| 6. | There is a very close support relation between the quantity or quality of soil - water resource and the development of human society 土水资源的数量与质量与人类社会的生存和发展密切相关,受到世界各国普遍关注。 |
| 7. | The theory and method for the classification , evaluation , forecast and planning of soil - water resource were discussed by using the information theory , the system theory , the cybernetics , and the space , information etc adavanced techniques as well as the computer skill 本文运用现代系统科学?信息论、系统论、控制论和现代高新技术?空间技术、信息技术和计算机技术,研究了土水资源分类、评价和预测、规划的理论与方法,取得了一些有意义的理论和应用成果。 |
| 8. | The rule about water flow in the unsaturated soil and the soil - water characteristic curve are described in this thesis in the first time step during the numerical simulation , the permeability coefficient is calculated according to the initial water content of the unsaturated soil , because of as shown in the soil - water characteristic curve has the hysteresis phenomenon 阐述了非饱和土中水流动的基本规律和土水特征曲线。由于土水特征曲线具有滞后的特点,提出了根据初始含水量来确定数值模拟初始时步非饱和土的渗透系数。 |
