A Comparative Study on Influence on Plant Communities and Mutual Species and Response to Different Temperature Gradient and Combination of Water and Heat in Inner Mongolia Steppe Region of Temperate Zone
1.The natural reserve of Laojie Rance of Xixia county is situated in the transitional region from the subtropical to the warm zone. The plants in southern and northern arcas are in-seted with and are very ich,Spermatophytes include about 131 families,864 genera,and 1354species.
The fourtwos highyield corn cultivation technology is intended to reform the ripe cycle in the northwestern part of Hubei province, which is a transitional area between the north subtropical zone and the warm zone.
To study the “four twos” high yield corn cultivated technology is intended to reform the ripe cycle in the northwestern part of Hubei province, which is a transitional area between the north subtropical zone and the warm zone. More specifically, the technology is intended to change the two ripe cycle (wheat→corn) into a three ripe cycle (winter wheat→spring corn→summer corn) in dry land.
By using MM5(V3-2), the transformation of TOM (a tropical storm in 1996 in Northwestern Pacific Ocean) from tropical storm to extratropical cyclone is simulated, also, the thermodynamic and dynamic structures are analyzed during Tom's evolution.
Pinus tabulaeformis forests form the most important vegetation cover in the warm temperate regions of China.
With a temperate continental monsoon climate, the mountain area belongs to the warm temperate deciduous broad-leaved forest region.
The bryoflora could be divided into 10 geographical elements: north temperate element make up the majority, accounting for 52.11% of the entire known bryoflora, and another belongs to the East Asian element, accounting for 19.25%.
All temperate elements, not including 14 endemic to China and 31 Cosmopolitans, were added up to 188 species, which took 88.3% of all the entire known bryoflora in Mt.
In temperate forest ecosystems, seasonal changes of soil resource availability will alter the pattern of carbon allocation to belowground.
The spatial structure of surface air temperature (SAT) anomalies in the extratropical latitudes of the Northern Hemisphere (NH) during the 20th century is studied from the data obtained over the period 1892-1999.
On the other hand, the warm SST anomaly over the western and central Pacific, as a forcing, may lead to a specific pattern of the northern extratropical atmosphere, which is favorable to the strong EAWM activity.
Excitation of Low-level cross-equatorial flow in the western Indian ocean results from an interaction between extratropical perturbations moving eastward across the South African-Malgassy region of the Southern Hemisphere.
This paper briefly reviews the state-of-the-art in this research area: the nature of the Madden-Julian Oscillation, its relation to monsoonal and extratropical circulations, and the current theoretical understandings.
A diagnostic study of explosive development of extratropical cyclone over East Asia and West Pacific Ocean
