为探讨黄土高原耕地的理化性质，为盐碱草地的改良提供依据，分别于2008年秋季、2009年春季和雨季在右玉县对耕地取0-10cm、10—20cm、20～30cm、30—50cm、50—75cm、75—100cm层次土壤样品，分析其物理特性和化学特性。结果表明：样地平均土壤容重为1．41g/cm3，平均比重为2．70，土壤呈砂质壤土的杌械组成。所调查土壤偏碱性，土壤pH为8．36，破化度为13．35％。土壤可溶性盐分含量0．38％，阴离子以Cl-和HCO3-为主，阳离子以Na＋和Ca2＋为主，有机质和全氮缺乏。

The physico-chemistry properties of cultivated land were studied for improved the saline-alkaline grassland. The cultivated land in 0-10 cm, 10-20 cm, 20-30 cm, 30-50 cm, 50-75 cm, and 75-100 cm depth respectively at the autumn, the spring and the rainy seasons were sampled to measure the physic-chemistry properties. The results indicated that the average volume weight of soil was 1.41 g/cm3, and average specific gravity of soil was 2.70. The texture composition assumed the sandy loam. The soil alkalized degree was high with average soil pH 8.36 and average exchangeable sodium percentage above 13.35%. The average soil soluble salinity content was 0.38%, the anion by Cl- and HCO3- primarily, the positive ion by Na＋ and Ca2＋ primarily, the organic matter and the total nitrogen lacked.
