THE DIFFERENTIATIONS IN WINTER CLIMATES OF THE ESTERN PART WESTERN PART AND OF THE TROPICAL CHINA AND THEIR IMPACTS ON THE INTRODUCTIOIN OF RUBBER TREE
Forest stand growth is impacted by thinning intensity, thinning methods, standstructure, terrain conditions, timber ages and climates in forest areas. The stand growthprocess is random changed and the growth models is different under different factors.
Thousand kernels per weight of the seeds collected in the next spring is 54.95g less than those counterparts of seeds collected in autumn which is 61.62g and number of wormy seeds per hundred is 13.6 more than autumn which is 8.7. The factors that influencing dispersal of F mandshurica seeds are density, height, distribution, composition of surrounding trees, topography, shape of maternal trees crown and climates factors etc.
According to the factors such as, climates,soil and forest types,the forest ofHenan Province was divided into two forest vegetation regions and eight forest ecosys-tems.
The climatic--ecological effect of poplar--seabuckthorn mixed forest in the arid, windy and sandy district of north--western Liaoning and the mathematical model for mixing
Using the fatal forest fire data obtained from 15 to 18 April 2003 in Diebu and meteorological data obtained from May 2002 to April 2003,the Meteorological Conditions of the fire are analyzed,and EOS/MODIS data are used to analyze the soil humidity and the degree of fire.
Our study indicates that the model can be applied to study the interaction between land surface processes and atmospheric boundary layers over various underlying surfaces and their regional climate effects.
It is important to be able to monitor and estimate forest biomass and production, regional carbon storage, and global climate change impacts on these important vegetation types.
The specimens plated were tested by exposure for 14-20 years at coastal corrosion stations in cold (Murmansk), moderately humid (Vladivostok), and humid subtropical (Batumi) climates.
At present, it is being revised by using data from new programs of atmospheric tests carried out in cold, temperate, subtropical, and tropical climates.
The K0 and k factors in the model were determined according to the corrosion of Ct3, copper, brass, zinc, aluminum, Δ16 alloy, and AMц alloy in the zones of cold, moderate, subtropical, and tropical climates.
Six Italian clones, P. deltoides cv. I-63, I-69, eramerican hybrids I-72, I-214, I-45 and P. nigra cv. blanc garrone introduced into Jiangsu Province in 1972 recorded a rapid growth, with I 03, I-69 and I-72 being the most outstanding. But, according to our experience, different varieties require different growing conditions: P. deltoides I-63, I-69 and P. euramerican I-72 are best-adapted to warmer regions, while the euramerican hybrids I-214, I-45 and P. nigra blanc de garrone are more adapted to the temp...
A detailed comparison of climatic characteristics between the mediterraneanregion,the olive-planting area,and the Chen-gu county was made in this article.Heat, water and light conditions were emphasized. Both the mediterranean region and the Chen - gu county belong to the subtropi-cal climate,the only difference is that,the former is dry in summer,while thelatter, dry in winter. In summer, during the fruiting season,Chen - gu county is rainy,and cloudy,the sunshine - hour totaled only 727 from June through ...
Monsoon indices used in this paper are defined as:1. Angle of deviation of prevailing wind in January and July≥120。2. Average frequencies of the directions of the prevailing wind in thesame months = 40%or close to it. With indices so defined as criteria, the monsoon districts in china willinclude the following provinces, munipalities, or autonomous regions, Li-aoning, Jilin, Heilongjiang, Shanxi, Hebei, Shandong, Henan, Jiangsu, Zhejiang,Fujian, Guangdong, Guangxi, Guizhou, Yunnan, Hubei, Hunan, Anhui,Jiang...
