吉林西部土地盐碱化的生态地质环境研究

本文从生态地质环境的角度对吉林西部土地盐碱化的成因进行了系统分析 ,认为吉林西部土地盐碱化的形成过程 ,是在脆弱的生态地质环境基础上叠加了人类不合理活动的综合结果。脆弱的生态地质环境为土地盐碱化的发生提供了客观基础 ,在众多的生态地质环境因素中 ,又以气候、地形、地质、水文和水文地质及人类活动的影响最为显著。地质环境为土地盐碱化提供了物质来源并塑造了发育空间 ;气候条件决定了盐碱化发生的必然性 ,特别是冻融作用不可被忽视 ;水文及水文地质条件对土地盐碱化产生更直接的影响 ;人类不合理的经济活动触发和加剧了土地盐碱化的发生。

Study on the Eco-geo-environment of Land Salinization in West Jilin Province

This article systematacially analyzed the cause of land salinization in the West Jilin province on the eco geo environment. The authors deemed that the forming process of land salinization was a comprehensive result of irrational human activity overlapping on the vulnerable base of eco geo environment. The vulnerable eco geo environment provided substance and location for land salinization; the special climate decided inevitability; irrational human activity triggered and aggravated the land salinization.
