Abstract:
تعد مشكلة الملوحة من اهم المشاكل البيئية المعاصرة التي باتت تهدد الانتاج الزراعي والانسان وتحد من نشاطاته وتطورها في الوقت الحاضر والمستقبل مما يتطلب الحد من تاثيراتها للحفاظ على مفردات البيئة، ونظرا لان هذه المشكلة اصبحت لا تقف حدودها على منطقة معينة او | The problem of saltiness is the most important problems in the contemporary environment which threatens the human beings and reduce their activity and its development now and in the future so we have to reduce its effects to protect our environment. Since this problem is not found only in this place or this country and its effect begins to appear generally in our country and specially in the area of the study , We choose this subject to the causes of this problem in the are of the study now and in the future. The climate in the area of this study is dry and semidry which is accompanied with different properties of soil and water and many problems which lead to the decrease of agricultural production and agricultural lands. In addition the use of different ways in irrigation, the bad quality of the systems of drainage canals and wide areas of agricultural lands are left as a waste land and not exploited. As a result there is increase in the salty lands and the expansion in the summer agriculture. All these elements help to expand and differ the appearances of saltiness in the area of the study. We depend on the statistics and the available information's and also we use maps and space photos to reach the Remote sensing for the salty areas and its geographical contribution. We put the successful solutions to reduce the effects of this problem depending on the international and Iraqi experiences which have been applicated to cure this problem and stop its effects on the environment now and in the future
