摘  要：
渤海湾滨海盐渍土地区农业咸水利用包括咸水直接灌溉(混灌、轮灌等)、咸水结冰灌溉及咸水冰、海冰覆盖灌溉,但均不能满足可持续农业的要求。通过分析当地农业生产需水及风能、太阳能年内分布特征可知,渤海湾滨海盐渍土地区农业生产需水关键期恰好为风速最大、日照时数最长季节,这可为当地结合丰富浅层地下咸水,利用反渗透淡化设备解决当地农业用水提供充足的清洁电力供应。

摘  要：
Apart from the precipitation,the existing agricultural water problem was solved by extracting fresh water from deep underground and using underground salty water resources including saline water irrigation(mixed irrigation,rotational irrigation),freezing saline water irrigation and salty-water ice,sea ice cover irrigation along the Bohai bay coastal saline land area.However,the current resources usage modes could not meet the normal agricultural production needs in local area.From the analysis of water demands of local agricultural production and the distribution characteristics of local wind and solar in study area,the season that was in the critical period of the agricultural production water demand had the maximum wind speed and the longest sunshine hours,which could provide adequate supply of clean electricity for the reverse osmosis desalination equipment to satisfy the local agricultural water demand combined with rich shallow underground salt water in the local area.
