RESEARCH ON THE TECHNIQUES FOR CUTTING OF CINNAMOMUM BALANSAE Số 2 - Trang 087-096 - 2017
Tran Ngoc Hai, Dang Huu Nghi, Le Dinh Phuong, Tong Van Hoang
Cinnamomum balansae is an endemic, rare species of tree in Vietnam, was rated
level EN by IUCN, VU by the Vietnam Red Book – 2007 and classified as group IIA
by Decree 32/2006/NĐ-CP. Besides its natural regeneration capacity is very
limited so conservation and development for this species are facing a big
challenge of seedling shortages. Therefore, study of breeding Cinnamomum

ABOVE AND BELOW GROUND BIOMASS OF ACACIA HYBRID INDIVIDUAL TREE AT LA NGA FORESTRY COMPANY LIMITED, DONG NAI PROVINCE Số 12 - Trang 070-080 - 2021
Nguyen Thi Ha
The study was conducted to determine the above and below ground biomass of
Acacia hybrid (Acacia auriculiformis*Acacia mangium) of different diameter
classes at La Nga Forestry Company Limited in Dong Nai. A typical standard tree
survey method was used to measure fresh biomass, the study cut down 45 trees of
different ages and diameters for measuring the fresh biomass with 4 parts
including trunk,... hiện toàn bộ

Mapping small burned areas using high spatial resolution planetscope imagery: a case study of the wildfire in Da Lat city - 2023
Pham Duc Binh
This study employed high spatial resolution PlanetScope imagery at 3 m
resolution for mapping burned area and burn severity resulting from a wildfire
that occurred from April 7-9, 2023 in the highland of Vietnam. The wildfire took
place in a protection forest near the Prenn pass in Da Lat city, Lam Dong
province, Vietnam. Pre- and post-fire Normalized Difference Vegetation Index
(NDVI) maps were g... hiện toàn bộ

Carbon mineralization potential and nutrient dynamics in soils under vegetation types and soil depths at Luot mountain Tập 9 Số 2 - Trang 032-042 - 2024
Nguyen Thi Bich Phuong, Nguyen Thi Bich Hoa, Tran Thi Hang, Bui Manh Hung, Pervez Khan
Soil mineralization is a crucial soil process that improves soil physical
properties, enhances carbon sequestration, and provides essential minerals and
available nutrients for plant growth. This study was conducted at five
vegetation types and soil depths at Luot mountain area, located in VNUF campus,
Hanoi city. Samples were incubated in the dark at 25°C and measured at intervals
of 1, 2, 5, 10,... hiện toàn bộ

Models for biomass expansion factor of acacia hybrid (A. auriculiformis* A. mangium) plantations in the Southern region, Vietnam Tập 8 Số 2 - Trang 138-146 - 2023
Tran Thi Ngoan, Nguyen Tan Chung, Nguyen Thi Ha, Dao Thi Thuy Duong, Nguyen Tuan Vu
Acacia hybrid is one of the favorably fast-growing species which is bring to
potential benefits of agro-ecological and socio-economic sectors in Vietnam. The
main objective of this study was to develop well-fitted models for estimating
biomass expansion factor (BEF) for Acacia hybrid plantations. Fifty-four samples
of Acacia hybrid trees from 2 to 10 years of age were collected from Acacia
hybrid ... hiện toàn bộ

Diversity and ecological role of Dipterocarpus obtusifolius Teijsm. ex Miq. in Nui Cau - Dau Tieng protection forest, Binh Duong province Tập 9 Số 1 - Trang 062-072 - 2024
Nguyen Thi Ha, Nguyen Thi Hanh, Nguyen Thi Hoa, Nguyen Van Lam, Phan Thanh Trong, Pham Chi Thinh, Nguyen Van Hop
Studying the diversity and ecological role of dominant species provides an
important foundation for understanding the influence of dominant species on the
diversity and biomass production capacity of plant communities. This study was
conducted at the Nui Cau - Dau Tieng Protection Forest Management Board, Binh
Duong province, to understand the diversity and ecological role of Dipterocarpus
obtusif... hiện toàn bộ
