【摘要】 通过野外和室内实验对甘肃省安西县一试验区土壤水盐变化进行分析,得出在一定的灌水方案下的土壤盐分分布情况以及脱盐状况,并对适宜本地区特点的水盐调控措施进行了初步探讨,也为水盐动态模型的建立及排水多准则优化提供实验基础更多还原

【Abstract】 Wilh the analysis to the variation of water-salt in soil and by means of indoor and outdoor experiments made in Anxi country, Gansu Province, the distribution of salt and the condition of salt dilution in the case of irrigation are concluded. A primary discuss is made on the adjustment measures to local water-salt characteristics. The experimental foundations for the construction of water-salt dynamic simulation and the multi-principle optimize for drainage are supplied.更多还原
