Abstract:

We,taking Fuping watershed of the Daqing River as a research object,investigated the changes of landscape pattern and ecosystem services over a period of time from 1985 to 2015,and analyzed the relationship between them.The results show that the landscape pattern of the study area changed significantly during the investigation period,the urban landscape,forest landscape,agricultural landscape and water landscape area changed positively,and the unused land landscape and grassland landscape changed negatively.The mean patch area increased,the connectivity of each landscape type is better,and the landscape structure became more stable.The value of ecosystem services in the study area increased before 2000,and decreased after 2000,the forest land made the greatest contribution to the total ecosystem value of the study area,followed by cultivated land and grassland.In the value of single service,the contribution rate of soil conservation was the largest,followed by biodiversity maintenance,air regulation and climate regulation.There is a good correlation between ecosystem services and patch density,landscape shape index,mean patch area,area weighted mean shape index,area weighted mean fractal dimension and aggregation degree at the landscape level.

Key words: landscape pattern, ecosystem services value, Fuping watershed of the Daqing River, monitoring of dynamic changes, remote sensing
