| 英文摘要 | 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. |
