Landscape Spatial-Temporal Pattern Analysis on Change in the Fraction of Green Vegetation Based on Remotely Sensed Data:A Case Study in Haidian District, Beijing
Abstract:Modern land surface parameterizations(LSP)in numerical weather prediction and general circulation models require specification of two major vegetation characteristics——vegetation type and vegetation amount. Vegetation amount is parameterized through the fraction of green vegetation and the leaf area index, the number of leaf layer of the vegetated part. The fraction of green vegetation, the radio of vegetation occupying a unit area, is a very important parameter in development of climatic and ecological mod...
