中文摘要	水分是黄土区植被恢复与重建的重要限制因子,土壤水分是植物生长和发育的必要环境因素.由于土壤水分供给的有限性,使它成为植物生长和生存的限制性因素.因而,对土壤水分的研究具有十分重要的意义.在土壤水分研究现状的基础上分析植被恢复与重建,并从研究的方法与内容方面进行论述,提出当前土壤水分研究中存在的问题与解决对策.
英文摘要	Water is a crucial factor affecting the restoration and regeneration of ecological environment in the loess areas, and soil moisture content is an indispensable factor to the growth of plants. Precipitation in the Loess Plateau of China is relatively less comparing with east China and south China, and its temporal and spatial distribution is uneven. Loess is thick in the Loess Plateau, the redistribution of soil moisture is significant, that is the moisture conditions are good in the valleys but the soil on the loess bridges is arid, so it is difficult to re-generate the ecological environment in the loess areas. Currently, the studies on soil moisture content in wood-lands have been shifted from qualitative description to quantitative analysis, and the research targets include landscapes, ecosystems, plant communities and species, etc. Soil moisture content is generally a restrictive fac-tor to the growth of plants because of its limited supply in the loess areas. Therefore, it is of significance to study soil moisture content. In this paper, the previous studies on soil moisture content are summarized from the study methods and study contents based on analyzing the actuality of study on soil moisture content in restoration and regeneration of vegetation. Moreover, some problems in the relevant researches are also discusses, and their solutions are put forward.
