地温观测方法的研究

Study on Method of Ground Temperature Measurement

利用铂、铜、热敏３种电阻传感器的遥测地湿仪与台站现用玻璃地温表，在不同天气条件下，用不同安置方法进行大量的对比试验，探讨地面、草面、地中不同深度温度的最佳观测方法。得出：地面温度应用体积小棒状传感器的多点采样平均来代替单点一次采样；地中温度表用直埋式与套管式无大差异；草温为农业服务有重要意义等结论。为遥测地温的观测方法提供科学依据。

Using platina, copper, thermosensitive resistors as sensors together with telemetering instruments ground tepmerature is measured and compared with that measured with standard glass ground thermometers under different weather conditions and sensor disposition. The best temperature observation method for ground and grass surface and at different depth under ground is discussed.The conclusion is that ground temperature should be measured by stick-shaped sensors of small size and,single point sampling should be substituted by averaged multiple point sampling.There is no obvious difference between directly buried and tubed buried. Grass temperature is of great importance to the argriculture service.
