Correlation between Soil Water Content and Thermal Conductivity in Different Land Use Types
摘要
Abstract
Objective] To explore the correlation between soil water content and thermal conductivity in different land use types. [Method] Four land use types in the open air were used as the test plots. Soil water content was measured at 0-15 cm layer by oven-drying method. Unsteady heat probe pulse technology was used to measure the soil thermal conductivity. [Result] Under the four land-use types, change range of soil water content was 12. 79% -25. 08%;change range of soil thermal conductivity was 0. 481-1. 291 W/(m·K). The sampling data between adjacent sampling point in farm land and bare land showed higher fluctuation, while the sampling data in the shrub land and grass land had higher continu-ity. [Conclusion] The soil water content and thermal conductivity in the four types of land utilization show a positive correlation relationship in the natural state.关键词
