陜西省土壤溫度和水分狀況估算
[Abstract]:Soil temperature and soil moisture are two important diagnostic characteristics of soil classification in China. The water and heat status of soil is directly affected by near-surface temperature and precipitation, and the soil moisture and temperature can be estimated by climatic factors. Based on the surface meteorological data of 85 meteorological stations in Shaanxi Province for 30 consecutive years, the soil temperature and moisture status and their spatial distribution in Shaanxi Province were studied by means of geostatistics and (JNSM) model. The results show that the soil temperature is: Qinling mountain area and its north is warm, Hanjiang River valley area and its south is thermal; The soil moisture conditions are as follows: drought in the north of the Great Wall, semi-dry and moist in the Loess Plateau and Guanzhong Basin in northern Shaanxi, and humid in the south of Qinling Mountains, usually only in the southern part of Zhenba County and Zhenping County in the southernmost part.
