摘要:

Spatial pattern of landscape is a central issue in landscape ecology study. The main reason of landscape patten change owes to the external disturbance. In this article, retrospective sequential airphotoanalysis and statistical analysis of information on landscape development were used and two remarkable changes of landscape pattern in west Shenyang were identified:(a)one landscape element becomes a new matrix in place of the former one;(b)landscape proportions among several constiting elements changed significantly. This paper studied spatial pattern of the landscape using following quanta indices:(1)number and size of patches,(2)transition matrix of patches,(3)priority index of each kind of patch and(4)diversity and evenness indices of landscape.The results show that the landscape of west Shenyang has been more and more disturbed by human activities, so it becomes fragmentary throughout 30 years, and many blocky and island-like patches emerged.
