Abstract
With the water and soil conservation forests ofRobinia pseudoacaciain the Malian beach of Hongqi farm, Ji County, Shanxi province, as the research object, this study estimated the potential evapotranspiration in the open space outside the forest and at the heights of 3 m, 6 m, and 10 m in the forests with the climate data during 2011-2012 and the upgraded Penman-Monteith formula; then, this study explored the microclimate characteristics inside and outside theRobinia pseudoacaciaforest and thereafter revealed the vertical variation rules of potential evapotranspiration ofRobinia pseudoacacia. The results indicate that the air temperature, relative humidity, wind speed, and potential evapotranspiration at different heights above the ground surface showed similar changing trends, but with some variation during different periods. In addition, the weather also had impacts on the potential evapotranspiration. In April, July, and October, the change of potential evapotranspiration of theRobinia pseudoacaciaforests showed a bimodal curve in the sunny days and rainy days, while it showed a single-peak curve with quite small fluctuation in the rainy days. However, it showed a single-peak pattern even in the sunny days in January, and it showed no fluctuation in the snowy days in January.
Highlights
Global warming and the shortage of fresh water resources have become the most serious ecological and environmental problems faced by the sustainable development of human society in the 21st century
The results indicated that the air temperature inside the Robinia pseudoacacia forest had the similar variation at different heights; the changing extents at different times were various
The results showed that the average air temperature inside the Robinia pseudoacacia forest was lower than that outside the forest in July, the same for the maximum temperature and the minimum temperature
Summary
Global warming and the shortage of fresh water resources have become the most serious ecological and environmental problems faced by the sustainable development of human society in the 21st century. Robinia pseudoacacia is one of the main tree species in the soil and water conservation planning of Loess Plateau, analysis of potential evapotranspiration changing trends of Robinia pseudoacacia will be beneficial to explore the relationship. Advances in Meteorology between the plant’s water consumption and climate change and will provide the scientific basis for water circulation of soil-vegetation-atmosphere system. Robinia pseudoacacia is one of the principal species for soil and water conservation in western Loess Plateau, reasonable Robinia pseudoacacia artificial forest for soil and water conservation is extremely significant for the rational utilization of water resource. Rare research is conducted on the vertical potential evapotranspiration variation of Robinia pseudoacacia forest with season and time changes. All the conclusions are expected to provide the references for the rational water resource utilization during the process of Robinia pseudoacacia afforestation in the loess area of western Shanxi province
