Gongye shui chuli, 1986 淡水资源的紧张是世界性的问题,而沿海工业城市尤为最甚。一般说来,城市用水的80%是工业用水,而工业用水中的80%左右是工业冷却水。因此,对沿海工业城市来说,节约城市用水最有效的方法是利用海水代替淡水做工业冷却水。但是,海水对金属设备有极强的锈蚀力,尤其是弯头处更易锈损、一台价值三十万元的快速冷却器,使用半年就得报废。此外,水中生物诸如贻贝、牡蛎,藻类等附着在管壁上越长越多,堵塞管路,不得不停产铲除,日用海水量达50万吨的大连化学工业公司每清理一次海水输送管路,仅贻贝(俗称海红)就拉走四十卡车。由此看来 ...

Shuitu Baochi Xuebao, 2017 为定量评价托木尔峰自然保护区森林的水源涵养能力，利用综合蓄水能力法，对台兰河上游雪岭云杉森林生态系统的林冠层截留量(C)、枯落物持水量(L)、土壤层蓄水量(S)及综合水源涵养能力进行估算和分析。结果表明：（1）研究区4样地中，林冠层截留量表现为中海拔云杉林（29.94 mm）>较高海拔云杉林（20.56 mm）>高海拔云杉林（11.72 mm）>低海拔云杉杨树混交林（5.84 mm），而茎流量则与之相反。（2）除中海拔云杉林外，各样地枯枝落叶未分解层平均厚度均大于半分解层；其中 ...
