随着全球气候变化研究的深入,以及多种气候系统敏感性模拟,人们越来越认识到人类活动可能是驱动历史时期气候变化的重要因素之一.因此,自21世纪开始,土地覆被变化(LandCover Change)成为全球气候变化研究和气候模拟的核心和热点.而建立花粉—植被—土地利用的关系可能是定量检测人类活动对自然环境影响的有效途径之一.为此,在石家庄西部太行山区选择了2个小流域,利用拦水坝汇水流域的土地利用状况和花粉组合特征,建立了小流域花粉植被土地利用的定量关系.流域内花粉组合既有自然植被成分,也有农作物花粉类型,较好地反映了流域内花粉—植被—土地利用的关系;随着海拔高度降低,农田面积不断增加,人类活动强度逐渐增大,谷物及蔬菜类花粉也逐渐增多,花粉百分比与土地利用回归分析表明,谷物和蔬菜类花粉百分比与农田面积呈线性正相关,对人类活动具有明显的指示意义.“,”With the progress of study on global climate change and the sensitivity simulation of various climate systems,human activities might be one of important factors driving climate change in historical periods.Therefore,since the beginning of this century,Land Cover Change has become the currently hot topic of global change research and climate simulation.The establishment of pollen-vegetation-land use relationship may be one of the effective ways to obtain quantitative estimates of human impact on natural environment.Therefore,in the Taihang Mountains,two small watersheds were selected to detect the relationships quantitatively among pollen,vegetation and land-use of small watershed by using pollen data.There are natural vegetation components and crop pollen types in pollen assemblages,which well reflect the relationships among pollen,vegetation and land-use in small watershed.As altitude decreases,the area of farmland,the intensity of human activities and the cereal,vegetable pollen percentages increases.The regression analysis of pollen percentages and land-use indicate that a linear positive relationship exists between the percentages of cereals,vegetables pollens and the area of farmland,which has a significance for human activities.
