以色列位于水资源短缺的沙漠地带边缘,其北部3～6月份的降雨量为60～100亿m~3/a,60%立即蒸发掉。每年约有18亿m~3的水以洪水和沟壑径流的方式流进地中海和死海,约有35%渗进土壤表层,其中一半补充进地下含水层,另一半也失掉了。以色列每年平均获得水量17亿 m~3,而使用量却比该值大3亿m~3,每年的不足额累积起来已达到20亿 m~3。近年来由于用处理后的污水灌溉农田,修建水库拦截径流洪水和抽取地下水,使缺水情
Israel is located on the fringe of water-scarce deserts. Its rainfall in the north of June to June is between 60 and 10 billion m 3 / a, and 60% of its rainfall evaporates immediately. Each year, about 1.8 billion m 3 of water flows into the Mediterranean Sea and the Dead Sea by means of flood and gully runoff. About 35% of the water seeps into the soil surface, half of which is recharged into the aquifer and the other half is lost. Israel gets an average of 1.7 billion m 3 of water per year, but its use is 300 million m 3 more than that. Israel’s deficit has accumulated to 2 billion m 3 each year. In recent years, due to the use of treated sewage irrigation farmland, build reservoirs to intercept runoff floods and extraction of groundwater, water shortages
