تغير الغطاء الغابي في حوض وادي كفرنجة-الأردن للفترة بين 1978-2010 باستخدام تقنية الاستشعار عن بعد و نظم المعلومات الجغرافية

الملخص EN

The purpose of this study is to detect, analyze and explain the change in the forest land cover in Wadi Kufrange Basin / Jordan during the Period 1978-2010.

To achieve these goals, Geographic Information system (GIS) and Remote Sensing (RS) techniques were used by analyzing aerial photographs cover of 1978, and satellite image from web-link of Google earth 2010.

It was apparent from the study that : -The forested area in the basin increased from 16.9 km² in 1978 to 23.4 km², in 2010 (its proportion increased from 13.38 % to 18.53 % from the total area of the basin).

The increases in forest area through afforestation between 1978 and 2010 was 6.5 K.

m², or 5.15 % of the total area of the watershed.

-0.5 km²of the land across the watershed has been converted from forest cover to build up area, 6.2 km² to agricultural land, 0.15 km² to rangelands.

3.45 km² of barren land and 9.4 km² of rangelands converted to forest land through afforestation.

-There is always high probability of conversion of forest land to another type of land cover and land use.

Barren lands suitable for afforestation is about 6.6 km², where slope ranges between 13º-20º, 20º-55º, and rainfall ranges also from 300 to 400 mm.
