求翻译：不同林型碳密度由高到低分别为：针叶林（135.44 Mg C•hm-2）＞竹林（129.84 Mg C•hm-2）＞阔叶混交林（129.05 Mg C•hm-2）＞其他阔叶林（128.60 Mg C•hm-2）＞杨树林（119.80 Mg C•hm-2）＞针阔混交林（114.12 Mg C•hm-2）；不同林型各层碳密度对总碳密度的贡献比例均为：土壤层＞乔木层＞凋落物层＞灌草层。是什么意思？

Different carbon density from high to low were: coniferous forest (135.44 mg c • hm-2)> bamboo (129.84 mg c • hm-2)> and broad-leaved mixed forest (129.05 mg c • hm-2) other broad-leaved forest (128.60 mg c • hm-2)> poplars (119.80 mg c • hm-2) coniferous and broadleaved mixed forest (114.1

different forest types in the carbon density from high to low, coniferous forest (135.44 Mg C • HM-2 (129.84 ) > bamboo Mg C • HM - 2) > broadleaved native trees (129.05 Mg C • HM - 2) > Other germinate (128.60 Mg C • HM-2) > Yang trees (119.80 Mg C • HM - 2) > pin wide cataclysmic (1

The different forest carbon density from high to low respectively is: Coniferous forest (135.44 Mg C•hm-2) > bamboo grove (129.84 Mg C•hm-2) > broad-leaf mixed forest (129.05 Mg C•hm-2) > other foliage forests (128.60 Mg C•hm-2) > Yang woods (119.80 Mg C•hm-2) > conifer and broadleaf

Carbon density in different forest types from highest to lowest are: coniferous forest (135.44 Mg c · HM-2) > bamboo (129.84 Mg c · HM-2) > broad-leaf mixed forest (129.05 Mg c · HM-2) > other broad-leaved forest (128.60 Mg c · HM-2) > Yang Shulin (119.80 Mg c · HM-2) > broadleaved (1
