Abstract:: The changes of landscape in the latest fifty years were analyzed based on the method of GIS spatial analysis and ecological quantity analysis through Arcinfo and Fragstats.The results indicated that:the analysis on the index of patch showed that the spot number of cultivated land firstly increased from 499 in 1953 to 820 in 1986 and then decreased to 780 in 2000.The LSI of cultivated land increased from 52.72 in 1953 to 66.64 in 1986 and decreased to 64.18 in 2000,and the fragmental degree of cultivated land firstly became larger and then became smaller;the number of forestland and grass spot land firstly increased and then decreased,their fragmental degrees firstly became bigger and then smaller;the number of spots of construction land increased from 24 in 1953 to 46 in 2000,and fragmental degree of construction land also increased from 6.92 in 1953 to 12.18 in 2000.The analysis on index of landscape showed that the PD increased from 0.56 in 1953 to 0.61 in 2000 and then decreased to 0.59 in 2000.Its shape index increased from 45.75 in 1953 to 50.35 in 2000.It showed that human influence on this area increased.
