南水北调受水区地下水压采与城市供水安全问题探讨

However,it is inevitable to decrease the groundwater level around the mining area and even to influence the water supply safety of the constructed groundwater source fields.

为保证矿区安全开采,采矿本身要求排出大量的矿井水,这不可避免地使附近的地下水水位下降,并可能影响到已有地下水水源地的供水安全,产生供、排水矛盾。

The achievements of irrigation and rural water resources industry in China are given from the following 6 aspects: to raise output of crops,to ensure safety of water supply,to ensure safety of foodstuff,to raise income of farmers,to create opportunity of employment and to improve ecological environment.

分析中国发展灌溉的必要性,回顾农业灌溉的发展状况,从提高作物产量、保障供水安全、粮食安全、增加农民收入、创造就业机会和改善生态环境等6个方面论述了中国灌溉及农村水利事业的巨大成就,并提出提高灌溉用水利用率和效益、改善农业生产条件、解放农村劳动力、促进农业结构调整以及增加生态系统用水、改善农村地区生态环境等建议。
