Above-ground biomass (AGB) plays a pivotal role in assessing a forest’s resource dynamics, ecological value, carbon storage, and climate change effects. The traditional methods of AGB measurement are destructive, time consuming and laborious, and an efficient, relatively accurate and non-destructive AGB measurement method will provide an effective supplement for biomass calculation. Based on the real biophysical and morphological structures of trees, this paper adopted a non-destructive method based on terrestrial laser scanning (TLS) point cloud data to estimate the AGBs of multiple common tree species in boreal forests of China, and the effects of differences in bark roughness and trunk curvature on the estimation of the diameter at breast height (DBH) from TLS data were quantitatively analyzed. We optimized the quantitative structure model (QSM) algorithm based on 100 trees of multiple tree species, and then used it to estimate the volume of trees directly from the tree model reconstructed from point cloud data, and to calculate the AGBs of trees by using specific basic wood density values. Our results showed that the total DBH and tree height from the TLS data showed a good consistency with the measured data, since the bias, root mean square error (RMSE) and determination coefficient (R2) of the total DBH were −0.8 cm, 1.2 cm and 0.97, respectively. At the same time, the bias, RMSE and determination coefficient of the tree height were −0.4 m, 1.3 m and 0.90, respectively. The differences of bark roughness and trunk curvature had a small effect on DBH estimation from point cloud data. The AGB estimates from the TLS data showed strong agreement with the reference values, with the RMSE, coefficient of variation of root mean square error (CV(RMSE)), and concordance correlation coefficient (CCC) values of 17.4 kg, 13.6% and 0.97, respectively, indicating that this non-destructive method can accurately estimate tree AGBs and effectively calibrate new allometric biomass models. We believe that the results of this study will benefit forest managers in formulating management measures and accurately calculating the economic and ecological benefits of forests, and should promote the use of non-destructive methods to measure AGB of trees in China.

This study aims to estimate carbon stored in above ground at the Mempawah Mangrove Park (MMP) area of Mempawah District, the data used were mangrove planted in 2013. Full Enumeration was used in this study while collecting the data applied non destructive sampling method for the tree, its was a diameter of ≥ 5 cm. Based on the results of measurements and observations in the field directly, it had 63 of the total number of line which were done by all the areas of Mempawah Mangrove Park in Mempawah District. The result of this study reveals which has 2 (two) kinds of mangrove. They are Avicennia marina dan Rhizopora stylosa. Avicennia marina is kinds of mangrove that dominate with the total number of 35 individuals based on the tree level and 1404 individuals relating the stake level. Then, Rhizopora stylosa gets the stake level for two individuals so that the stand density is 379.21 /ha. The value of biomass in the MMP area is 7.16 tons C / ha and the carbon value in the MMP area is 3.37 tons C / ha.Keywords: Above Ground Biomass, Carbon, Mangrove ForestsPenelitian ini bertujuan untuk menduga karbon tersimpan di atas permukaan tanah di kawasan Mempawah Mangrove Park (MMP) Kabupaten Mempawah, data yang digunakan yaitu data yang ditanam pada tahun 2013. Metode yang digunakan pada penelitian ini yaitu pengamatan secara menyeluruh (full enumeration), sedangkan untuk mengumpulkan data di lapangan menggunakan metode non destructive sampling (pengukuran tanpa melakukan pemanenan) pada pohon yang berdiameter > 5 cm. Berdasarkan hasil dari pengukuran dan pengamatan secara langsung di lapangan dengan jumlah jalur sebanyak 63 yang dilakukan pada seluruh kawasan MMP. Hasil penelitian menunjukkan bahwa terdapat dua jenis mangrove yaitu jenis Avicennia mariana dan Rhizopora stylosa yang mendominasi pada kawasan MMP, dimana A. Mariana merupakan jenis yang mendominasi dengan jumlah 35 individu pada tingkat pohon dan 1.404 individu pada tingkat pancang, sedangkan untuk jenis R. Stylosa hanya terdapat pada tingkat pancang dengan jumlah 2 individu sehingga didapatlah kerapatan tegakan sebesar 379,21 ind/Ha. Nilai biomassa pada kawasan MMP sebesar 7,16 ton C/Ha dan nilai karbon pada kawasan MMP sebesar 3,37 ton C/Ha.Kata kunci : mangrove, Karbon, karbon tersimpan

The use of 3D scanning systems for acquiring and analyzing the external shape features of arbitrary objects has different applications in different cultural, scientific, and technological fields. In this work, 3D laser scanning techniques are used, for the first time, to our knowledge, as a novel and non-destructive application for the morphological study of meteorite impact rocks. The subject of the study was a rock displaying impact textures and associated with the Karikkoselkä impact crater (Finland) (Lehtinen et al. 1996). This methodology permitted: (1) a computerized three-dimensional modelling to be carried out on the bulk impact-related rock; (2) other more specific characterizations to be performed, such as detailed topographic studies of its surface impact features; (3) some physical properties of the rock to be determined (volume); (4) the shatter cone impact texture to be completed with a realistic estimation of its convergence angle; and (5) a broad demonstration of the significance and effectiveness of 3D laser scanning techniques as a complementary tool for the study of this type of meteoritic impact-related rocks.
