农田土壤盐渍化治理技术研究
摘 要
农田土壤盐渍化是全球范围内影响农业生产的重要问题，特别是在干旱和半干旱地区。自然因素如气候、地形和地下水位等，以及人为活动如不合理灌溉、过量施肥等，均对土壤盐渍化产生深远影响。本研究针对农田土壤盐渍化问题，系统分析了自然因素和人为活动对土壤盐渍化的影响，并比较了不同区域的盐渍化特征。在此基础上，提出了物理改良、化学改良剂和生物修复等治理技术体系，并探讨了这些技术的应用效果和实践经验。进一步地，本研究基于区域特征提出了治理技术组合方案，并建立了治理过程中的监测与评估方法。最后，构建了可持续治理模式，旨在为农田土壤盐渍化治理提供科学依据和技术支持。

RESEARCH ON THE SALINIZATION TREATMENT TECHNOLOGY OF FARMLAND SOIL
ABSTRACT
Salinization of farmland soil is an important problem affecting agricultural production worldwide, especially in arid and semi-arid areas. Natural factors such as climate, terrain and groundwater level, as well as human activities such as unreasonable irrigation and excessive fertilization, all have a profound impact on soil salinization. In this study, we systematically analyzed the effects of natural factors and human activities on soil salinization, and compared the salinization characteristics of different regions. On this basis, the governance technology system of physical improvement, chemical modification agent and bioremediation is proposed, and the application effect and practical experience of these technologies are discussed. Further, this study proposed a combination of governance technologies based on regional characteristics, and established the monitoring and evaluation methods in the governance process. Finally, a sustainable treatment model is constructed to provide scientific basis and technical support for the salinization treatment of farmland soil.
