Abstract

In order to integrate increasing carbon sequestration of plants into vegetation restoration and reconstruction project in Guizhou karst area, the carbon storage, spatial distribution characteristics and carbon sequestration benefits of five kinds of disposition modes were studied in Karst Peak-Cluster Depression Areas. The result showed that: Disposition model of each vegetation carbon storage and increment is characterized by vine layer > shrub layer > tree layer > herb layer. In the vegetation layer vine layer and the shrub layer carbon increment of vegetation carbon density has no significant difference, respectively accounting for 56.06%, 48.31%, which are in the dominant, but far higher than other vegetation layer. In addition, the carbon increment of different mode of herb layer and soil layer has small differences, and carbon storage appeared lower than that of control. Based on five disposition model of carbon increment and economic benefit analysis, we concluded that different disposition model in the 10 and 20 years later, both carbon increment and economic benefit are characterized by Mode 3(Zenia insignis Forest) > Mode 1(Ligustrum lucidum Forest) >Mode 5(Broussonetia papyrifera Forest) > Mode 4(Zenia insignis Forest) > Mode 2(Sophora japonica Forest). The trends are the same, which fully prove and illustrate the accuracy of estimation model. The disposition model 3 of Zenia insignis forest has the highest economic value of respectively 16823 USD/hm2 ten year later, 32735 USD/hm2 after twenty Years later. This research will provide scientific basis and practical methods for the comprehensive treatment of rocky desertification in Karst to obtain maximum economic benefit of carbon fixation.
