北方典型农业生态区陆面过程研究简述

介绍了关于北方地区的陆面过程观测、模式发展以及陆气相互作用研究方面所取得的主要研究成果。分别从陆面过程观测、陆面过程数值模拟和陆面过程模式中土壤湿度数据同化3个方面,概述了国内开展陆面过程研究的主要内容。指出了陆面过程观测、陆面模式研究中存在的不足以及陆面过程数据同化发展的新途径。分别介绍了在西北干旱区和锦州农田开展的陆面过程观测和数值模拟研究。最后总结了陆面过程研究中存在的问题和未来发展的方向。

A Brief Introduction of Study on Land Surface Processes in Typical Agro Ecological Regions of North China

This paper introduces the research results of the study on the observation of land surface processes, the develop-ment of models and the study of land atmosphere interaction in North China. The main contents of the study on land surface processes in China are summarized from three aspects: land surface observation, land surface process numerical simulation and soil moisture data assimilation in land surface process model. The shortcomings of land surface processes observation and land surface models is proposed, and new approach to the development of land surface data assimilation is proposed. Intro-duces the observation and numerical simulation of land surface processes in arid areas of Northwest China and in Jinzhou famland. Finally, the existing problems and future development of land surface process research are summarized.
