【摘要】 土壤水分是影响植物生长的重要因素,尤其是在降水少,蒸发量大的黄土地区,简要论述了黄土区土壤水分研究的历史与现状,分析了林木单株耗水量和应用水量平衡方法的研究,并重点概括了目前较新的几种林木蒸腾研究方法。更多还原

【Abstract】 The soil water is the main factor of the plant’s growth,particularly in the loess area where the landfall is few and the evaporation is more.The history and the present condition of the soil water research in the Loess Plateau are described.At the same time,the water consumption properties of single-tree and the principle of hydrological balance are analyzed.In the end, some new methods of transpiration are generalized.更多还原
