Based on the theory of landscape patterns and ecosystem service values, use the results of the interpretation of TM remote sensing images and socio-economic data in 2005, 2010 and 2015, and combined with GIS and Fragstats software to analyze and compare the changes of Agricultural landscape pattern and corresponding changes of ecological service value during 2005-2015.The analysis and comparison were carried out and the results showed that: 1) From 2005 to 2015, the spatial distribution of agricultural landscape in karst and non-karst areas of Quanzhou county changed to a certain extent, with obvious changes in the central and southern regions of karst areas and relatively scattered changes in non-karst areas. In agricultural landscape, the increase of water area in non-karst area is more than twice that of karst area, but the dominant landscape types of karst and non-karst areas have not changed. In both regions, the agricultural landscape has undergone significant changes, but the rate of change in karst area is greater, indicating that the change in karst area is stronger and more significant than that in non-karst areas. 2) In the past 10 years, the area of agricultural landscape in Karst was reduced by 472.23 hm2, and the non Karst area decreased by 476.28 hm2, but the reduction rate of Karst area was higher than that of non Karst region. Compared with the non Karst area, the landscape in Karst area is more fragmented, the patch shape is more dispersed and complex, and the landscape heterogeneity is even higher. On the one hand, the change of landscape pattern in karst and non-karst areas is due to the requirements of urban construction, industry and traffic layout. On the other hand is affected by the policy, making agricultural landscape internal change. 3) In the past 10 years, the total value of ecosystem services in prefectures and counties increased continuously, but the increase was small. In addition, the value of ecosystem services was reduced by RMB 1 million in karst areas. On the contrary, District ecosystem service value it increased by RMB 4 million in the non-karst areas. It can be seen that human activities have affected both karst and non-karst areas, but the influence of karst area is larger, leads to a decrease in karst area ecosystem service value. Among them, the largest contribution rate to the decrease of service value of the two regional ecosystems is the decrease of forested land, which reaches 78% in karst area and 83% in non-karst area. During the study period, although the value of ecosystem services provided by woodland decreased, the value of ecosystem services provided by water landscape increased. The increased value of ecosystem services in the two regions is due to the increase in water landscape. Since the forestry has a decisive role in the value of the ecosystem services of the two regions, it would be helpful to improve the ecosystem services of the study area, and improve the overall value of ecosystem services in the study area. %U https://www.rddl.com.cn/EN/10.13284/j.cnki.rddl.003060
