Abstract

Abstract: The topsoil contents,densities and storage of soil organic carbon(SOC) and total nitrogen(TN) of four different vegetation restoration patterns,i.e.,Prunus salicina,Juglans cathayensis,Punica granatum and Passiflora caerulea were studied in rocky desertification region in Guizhou Province.The results showed that the contents of SOC under four different vegetation restoration patterns were in the order of Prunus salicina＞Passiflora caerulea＞Juglans cathayensis＞Punica granatum, while the contents of TN did not differ much.SOC and TN contents and densities in the 0~10 cm soil layer were higer in the 10~20 cm soil layer in each of the four vegetation restoration patterns.SOC storage in the topsoil layer was the highest(54.31t/hm²) in Prunus salicina,and TN storage in the topsoil layer was the highest(6.21t/hm²) in Passiflora caerulea.Both SOC and TN storage were the lowest in Punica granatum,with 49.77t/hm² and 5.66t/hm² respectively.Prunus salicina and Passiflora caerulea were both comparative better vegetation restoration patterns in the process of vegetation restoration and reconstruction in the rocky desertification region of Guizhou Province.

Key words: vegetation restoration patterns, soil carbon and nitrogen content, soil carbon and nitrogen storage, rocky desertification region, Guizhou Province
