Based on the RS and GIS technology, the remote sensing imageries MSS in 1975, ETM in 2000 and CBERS-2 in 2007 have been used as main data source in this paper. Wetland current distribution, spatiotemporal change principle and transition matrix have been analyzed in order to realize the wetland change situation in Northeast China during the 30 years. The results show that the wetland area in Northeast China, on the whole, is decreased first and then increased. The dramatic change happened in mire and constructed wetland. Mire is decreased first and then increased, but the whole is still decreased. While, constructed wetland is increased continuously. Constructed wetland increased owing to the transition from mire and non-wetland. The level of the transition from mire to constructed wetland is lower. In Northeast China, human activities have a great impact on wetland change than nature factors.

Northeast China hosts one of the largest Cenozoic intraplate volcanic regions in the world. However, the mechanisms that generate the volcanism, its spatial-temporal distribution, and compositional signatures remain highly debated due to the lack of high-resolution images of the mantle’s thermochemical structure. We jointly inverted new surface-wave dispersion data, surface heat flow, geoid height, and elevation data to image the fine-scale thermal and compositional structures beneath northeast China and infer regions of partial melting in the mantle. Our model reveals a complex circulation pattern in the asthenosphere and a highly variable lithospheric structure. Combining predictions from our model with independent geochemical data from recent basaltic volcanism, we demonstrate that the generation, location, and composition of intraplate volcanism in this region are controlled by the interaction between shallow asthenospheric circulation and lithospheric thickness. The modeling approach and correlations between basaltic composition and mantle state identified in our study are globally applicable to assessing mantle conditions over time in other continental regions.
