摘要
基于河南省2000、2020 年土地利用数据以及社会、气象数据,采用 PLUS 模型模拟河南省2040 年不同发展情景下的土地利用及有机碳分布格局.模拟结果显示,河南省 2040 年 3 种情景下的有机碳储量分别为1206.98×106 t(自然发展情景)、1211.98×106 t(耕地保护情景)、1 212.20×106 t(生态保护情景),表明林地数量的提高对河南省有机碳储量的提升具有积极作用.河南省有机碳呈明显的区域性分布特征,总体表现为西部较高,南部次之,东部和北部表现出一定的中等水平分布特征.
Abstract
Based on the land use data of Henan Province in 2000 and 2020,as well as social and mete-orological data,the land use and organic carbon distribution patterns of Henan Province in 2040 under different development scenarios were simulated.The simulation results showed that the organic carbon stocks in Henan Province in 2040 under three development scenarios would reach 1206.98×106 t(natu-ral development scenario),1 211.98×106 t(cropland protection scenario)and 1 212.20×106 t(eco-logical protection scenario),indicating that the increase in the amount of forest land in Henan Province had a positive effect on the enhancement of organic carbon stocks in Henan Province.The organic carbon in Henan Province showed obvious regional distribution characteristics,generally showing higher in the west,followed by the south,while the east and north showed some middle level distribution characteristics.
