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.

Study on pattern and change on land cover stands an important aspect to global change. The spatial characteristics of ecological system show some familiar or disfamiliar principle with up-scaling or down-scaling process, which can be defined as spatial autocorrelation. In this paper, four typical parameters of ecological features, say Gross Primary Product (GPP), Net Primary Product (NPP), Normalized Difference Vegetation Index (NDVI), and Enhanced Vegetation Index (EVI), are selected to investigate the spatial variability on vegetative features in Longitudinal Range-Gorge Region (LRGR), Southwest China. Moran coefficient (MC) is calculated for spatial autocorrelation degree, and semivariance function is used for spatial variability and spatial heterogeneity analysis. The results show that: (1) the ecological features show negative autocorrelation in the whole region. The higher anisotropy is on north-south direction, and then on southeast-northwest direction. (2) The spatial variability scale is great on vegetative features in the whole region. (3) The autocorrelation distance on north-south direction is the greatest, then on southwest-northeast direction. Through the above analysis it can be found that the vegetative features are consistent with direction of landform in LRGR, which is shown on higher autocorrelation on south-north direction, and lower on west-east direction.

For discussing the evolution characteristics and correlation of the tributaries of the Nujiang, Lancang and Jinsha rivers in the northern longitudinal rang-gorge region of northwestern Yunnan, the relationships between some geomorphic parameters of the total, first- and second-order tributaries whose catchment areas are larger than 100 km(2) in the three rivers of the study area are analyzed and a series of correlation formulae are proposed. Results indicate that the corresponding order tributary systems of the three rivers have very high comparability especially for the first-order tributaries. The statistical relationships between catchment area and channel length of the corresponding order tributary systems indicate that the Nujiang and Lancang rivers have more commonalities than the Jinsha River, being very evident in the relationships between the total- and first-order tributaries. The relationships between catchment area and channel gradient also indicate that there is more high comparability between the Nujiang and Lancang rivers, being very evident in the relationships of the total-order tributaries. The causes leading to the high comparability between the three rivers are as follows. The geological tectonic comparability in the longitudinal rang-gorge region causes the comparability of landform and the comparability of land surface condition, thus causing the comparability of the geomorphic evolution in the study area. The Nujiang and Lancang rivers in the study area are located at the margin of Eurasia Plate. They are strongly controlled by the collision zone of the India and Eurasia plates. The Jinsha River in the study area is relatively far from the collision zone. It is controlled by the collision zone in relative low degree and its geomorphic evolution is relatively free. Furthermore, relative infirm runoff because of the relative arid climate in the Jinsha River reach led to the relatively low ability in alteration of the landform systems of the rive

This article, taking MODIS-EVI as an index, analyzes the spatio-temporal distribution pattern of vegetation in the southern Longitudinal Range-Gorge Region (LRGR) and explains its cause by ARCGIS and SPSS. The result shows that the regional difference of Enhanced Vegetation Index (EVI) is remarkable with apparent topographical effect, especially for longitudinal ranges. As to temporal heterogeneity, because of the existence of certain time difference of the monsoon air affecting the study area, in addition to the obvious regional difference in spatial distribution of EVI, this kind of regional difference is significantly correlated in location with macro-landforms, especially the case of Ailao Mountain and Wuliang Mountain. As to spatial heterogeneity, by taking Ailao Moutain as a rough divide, because of the alternation of high mountains and gorges in the northwest of the study area, precipitation variance almost follows a sine curve from west to east with the mountain and gorge terrain, and hence EVI changes rapidly; while EVI changes insignificantly in the east of the study area because its terrain becomes rather gentle. The effect of longitudinal mountains on the reallocating of heat and moisture factors is the main cause for EVI regional difference. Especially, the effect of Ailao and Wuliang mountains on rainfall interception in rainy seasons and cold wave block in dry seasons is even more obvious. By counting statistical data of points at altitudes between 1400 and 1500 m in a cross-section, the annual mean precipitations in five sub-areas are 1244.67, 1081.44, 1111.41, 1033, and 807.11 mm respectively in rainy seasons, while the annual mean minimum temperatures are 7.93, 7.46, 7.28, 8.44, and 9.16 degrees C respectively in dry seasons.
