Impact of Land Transition on Landscape and Ecosystem Service Value in Northeast Region of China from 2000–2020

Drastic land pattern change has taken place in the northeast region of China, which may have a significant impact on landscape and ecosystem service. Up to now, insufficient renewal use patterns limit latest assessment transition service value. Meanwhile, adaptive value improvement method should be established. To solve this issue, integrated methodology land-use monitoring—landscape analysis—the promoted measurement is Results show that: (1) New evidence observed that cultivated Northeast China been reduced, with 309,610.33 km2 2010 309,417.52 2020, showing net area ?192.82 km2. This opposite increase compared past. (2) Shannon’s diversity index displays an upward trend, richer types higher fragmentation whole region. In addition, contagion total decrease 1.93, indicating patches distribute intermittently agglomeration degree these weakened.
