“…In general, different tree species play an important role in biogeochemical regulation of ecosystems through stabilization of SOC (Chen et al 2003), a vital parameter in the formation and maintaining of soil structure, moisture and fertility (Macedo et al 2008;Craswell and Lefroy 2001), that is found in this research as like. Also, Arai and Tokuchi (2010) in their research regarding the effect of coniferous species on the soil in terms of OM accumulation in Scotland reported that Cryptomeria japonica had higher OM content compared to natural forests, conforming to results obtained for some coniferous species in the viewpoint of greater storage of organic carbon and to some extent consistent with the results of this research. Accordingly, it is possible that Coniferous stands absorb more C compared to hardwood stands.…”

Rafeie Jahed R, Hosseini SM, Kooch Y. 2014. The effect of natural and planted forest stands on soil fertility in the Hyrcanian region, . In the present work, we studied the effect of natural and planted forest stands on soil fertility in the Hyrcanian region of northern Iran. Natural forest stands (including Acer velutinum Bioss., Zelkova carpinifolia (Pall), Parrotia persica (DC.) C.A.Mey, Quercus castaneifolia C.A. Mey., Carpinus betulus L, Mixed planted stand (including Acer velutinum, Ulmus carpinifolia G. Suckow Quercus castaneifolia C.A. Mey, Carpinus betulus L., Tilia begonifolia Scop. subsp. caucasia (Rupr.) Loria; maple (Acer velutinum Bioss) plantation, pine (Pinus taeda L.) plantation and also clear-cut region (control) were considered in this research. Soil samples were collected at two different depths, i.e., 0-15 and 15-30 cm, and characterized with respect to organic carbon (C), total nitrogen (N), available nutrient elements (P, K, Ca and Mg); pH and soil texture. The results showed that the highest amount of total N was found in mixed plantation. The highest amount of available P was detected in maple plantation and pine plantation had the highest available K and organic C than other treatments. The highest and the lowest available Ca and Mg were found in natural forest and control area, respectively. In addition, it was observed that nutrients accumulate in upper layers of the soil. Hardwood stands have been more successful than the conifers stands, so this should be considered in the sustainable management of forests.

“…A global meta-analysis showed that soil organic C content is affected by vegetation type in arid and semiarid regions [43], and the average soil organic C contents of mixed-plantation and herb plots were lower than those of other plots. Thus, with different accumulation rates of soil organic C [43] and with different properties in litter and soil [44], under the influence of the soil aggregate structure [45], the C source provided was reduced, which significantly influenced soil C sequestration and nutrient cycling. Changes in the availability of soil nutrients influence extracellular enzyme activities and stoichiometry [12,46], thereby influencing the limitations of microbial metabolism.…”

Soil extracellular enzymes are considered key components in ecosystem carbon and nutrient cycling, and analysing their stoichiometry is an effective way to reveal the resource limitations on soil microbial metabolism. In this study, the soil and litter of Quercus acutissima plots, Pinus thunbergii plots, Quercus acutissima–Pinus thunbergii mixed-plantation plots, herb plots, and shrub plots in the state-owned Dawa Forest Farm in the Yimeng Mountain area were studied. The total carbon (C), nitrogen (N), and phosphorus (P) contents of litter and the physical and chemical properties of soil were analyzed, along with the activities of four extracellular enzymes related to the soil C, N, and P cycle: β-1,4-glucosidase (BG), β-1,4-N-acetylglucosaminidase (NAG), L-leucine aminopeptidase (LAP), and acid phosphatase (AP). The extracellular enzyme stoichiometric model was used to study and compare the metabolic limitations of soil microorganisms in different plots, and the driving factors of microbial metabolic limitations were explored by redundancy and linear regression analyses. The results showed that the values of BG/(NAG + LAP) were all higher than 1, the values of (NAG + LAP)/AP all lower than 1, and the vector angles of the five plots all greater than 45°, which indicated that the soil microorganisms were relatively limited by C and P. Redundancy and linear regression analysis revealed that soil physical properties (e.g., soil moisture) and litter total C make greater contributions to soil extracellular enzymes and stoichiometry than the other investigated soil parameters, whereas soil chemical properties (e.g., soil organic C and available P) predominantly controlled vector properties. Therefore, microbial metabolism limitations are greatly regulated by soil physical and chemical properties and litter total C and N. Compared with the forest plots, the soil microbial C (1.67) and P (61.07°) limitations of herb plots were relatively higher, which means that the soil microbial communities of forest plots are more stable than those of herb plots in the Yimeng Mountain area. Forest plots were more conducive than other plots to the improvement of soil microbial ecology in this area. This study could be important for illuminating soil microbial metabolism and revealing soil nutrient cycling in the Yimeng Mountain area ecosystem of China.

“…Identifying tree crown areas via remote sensing approaches is an intensive area of interest in both forest ecosystem research and forest management (Trichon 2001;Skurikhin et al 2013;Wu and Peng 2010;Ardila et al 2012;Hosoi et al 2012;Li et al 2009;Pouliot and King 2005;Pouliot et al 2002). The identification of crown areas plays an important role in regional and global studies on temperature change (Wang, Yan, and Wang 2015), evapotranspiration (Chen et al 2015;Trabucco et al 2008) and soil organic carbon accumulation (Arai and Tokuchi 2010;Li, Niu, and Luo 2012), among other topics.…”

In this letter, we propose an identification method of tree crown areas for imagery captured by a near-infrared camera on board an unmanned aerial vehicle platform over an undulating Eucalyptus planting area in Guangdong Province, China. The method extracts crown areas by applying mathematical morphology, unsupervised segmentation based on J-value segmentation, local spatial statistics, and Iterative Self-Organizing Data Analysis Technique Algorithm. Two morphology filters and four segmentation scales were compared between densely and sparsely planted plots as well as sunlit and shaded plots. The opening operation by the window size of 9×9 pixel and segmentation by the seed area sized 65×65 pixel achieved the best performance with overall accuracy of 91%, 93%, 89% and 91% in densely sunlit, sparsely sunlit, densely shaded and sparsely shaded plots.
