Abstract: | The vegetation pattern in the upstream of Minjiang River, and its relationship with environment factors, such as landscape
position (elevation, slope, aspect), precipitation and temperature and soil are analyzed in this paper. The data used in this
paper were based on the landscape map derived from 1994 TM imagery. The results were as follows: 1) dominant landscape types
were forest, shrub land and grassland, which were very similar in terms of area ratio (32.87%, 31.85% and 28.44%, respectively);
2) the patch shape of conifer forest and mixed forest was complicated while that of broad-leaved forest and cultivated land
was simple; 3) the fragmentation of conifer forest and mixed forest was serious in contrast with low fragmentation of broad-leaved
forest and cultivated land; and 4) closed scrub and grassland had a high contagion and good connectivity while mixed forest
had a lower contagion and bad connectivity. In addition, the vegetation distribution pattern of upstream of Minjiang River
was closely related with elevation and temperature, but the relationship between vegetation and precipitation was not statistically
significant.
