摘要
水是维系半干旱地区农业生态环境的主导活跃的因子.由于半干旱地区相对丰富的水资源,导致了土地盐碱化等一系列环境问题,不仅妨碍了农业生产的发展,也破坏了半干旱地区土地生态系统。对水资源的合理开发与利用,将有利于半干旱区农业生态环境的改善,促进农业生产的发展.本文综合分析了半干旱的吉林西部地区水文地质环境与土地盐碱化的关系。
Water is an adominant and active factor for maintaining geologic environment of agriculture in semiarid region. Because of relativitily abundant water resource, it leads to a sequence of environmental problems such as land salinization. It not only hinders the development of agriculture, but also destroys land ecological system of semiarid region. Developing and using reasonably water resource, will benefit to improve ecological environment of agriculture in semiarid region, and lead to a great development of agriculture. This paper is based on comprehensive analysis of hydrogeologic environment to discuss the relations between water resource and land salinization in semiarid region.
