- Abstract:
- Utilizing the remote sensing technology and GIS spatial analysis technology, we analyzed the spatiotemporal changes in climate and land uses in Liao River Basin of Jilin Province. Synthesizing the data on land use and land cover change (LUCC) through 1989—2012 and climatic data of 1962—2012, we revealed the response of land use change to climate change with the Spearman rank correlation analysis. The results indicated that the cultivated land and the woodland were the dominant land use types in the study area. The reductions of wetland, water area and the grassland degradation were occurring in this area. In recent five decades, mean annual temperature (MAT) increased significantly while mean annual precipitation (MAP) changed slightly. Through 1989—2012, MAT tended to decrease but MAP tended to rise. MAT decreased from the southwest to the northeast and MAP increased from southeast to northwest, which illustrated that the drier and warmer trend had improved in this area. The determinants of the response of land use types to climate change differentiated in different land use types. The spatial distribution of paddy field, water area and grassland presented a hysteresis response to MAP and showed a little response to MAT variation.
