英文摘要Currently, impacts of rapid cropland reclamation and its intense structural changes in internal paddy-upland on ecosystem service are insufficient in Sanjiang Plain, China. Further, land management systems of Sanjiang Plain consist of state-owned and private farms; however, exploring the impact of different land management systems on "land use-landscape-ecosystem service" is still lacking. To reveal this issue, the integrated methodology of "land dynamic tracking-landscape index-improved ecosystem service assessment" was established. Results are displayed below: From 1990 to 2020, land use was featured by decreases in forest (-3308.62 km2), grassland (-6030.86 km2), waters (-475.81 km2), and unused land (-3037.27 km2), with a slight increase in constructed land (+403.25 km2) and a rapid increase in cropland (+12,447.56 km2). Although nearly equal increments of cropland on state-owned and private farms (i.e., 6156.70 km2 vs. 6290.86 km2) were monitored, different cropland structure changes were still revealed, namely a drastic expansion of paddy fields (13,788.32 km2) and an acute decrease in upland crops (-7631.62 km2) on state-owned farms, but both a slight increments in paddy fields (5920.08 km2) and upland crops (370.78 km2) on private farms. For landscape, private farms were more fragmented (SHDI = +0.63%), causing a decrease in aggregation (AI = -0.56%) and a more complex shape (LSI = +23.3%), by contrast, state-owned farms displayed an increased integrity (SHDI = -9.88%), along with an increase in aggregation (AI = +0.43%) and simplified shape (LSI = -13.30%). Evaluated ecosystem service value changed from 338.62 to 296.25 billion yuan from 1990 to 2020, a loss rate of 12.58% in Sanjiang Plain. Then, a new finding showed a higher loss rate on state-owned than private farms (i.e., 30.15% vs. only 6.18%). This study revealed differentiated processes of "land use-landscape-ecosystem service" in different land management system regions in China, providing new findings in the fields of land management system, ecological landscape, and environment.
