总结和回顾了干旱半干旱地区土壤湿度研究在区域气候变化研究过程中的重要性，详尽描述了干旱半干旱区土壤湿度数值模拟的研究现状。在过去几十年里，大型地面观测试验计划的开展、卫星遥感监测能力的加强促进了干旱半干旱地区陆面模式模拟土壤湿度能力的提高，推动了干旱半干旱地区土壤湿度数值模拟的研究进程。尤其是干旱半干旱地区气候观测站的建立，积累了长期宝贵的连续性观测数据，增强了检验卫星反演方法的能力，促进了陆面模式的参数化改进。近年来随着气象学、生态学以及水文学、土壤学等学科之间交叉合作的加强，气候变化背景下土壤湿度对碳、氮循环的影响研究得到越来越多的重视，尤其在干旱半干旱地区，局地碳通量和水分供应存在密切联系。因此，未来半干旱地区土壤湿度的研究不仅要开展观测计划，积累长期连续的高质量数据，改进卫星反演能力和模式参数化方案，而且要进一步深化和加强学科交叉内容的研究，分析气候变化背景下土壤湿度在生态学、水文学、土壤学等学科的变化形式和特点，多角度、多方向地开展和改进干旱半干旱地区土壤湿度的数值模拟研究。

The importance and current situation of researches about soil moisture in arid and semi-arid regions have been summarized and reviewed in this paper,especially about the numerical simulation of soil moisture.The large-scale observation experiments,re-mote sensing and land surface models are the main traditional methods of studying the variability of soil moisture and they promoted the development of study about soil moisture in the past periods.The foundation of climatic observation sites in drylands carried out the ac-cumulation of the long period of high quality data,which enhanced the testing ability of the retrieval methods of remote sensing and im-proved the parameterized scheme of land surface models.In recent study,the fields of research has extended from climate system to e-cosystem.The carbon and nitrogen cycle and the interaction between them and soil moisture have become a new research perspective, especially in drylands because there was a close relationship between carbon fluxes and soil moisture in drylands,so the carbon and ni-trogen cycle became a new research topic in drylands.The combination of traditional and modern methods that takes advantage of long term of observation,remote sensing,land surface model,carbon and nitrogen cycle is becoming the main aspect of conducting the soil moisture research.
