南疆灌区无排水系统滴灌条件下地下水特性时空变化
Temporal and Spatial Variation of Groundwater under Drip Irrigation without Drainage System on the Oasis Irrigation Region in south Xinjiang
摘要
Abstract
Aimed at the secondary salinization under the condition of drip irrigation on fruiter in Oasis Irrigation Region of South Xinjiang,the groundwater depth,level and mineralization were observed in succession every month in 2010 by monitoring wells.The observed data showed that the groundwater depth,level and mineralization were higher in the growth period irrigation than before or after the irrigation.The most variation of groundwater depth and level was closed to 1 m,the groundwater mineralization was changed from 2 g/L to 5.8 g/L,its highest value appeared after spring irrigation.The results showed that drip irrigation can arise the groundwater level.So drip irrigation without drainage system will be a latent threaten to fruiter growth when the groundwater level is higher.At the same time,the role of drip irrigation washing salt is obvious.The soil salt can be moved and accumulated with the flowage of groundwater to downstream.关键词
