中文摘要	综合环境因素影响下土壤中钠的迁移和累积是阐明土壤次生盐渍化演替规律的重要内容之一。本研究以甘肃省秦安县兴国镇郑川村的3个有代表性的盐渍化果园为研究对象,通过对苹果(Malus pumila Mill.)树生长危害期(48月)的环境因子(果园近地面空气温度、相对湿度、潜在蒸发量、降雨量、土温、土壤水分)进行定点定位监测以及果园土壤表层不同土层水溶性Na+的定期采样分析,利用相关和回归分析的方法,研究了半干旱地区果园表层土壤水溶性Na+与环境因子的关系。结果表明,气温升高有利于表层不同土层水溶性Na+的累积,空气相对湿度增大能抑制表层不同土层土壤水溶性Na+的累积。不同土层水溶性Na+的含量与土温呈正相关关系,与0～2cm、2～5cm、10～15cm、15～20cm、20～25cm土层土壤水分含量呈负相关关系,与5～10cm土层土壤水分含量呈正相关关系。水分亏值分别与0～2cm、2～5cm、10～15cm、15～20cm、20～25cm土层水溶性Na+的含量呈正相关关系,与5～10cm土层水溶性Na+的含量呈负相关关系,并科学的提出表层土壤5～10cm土层是水溶性Na+对环境因子(蒸发量与降雨量)反应的灵敏层。
英文摘要	Transportation and accumulation of sodium ion is one of important matter that elucidated the succession law of soil secondary salinization under integrative environment factors. The object of study is three typical salinization orchards in Zhengchuan Village of Qinan County in Gansu Province. Environment factors (evaporation, rainfall, near-ground air temperature and relative humidity of orchards, soil temperature and soil moisture) were supervised by fix orientation in fields during apple (Malus pumila Mill.) trees growth. And transportation and accumulation of sodium ion through measuring contents of water-solubility sodium in topsoil in different soil layer. Relationship between environment factors and water-solubility Na+ accumulation in orchard topsoil in semi-arid regions were studied by using correlation and regress method. Results indicate that the content of water-solubility sodium increased under air temperature enhance, and the content of water-solubility sodium decreased under air relative humidity enhance. Water-solubility sodium showed positive correlation with soil temperature in different soil layer, with soil moisture were negative correlation in soil layers of 0～2 cm, 2～5 cm, 10～15 cm, 15～20 cm and 20～25 cm, respectively, with soil moisture was positive correlation in soil layer of 510 cm. Water deficit value were positive correlation with soil moisture in soil layers of 0～2 cm, 2～5 cm, 10～15 cm, 15～20 cm and 20～25 cm, respectively, with soil moisture was negative correlation in soil layer of 5～10 cm. And the conceptsensitive layer in soil layer of 5～10 cm is thus brought forward that expressed soil water-solubility Na+ in response to environment factors (evaporation and rainfall ).
