In, this study, we analysed the effects of thinning on stand structure and carbon stocks for a mixed conifer broadleaf natural secondary forests in Small Khingan Mountains, China. Stand were assessed trees from unthinned control (CK), lightly thinned (LT), moderately (MT) heavily (HT) treatments. Results showed that heavier thinning, larger crown area became. Under MT treatment, tended to be ev...

Black locust (Robinia pseudoacacia L.) is one of the most widespread tree species introduced into Europe and also Hungary. It covers 24% total Hungarian forest area, providing 25% annual timber output country. Due to demands consumers, new cultivars are be produced by means improvement techniques practical forestry use. Mono- multiclonal were developed, then variety comparison trials cultivatio...

Structural health monitoring of cracked structures is one of beloved subject of researchers recently. Consider of crack behavior in the water and energy pipeline is important because of environmental problems. In this paper consider of crack parameters in the underwater pipe subjected to mechanical transient load is investigated. For this purpose, three- dimensional parametric model of cracked ...

Forest productivity (increment of above-ground biomass) is determined by biodiversity but also stand structure attributes. However, the relative strengths these drivers in determining remain controversial subtropical forests. In this study, we analyzed a tree growth data from 500 plots with 20 ha mature forest eastern China. We used spatial simultaneous autoregressive error models to examine ef...

An understanding of the interactions between climate change and forest structure on tree growth are needed for decision making in forest conservation and management. In this paper, we investigated the relative contribution of tree features and stand structure on Atlas cedar (Cedrus atlantica) radial growth in forests that have experienced heavy grazing and logging in the past. Dendrochronologic...
