Soil Hydrothermal balance in farmland system and its response to human activities

Abstract

Abstract The problem of soil hydrothermal balance in farmland system is an important issue to study the formation and change mechanism of farmland climate and microclimate. As an important part of terrestrial ecosystem, the farmland ecosystem has dynamic changes in soil moisture and heat. Due to its particularity, the farmland ecosystem is also a land type directly affected by human activities. This paper systematically summarized the importance of soil hydrothermal interactions in farmland systems, the law of water and heat balance in farmland system and the recent research on the coupling model of hydrothermal balance in farmland system at home and abroad. In addition, this paper also elaborated the research progress of the response of farmland water and heat balance to farmland irrigation, film mulching and other human activities, so as to provide a theoretical basis for the effective use of farmland water resources and the cultivation of high-quality crops in the future.
