摘　　要：According to the data of pollen analysis,the vegetation varied greatly between the southand the north of the Kurdun Mountains during the Pliocene.To the south of the Kunlun Mountains,includ-ing their south flank,there was distribution of needle and broad-leaf mixed forest that contained tropical andsubtropical compositions,while to the north of the Kunlun Mountains,including their north flank,therewas distribution of temperate deciduous broad-leaf forest and steppe.In both areas mentioned above,therewere scattered middle Asian arid plants of a lush growth in the late Pliocene.In the Pliocene,the Pamir-Kunlun Ranges acted as the division line of the southern and northern types of plants.Then,with the risingof these mountains,inciuding Pamir,Kunlun and Himalaya,this division line had been moving,until itreached the Xindukushi-Himalaya Mountains at present.According to the data of pollen analysis,the vegetation varied greatly between the south and the north of the Kurdun Mountains during the Pliocene.To the south of the Kunlun Mountains,includ- ing their south flank,there was distribution of needle and broad-leaf mixed forest that contained tropical and subtropical compositions,while to the north of the Kunlun Mountains,including their north flank,there was distribution of temperate deciduous broad-leaf forest and steppe.In both areas mentioned above,there were scattered middle Asian arid plants of a lush growth in the late Pliocene.In the Pliocene,the Pamir- Kunlun Ranges acted as the division line of the southern and northern types of plants.Then,with the rising of these mountains,inciuding Pamir,Kunlun and Himalaya,this division line had been moving,until it reached the Xindukushi-Himalaya Mountains at present.
