Abstract

Climate change with changing climate patterns and confounds Ecosystems discipline, imports Serious consequences on the environment. Changes in weather patterns Could lead to severe flooding, extreme heat or cold, more frequent droughts. Each of these phenomena could Put at risk the regional food reserves. North east of Iran due to the large area has very varied natural conditions and each of the areas included specific natural features. The extent of the area and factors such as mountains rising, desert areas , stay away from the water zones and different winds lead to variety of weather in each of those area. Based on the results if the man-kendall test and AHP model in north east of Iran, climatic elements with ascending trend (82.25%) much more than climatic elements with descending trend (35.5%) affect on climate change in north east of Iran. Areas that experience most climate changes due to descending elements (number of frost days , average moisture, the number of days with snowfall,24-hour rainfall, annual precipitation) is seen in the South and South east of region. Climatic elements with ascending trend (The average temperature, the minimum temperature, the maximum temperature, hours of sunshine) cover most extent of this region. Only Ghochan and Sabzevar stations demonstrate the least climate changes.
