Abstract In order to study the dynamic change law of landscape pattern in the basin with the cascade flow
characteristics of plateau-mountain-plain-coastal ecological elements, 7 Landsat remote sensing images of Yongding
River Basin from 1980 to 2020 were taken as the main data source, and the evolution characteristics of landscape
pattern in Yongding River Basin in recent 40 years were analyzed by comprehensively using the methods of
landscape area dynamic analysis, landscape pattern index and mathematical statistics, and its driving factors were
revealed. The results showed that: 1) From 1980 to 2020, Yongding River Basin was dominated by cultivated, forest
and grass land, accounting for about 90%. The area of cultivated land and grassland had decreased by 1 376.38 and
2
463.42 km respectively in the recent 40 years, the area of construction land and forest land had increased, and the
dynamic degree of comprehensive land use had changed the most from 2015 to 2020. 2) At the type level, the
fragmentation degree of construction land patches had decreased significantly, while the changes of other land types
were not obvious. At the landscape level, Shannon Diversity Index (SHDI) and Shannon Evenness Index (SHEI) had
increased from 1.29 to 1.35 and 0.67 to 0.75, respectively; the overall landscape structure tended to be complex, the
heterogeneity had increased, the degree of agglomeration had decreased, and the landscape fragmentation had been
intensified. 3) The change of watershed landscape pattern was affected by socio-economic factors, natural factors
and policy factors, in which socio-economic development was the main driving force, and economic development
