的实现提供了参考.
Trade-off impact of carbon-peak target of forest volume and economic development goals on land use/land cover in Fujian
In the context of global advocacy of sustainable development,China is striving to reach a peak in CO2 emission before 2030.Land use change is closely related to carbon emissions and forest stock volume.Thus,it is necessary to balance and optimize land use under different development scenarios before carbon emission peaks.To achieve peaking in carbon emissions,Fujian is crucial because forest coverage rate there is the highest in all of China.But Fujian is also necessary for China's economic growth.Future land use changes in Fujian are affected by a trade-off between carbon-peaking actions and economic development.Here CLUMondo model is used to explore optimal land use allocation under 3 scenarios:1)ecological target scenario(maximizing ecological benefits,the forest stock volume is not lower than the target value),2)economic target scenario(satisfying the land use status in 2030 under the economic development target,the forest area is not degraded)and 3)conventional coordinated target scenario(ecological and economic goals are developed steadily according to the current situation).The CLUMondo model is found suitable for land use/land cover change simulation in Fujian province.To achieve economic development while maintaining existing forest area as much as possible in the future,Fujian province needs to improve forest management level,forest quality,forest ecological benefit compensation system.Fujian province should optimize urban development pattern and strengthen intensive development of urban,ecological functional areas.
