- Title:
- The Chemical Properties of Bitter Water and Its Rational Utilization in the Loess Plateau
- 摘要:
- 本文主要讨论黄土高原苦水地区地下水及地面水的化学特性和灌溉水质评价等问题。根据当地灌溉实践经验，通过水的矿化度和灌溉系数间的相关分析。说明在清水河、祖厉河、渭河等流域内，矿化度小于7g/l 的苦水，可作灌溉用水；而在泾河及洛河流域内，矿化度小于6g/l 的苦水才能作为灌溉用水。苦水水质低劣，只能在气候干旱、淡水极缺、排水良好的土壤上灌溉和种植耐盐作物。
- Abstract:
- The chemical properties of the ground waters and surface waters, and the evaluation for the quality of irrigation water in the ariel and semi-arid areas of the loess plateau were studied in this paper.The results obtained from analysis of relationship between salt concentration and irrigation coefficient of waters in this region showes that these waters with salt content of less than 6g/1 may be used for irrigation in the Jing and Luo river valley.And the waters with salt content of less than 7g/1 also may be used in Qingshui,Zuli and Wei river valley. Because the bitter(saline)water is very low in quality,therefore it only may be used for irrigating tolerant salt crops on conditions that the soils have excellent internal and surface drainage and the fresh water is very lack in the arid region.
