宁夏沙坡头灌区土壤盐渍化影响因素分析
Discuss the Relation About Groundwater and Soil Salinization of Ningxia Shapotou Irrigated Area
摘要
Abstract
Based on the data of soil salinization investigation in Ningxia Province and taking Shapotou irrigation area as an object,the paper ana-lyzed the influence of salinization of higher elevation irrigation area to the lower elevation irrigation area and discussed the relationship between sa-linity,depth of groundwater and soil salinization. The conclusions are that a)the Nanshantaizi pumping irrigation area impacts the low irrigation ar-ea,the range is 350 ~ 550 m,from high to low irrigation area extending direction,the soil salinization from heavy to light. b)As the result of model,before the spring irrigation,the shallower the groundwater depth is,the faster the soil salt accumulation and higher the salt content will be. c)The groundwater salinity affects the degree of soil salinization. The higher the salinity is,the more serious soil salinization will be.关键词
