Forest fire is one of the most important ecological factors in the forest ecosystem. The Daxinanling forest region has not only the largest forest areas, but also the biggest forest fire burned area i...
Tree-ring width chronologies were developed for Larix gmelini of main forest types in Daxinganling mountains, and by correlation analysis and response function analysis illustrate difference empact of...
In This paper, the miscellaneous tree low-quality forest and Oak low-quality forest in the Greater Hinggan Mountains region were transformed inductively by planting Siberian Korean pine, Mongolica, an...
Using the Landsat 5 TM images in 2002 as source data,the paper constructed individual tree biomass models of seven principal species based on the data from field surveying and fixed Plots in Tahe and ...
We investigated the summertime formation of secondary organic aerosols (SOA) via the oxidation of isoprene, α/β- pinene and β-caryophyllene in a Quercus crispula and Picea glehnii mast mixed forest l...
This paper proposes a distributed intelligent system for forest fire detection based on integration of information from several distributed sensors. An automatic fire detection system with ultraviolet...
Forest fire is one of the most important ecological factors in the forest ecosystem. The Great Xing’an Mountain region has not only the largest forest areas, but also the biggest forest fire burned ar...
The forest biomass (which is referred to the arbor aboveground biomass in this research) is one of the most primary factors to determine the forest ecosystem carbon storages. There are many kinds of e...
The spatial pattern of forest fire locations is of interest for fire occurrence prediction. A spatial statistical analysis of lightning-caused fires in the province of Heilongjiang, China, between 197...
This paper, based on the forest map of Mao’er Mountain in 1983 and forest inventory sub-compartment database of Mao’er Mountain in 2004, and with the support of geographical information system (GIS), ...
Palynological correlation is made between Atokan and lower Desmoinesian strata in the Illinois basin and the Forest City basin in eastern Kansas. Spore data from previous studies of coals in the Illin...
Biotite and amphibole containing up to 4.6 and 5.1 wt%Cl,respectively, are found in gneisses from BlackRock Forest, located within the Hudson Highlands ofNewYork. The area wasmetamorphosed to granulit...
The standard method of assessing the available portion of the nutrient reservoir of a forest soil is to use a neutral salt solution, such as NH4OAc, to extract the exchangeable plus dissolved ions, wh...
The scanning electron microscope (SEM) is useful in the identification of biogenic opal. Opaline spheres, cups, and scrolled or convoluted sheets were identified in both soil and vegetative isolates. ...
