伽师县盐碱荒地土壤盐渍化趋势预测分析

Prediction and Analysis of Soil Salinization Trend of Saline-Alkali Wasteland in Jiashi County

为实现伽师县盐碱荒地的再利用,在取样及室内试验的基础上,通过建立数学模型开展区域盐碱荒地土壤盐渍化趋势预测。结果表明,伽师县荒地含盐量普遍高于耕地及草地;在相同条件下黏性土较砂壤土更易积盐;不采取治理措施的情况下,随着时间的推移,区域盐渍化将进一步加深;地下水位及农业灌溉是造成伽师县盐碱荒地盐渍化的根本原因。因此,应结合实际情况在实施地下水位调控的前提下,加强区域排盐设施的修建及完善。结论可为缓解伽师县土地资源利用紧张及制定盐渍化治理方案提供参考。

To facilitate the reuse of saline-alkali wasteland in Jiashi County,mathematical models are established based on sampling and laboratory experiments to predict the trend of soil salinization in the region.The results indicate that the salt content in the wasteland of Jiashi County is generally higher than that in cultivated and grassland areas.Under similar conditions,clayey soils tend to accumulate more salts compared to sandy soils.Without proper management measures,regional soil salinization is expected to worsen over time.The groundwater level and agricultural irrigation are identified as fundamental causes of salinization in Jiashi County’s saline-alkali wasteland.Therefore,it is necessary to strengthen the construction and improvement of regional desalination facilities in conjunction with the actual situation while implementing groundwater level regulation.These findings can serve as reference for alleviating the pressure on land resource utilization in Jiashi County and formulating salinization control plans.
