| 摘 要： | 近年 ,随着国民经济的迅速发展 ,水资源日益不能满足它的需要 ,常常引起农业用水大户与其他用户争水的矛盾。这在水资源匮乏的地区尤为突出。人们在寻找解决方案时 ,又重新涉及对水资源的认识问题 ,其焦点在于是否应把土壤水作为一种水资源看待。本文从土壤水的特性及其对植物的有效性出发进行探讨 ,提出了土壤水资源的评价系数 (C) ,希望有助于讨论的深入开展。

| Abstract: | In recent years, water resource can no longer meet the rapid development of economy and this often causes conflict between big agricultural water user and other water user, especially in regions of water shortage. People have to face water problem again and look for other water as a resources.The author discussed the characteristic of soil water and its availability to plant. An equation for estimating the amount of soil water resource was presented. Based on the evaporation of atmosphere, the evaluation coefficient for soil water resource was suggested. |
