摘      要：To study the causation and ecological effect of Corridor phenomena in the Longitudinal Range-Gorge Region (LRGR) in South China and South-East Asian. Supported by the geographic information system (GIS), vegetation, climate and topography database of the LRGR are founded. The northernmost limit of the tropical rain forest is 28 22, which has been promoted 3 or 4 latitude by Vapor Corridor Phenomenon. Through ANN analysis, landform proves to be a very important factor affecting NPP distribution. Affected by longitudinal valley landform and monsoon, moisture and quantity of heat has a longitudinal belt distribution, and NPP distribution has seemly distribution. Take Lyonia ovalifolia, Myrica nana scrub as an example, high NPP value-scrub distributes on a wet-tongue area in the valleys. The minimum temperature sensitive value to NPP is 1.588, and altitude is 1.053, precipitation is 1.006, aspect is 1.003. Corridor phenomenon in the LRGR formed special moisture and heat patterns and brings about a series of ecological effects, such as influencing space distribution of vegetation form and NPP spatial patterns of both vegetations and plants.
