Tree growth equations which were models for describing each of trees growth factors changing with ages have been used widely for evaluating tree height,volume,and so on. This study selected 7 typical tree growth equations to simulate tree growth process under different forestland sites for Pinus tabilaeformis and Robinia pseudoacacia plantations,respectively,which were based on forest inventory data and sub-compartments. Results showed that all 7 equations could simulate tree growth process,in which Korf and Logistic equations were better than others. Parameters a,b and c were effected significantly by forestland site. In addition,these equations were tested and could be used for predicting tree growth accurately. Then,both trees growth of Pinus tabilaeformis and Robinia pseudoacacia were simulated and it implied that Pinus tabilaeformis grew well under schattenseite and Robinia pseudoacacia grew well in this place with no sunny slope. For the western Liaoning (north) area of site quality evaluation and plantation of reasonable management,this provides a scientific reference.

Continuous development of urban road traffic system requires higher standards of road ecological environment. Ecological benefits of roadside trees are getting more attention. Carbon sequestration is a measurement of roadside trees’ ecological benefits. The traditional method of estimating carbon sequestration is costly and inefficient. In order to solve above problems,a method using vehicle-borne laser point cloud data to estimate the carbon sequestration of roadside trees is proposed in this paper. The method can calculate the geometric parameters of a roadside tree,including tree height,crown diameter,diameter at breast height,by processing and analyzing point cloud data of an individual tree. Combining the calculated geometric parameters and an appropriate carbon sequestration calculation model,the estimated single tree’s carbon sequestration can be calculated. The proposed method can help enlarge application range of vehicle-borne laser point cloud data,improve the efficiency of estimating carbon sequestration,construct urban ecological environment and manage landscape.
