摘　　要：The climate of the North-Central China during the Early Holocene is still debated,particularly with regard to precipitation,despite various paleoclimate records based on multi proxies and models(Chen et al.,2015;Liu J B et al.,2015;Liu Z Y et al.,2014).The temperature pattern is also uncertain because of a lack of temperature records for north-central China.Pollen sequences are still the most abundant paleo-environmental record particularly for north-central China and have the potential to explore the past precipitation and temperature changes,because both precipitation and temperature are essential for plant growth,and the sensitivity to climatic variables varies among different plants(Liang et al.,2020).Quantitative climate reconstructions based on the modern pollen-climate relationship have been widely generated for east Asia,and the results used to explore the spatial-temporal patterns and mechanisms of past climate changes(Chen et al.,2020,2015;Herzschuh et al.,2019).
