南水北调中线工程对钟祥市生态环境的影响

Impact of middle line of South-to-North water diversion project to the eco-environment of Zhongxiang City

分析了南水北调中线工程实施后,对湖北省钟祥市水生态环境、农业生态环境和气候环境的影响:导致境内汉江水质下降、污染加剧、水资源日趋紧张、水生生物多样性受到破坏;壤土型和粘土型的潮土和灰潮土的土壤质量和结构将明显恶化,对农业生产产生严重影响;蒸发量增大,相对湿度降低,不利于局地小气候的形成。

After the project being put into practice, the authors analyzed the impacts of middle line of South-to-North water diversion project to the water enviroment, agriculture environment and climate environment of Zhonxiang City in Hubei Province： the water quality of Hanjiang River will be descened, the water pollution will be worse, the water resources will be scare, and the variety of hydrophilous biology will be destroyed. The quality and structure of the Fluvo-aquic soils and grey Fluvo-aquic soil will be obviously deteriorated. These impacts will be prducted serious effect to the agriculture development. The evaporative capacity will be increasing and the relative humidity will be decending that will be unfavorable to form the local microclimate.
