Enhanced Remote Sensing Ecological Index Ecosystem Ecological Environment Quality
2018/5/15
In order to monitor the change of regional ecological environment quality, this paper use MODIS and DMSP / OLS remote sensing data, from the production capacity, external disturbance changes and human...
Predicting the earthwork width and determining the annual growth loss due to forest road construction using artificial neural network and ArcGIS
area of road earthwork hillside slope roadside rock share
2016/8/2
The area of forest destruction as well as the annual growth loss due to road construction before constructing a road was predicted. To do this, road cross sections of 88 points along the 10 km propose...
Determining an optimal path for forest road construction using Dijkstra’s algorithm
selecting path nodes links Nahar Khvoran forest
2016/7/6
From an economic point of view a well-designed road path with the minimum construction cost is an optimal path that can be found using Dijkstra’s algorithm. In this study Dijkstra’s algorithm that con...
Economics of a hydraulic hammer for forest road construction in a mountainous area
hydraulic hammer rock disintegration cut slope productivity costs
2015/3/27
This research deals with productivity and cost of rock disintegration and side casting of materials with the use of a hydraulic hammer mounted on a PC 220 Komatsu crawler excavator, which is used on r...
Assessing the bending strength and modulus of elasticity in bending of exterior foiled plywoods in relation to their construction
plywood density surface density moisture thickness bending strength modulus of elasticity in bending veneer statistical analysis
2015/2/6
The paper summarizes results of an institutional research aimed at assessing the bending strength and modulus of elasticity in bending of exterior foiled combined and all-beech plywoods in relation to...
Current status and prospects of new house construction materials from bamboo
Current status prospects
2014/5/6
Bamboo is widely recognized as one of the most important non-timber forest resources because of the high socio-economic benefits from bamboo based products. It is estimated that there are over 1200 sp...
Relationship between Dwarf-bamboo Growth and Small Rodents on Mt. Ohdaigahara,Central Japan,with Special Reference to Construction of Deer-proof Fences
deer-proof fence dwarf-bamboo Mt.Ohdaigahara sika deer small rodent
2009/8/28
We examined the relationship between dwarf-bamboo growth and small rodents on Mt. Ohdaigahara where the population density of sika deer (Cervus nippon) has been increasing and trunk debarking by the d...
Construction of a Volume Table for Evergreen Broad-leaved Trees with Pipe Model Theory and Relative Stem Curve: A Case Study in the Tokyo University Forest in Chiba,Japan
branch broad-leaved tree pipe model relative stem curve volume table
2009/8/28
In this paper we constructed a volume table for broad-leaved trees including a stem and branches using a relative stem curve, provided that the trees are subject to the pipe model theory. First we mea...
Application of the Local Yield Table Construction System to a Timber Self-Supply Production Strategy in Ise Shrine Forest with Special Focus on the Shikinen Sengu Ceremony
growth model Ise Shrine large-timber production Local Yield Table Construction System Shikinen Sengu Ceremony
2009/8/24
The Forestry Department of the Ise Shrine is planning to produce timbers in the Ise Shrine Forest to rebuild the temples for the Shikinen Sengu Ceremony held every 20 years. Thus, this study proposes ...
Construction of Crown and Definite Diameter Height Control Diagram of Young Cryptomeria japonica Stand
clear length crown control Cryptomeria japonica definite diameter height stand density
2009/8/21
A control diagram of crown and stem form was attempted to construct based on the analysis of relationships among several stand characteristics. The data was collected from 32 young even-aged stands of...
Recent developments in forest traffic way construction in Slovenia

2009/2/7
After a decade of regression in forest engineering a distinct increase in skidding trail construction and intentional revival of road constructions in state forests have occurred since the year 2000...
Seed rain traps for forest lands：Considerations for trap construction and study design
exotic plant species invasionL seed dispersal seed rain trap sample design
2009/1/9
Seed rain studies provide valuable information for forest researchers monitoring exotic species invasions. Plant species move through forests primarily as seeds, and this dispersal is critical to futu...
林木遗传连锁图谱构建研究进展与发展方向Research Progress in Forest Tree Genetic Linkage Map Construction and Its Future Prospects
遗传连锁图谱 QTL定位 表达序列标签多态性（ESTP） 比较作图
2008/1/16
摘要本文就目前国内外林木连锁遗传图谱领域的研究进展进行了综述，指出了该领域研究中存在的主要问题，即一方面是作图个体的数量有限，另一方面是采用的标记以随机标记为主，导致了建成的图谱以及利用图谱获得的数量性状基因位点（QTLs）信息具有杂交组合特异性，造成了QTLs的可信度和在林木遗传改良以及标记辅助选择中的实用性降低等现象。针对存在的问题，讨论了根据林木生物学特点选择合适遗传标记的意义，指出进行林木...
