土壤温度检测及其与含水率关系研究
Detection of soil temperature and its relationship with moisture content
摘要
Abstract
In attempt to remotely monitor soil moisture and explore relationship of soil temperature and soil moisture content,the IRI1011 thermal infrared imager was used to measure soil temperature at different depth including 0 ～ 5 cm、0 ～ l0 cm、0 ～ 15 cm、0 ～ 20 cm in a small area range in this paper.Relationship between soil temperature and soil moisture content was further analyzed.Results showed that correlation coefficient R2 between average soil moisture content and temperature in depth from 0 to 20 cm was 0.658.Soil temperature was measured at different times of the day,and results showed that,at noon,correlation coefficient R2 between moisture content of surface soil and temperature was 0.794,under the condition that there was no obvious changes in external environment.关键词
