农业活动对约旦穆吉布流域水质恶化的影响[J文摘:穆吉布盆地位于约旦中部，首都安曼南部。该地区北部以Zerqa盆地和南部的Hasa盆地为界，东部延伸到Azraq和Sirhan盆地，西部延伸到死海。在山谷东部边缘的山丘上，地形崎岖，悬崖和陡峭的峡谷下降到海拔约400米低于海平面(bsl)，毗邻死海。穆吉卜盆地是半干旱到干旱的地区，冬季盆地大部分地区降雨量少，夏季气温高。本研究分析了24个水样的物理、化学和生物学特性。分析分别在雨季前后的11月和2月进行。从穆吉布大坝和穆吉布河采集了12个水样，从补给穆吉布河并从上白垩统含水层(B2/A7)排放水的泉水中采集了12个水样。根据Langguth分类，地表水表现为碱土水，碱土部分增加，氯占优势。泉水中有四种类型的水;含碳酸氢盐和氯的碱土水，含碳酸氢盐含量增加的碱土水，含氯含量增加的碱土水，含氯含量增加的碱土水。 The chemistry of the water is originated from the dissolution of carbonate rocks and evaporates deposits such as Gypsum resulted from irrigation water. The high concentrations of Na+, Cl-,SO4- and NO3- could be attributed to the high probability of water contamination from agricultural activities. The average values for total coliform were ranged from 79 to 1600 MPN/100 ml and from 1.8 to 1600 MPN/100 ml for surface water and springs, before and after the rainy season, respectively. All studied springs have total coliform values exceed the permissible limit according to JS and WHO Guidelines. According to these values, it is not surprising to find high water contamination with total coliform caused by agricultural drainage to the surface water and springs, especially during summer period. %0 - Journal Article %I - %@ - 0125-895
