我国土壤墒情预报模型的研究进程及发展方向

适时精准的土壤墒情预报技术,对于农业节水具有重要的社会和经济意义,为此,在了解20世纪70年代以来国内外土壤墒情预报模型研究进展的基础上,归纳分析了国内外土壤墒情预报模型的研究进程及其特点,比较分析了国内土壤墒情预报模型研究与国外的差距,由此初步认为,今后国内土壤墒情预报模型研究的主要方向为:侧重土壤墒情预报模型的非均匀性、随机性和区域性的研究,注重其信息网络化、综合化和实用化的全面深入研究.

Research Progress and Development Direction of the Forecast Models of Soil Moisture Content in China

The timely and precise technology of soil moisture content forecast has the important societal and the economical significance in saving agricultural water.Therefore,on the basis of understanding the main research progress of soil moisture content forecast at home and abroad since 1970 s.This paper summarizes the main research advances and characters,and analyzes the existing disparity in the current studies on the forecast models of soil moisture content in China.It may be inferred that the domestic forecast models of soil moisture content have these main directions such as focusing on non-uniformity,randomness and regional studies;and attaching greater importance to its information network,and comprehensive practical study in a deepgoing way.
