| description | This paper examines the context of climate change and land use in the second Songhua River basin with the goal of improving runoff. The report begins by introducing the history of watershed runoff and the study area. The differences between various land use types and land use efficiency are examined using the watershed hydrology model from previous literature. The novelty of the paper is to compare the evapotranspiration of the model in different periods with the depth data of surface runoff. The results show that the simulation analysis and collaborative response strategy proposed here can adapt to the meteorological changes in the basin. The evapotranspiration of a watershed that was converted from woodland to grassland in 1970 was 34 mm, while that of a watershed that was converted from grassland to woodland was 32 mm, according to the results of the model test. The evapotranspiration of a watershed that gone from woodland to grassland in 2010 is 45 mm, compared to 39 mm for a watershed that has gone from grassland to woodland. The second Songhua River basin's surface water yield data can therefore be used to model and study the basin's runoff in real time.
HIGHLIGHTS
The overall change of runoff in the second Songhua River basin from 1970 to 2020 shows a certain growth trend.;
The evapotranspiration of the second Songhua River basin fluctuated greatly from 1970 to 2020.;
A runoff simulation and collaborative response model was constructed.; |
