草原地区城市生活污水土地处理工程生态效应研究

EcologicaI study of land treatment system for municipal sewage in Steppe region

  • 摘要: 阐述了城市污水土地处理工程在草原地区生态功能及其环境影响的作用、污水灌溉下几种人工林群落的演进和生态安全问题,指出坡向和地形对草原地区造林非常重要,河谷地段或灌溉人工林地10~15年内已发育成稳定郁闭的纯林生态系统,并形成用材林和苗木基地,而干旱阳坡或半阳坡不宜发展林地。

     

    Abstract: The ecological functions and environmental influence of wastewater land treatment engineering in Steppe region are reviewed in this paper. The succession and ecological safety of artificial forest communities in the condition of wastewater irrigation are analyzed also.The aspect and tolxgraphty are the key factors to foresmtbn in steppe region.The artificial fOrestS in valley or with enough irrigation grow quickly within 10~15 years,that are used as the base of wood and seedlings.Droughty sunny slope and half sunny slope are not suitable to forestation.
