Spatial variation of altitudinal belts as dividing index between warm temperate and subtropical zones in the Qinling-Daba Mountains 总被引:1,自引:0,他引:1
To determine the dividing index between warm temperate and subtropical zones based on the spectra of altitudinal belts,this paper collected 33 spectra of altitudinal belts in the Qinling-Daba Mountains from published literatures and then analyzed the structures and the spatial patterns from south to north,from west to east and based on exposure directions.The results show that:1)From south to north,the basal belt gradually changes from subtropical evergreen broadleaf forest to warm temperate deciduous broadleaf forest;the spectra of altitudinal belts change from complex to simple;the dominant belt changes from montane broadleaf-conifer mixed forest and evergreen-deciduous broadleaf mixed forest to deciduous broadleaf forest.2)From west to east,the structures of the altitudinal belt spectra show complexity in the east and west but simplicity in the middle section;the upper limits of both the evergreen-deciduous broadleaf mixed forest belt and montane deciduous broadleaf forest belt present a quadratic curve distribution pattern in the longitudinal direction.However,the upper limit of the montane broadleaf-conifer mixed forest belt exhibits a nearly linear decrease in the west-east direction.3)Both the north and south slopes in the Qinling Mountains have the similar basal belt,whereas it varies greatly between the north and south slopes in the Daba Mountains.Comparably,dominant belts are very similar in the Qinling Mountains and the north slope of the Daba Mountains,but the south slope of the Daba Mountains has its own unique dominant belt:evergreen-deciduous broadleaf mixed forest.This implies that the Daba Mountains are more appropriate than the Qinling Mountains to act as the boundary between subtropical and warm-temperate zones in central China. 相似文献

正春风吹来,喜报频传。近日,在郑州市二七区2017年度工作总结表彰大会上,二七区国土资源局接连获得"工作考核优秀单位""项目建设奋力推进年行动先进单位""新型城镇化建设工作先进单位"3项荣誉称号。获得诸多荣誉,秘诀何在?"在我看来,关键在于牵住了党建工作这个‘牛鼻子’。近年来,我们以党建工作为抓手,采取有效措施,让基层党组织不断动起来、活起来,让党员干部的模范带头作用充分发挥出来,各项工作稳步有序开展。" 相似文献
