通过定性的方法对云南省老君山姊妹湖地区的化石孢粉进行了研究，在年代数据的基础上并结合周围地区表土花粉的分布特征，重建了该区小冰期以来的植被变化的历史．孢粉组合结果显示，老君山姊妹湖地区的植被在小冰期以来主要以冷杉林、杜鹃灌丛及高山栎组成的亚高山植被为主，但由于所受到的季风影响强度不同，植被类型随着气候的不同发生了较大的变化．同时，禾本科、蒿属及伴人植物蓓草属等花粉的逐渐增多，也说明了该流域的植被受到人类活动的影响逐渐增强．

On the basis of fossil pollen analysis in the sediments from Lake Zimei in Mount Laojun and in combination with chronological data and surface pollen in the surrounding regions, the paleovegetation in this region since LIA was reconstructed. The combined pollen data shows that the vegetation is mostly dominated by subalpine types of Abies, Ericaceae and Quercus since LIA, but the constructive and dominant species changes a lot owing to the influence of southwest monsoon. In addition, the gradually increasing percentage of Gramineae, Artemisia and Humulus pollen, also shows that human activities have played an increasingly bigger role in this basin that leads to the change of the primitive forest.
