Abstract
Livestock farming is one of the most important activities in rural areasand most villagers, along with agriculture and horticulture, are engaged in animal husbandry (Livestock storage) and some products of the villagers in the agriculture and horticulture sector are devoted to livestock feeding, and others are consumed or sold, such as lob bits, live meat and etc. The purpose of this research is to analyze the effects of livestock economics on sustainable rural development. The present research is applied in terms of purpose and is descriptive-analytical in terms of its nature and method. Library and field studies have been used to collect data. The study area is East Gavdoul District in the Malekan County. According to the census of this region, there were 2306 households and 7468 inhabitants in 2016. According to the Cochran formula, 283 households were selected as the statistical sample of the research. This sample was randomly selected from households with livelihood economics. To analyze data on inferential statistics, one-sample t-test, regression, analysis and performance diagrams were used. The results of this study showed that there is a positive and meaningful relationship between livestock economy and sustainable rural development with a correlation of 0.400 and significance level of 0.30; So, for the dimensions of livestock economics, the economic sector with the impact of 0.743 and the social sector with the impact of 0.355 have the most impact on the sustainable rural development in the region. Also, the physical section with an impact value of 0.176 has had the lowest level of impact on sustainable rural development in the region. The general results of the research show that the economic sector with 0.41% and the social sector with 0.31% have a positive effect on the development and expansion of th
e livestock economy of the area.

Abstract
The purpose of this study was to evaluate the temporal variations of vegetation cover of Gharesou River riparian area in Ardabil province using landscape metrics over a period of 8 years which is important for morphology assessment and river ecosystem protection planning and management. The Google Earth imagery for the years 2011, 2016, 2019 due to their live view and high resolution were used to map the Gharesou River riparian area vegetation. Correlation analysis in R environment was used to evaluate the relationship between landscape metrics in the study time period. The results showed that there is an increase in the number of patches, which showed an increase in landscape fragmentation of the riparian area vegetation. Landscape connectivity index was 91.52% to 95.49% in this region during the study period, indicating the removing small patches of vegetation communities around the river. The number of patches in the present study showed an increasing trend, which was the highest amount at 2019 year. The results of changes in the width of the Gharesou River showed that the river width in 2019 was 27.43m and 3.97 m, respectively. Comparison of river width values over the three study periods indicates an increasing trend in river widths, which may be due to the limitation of river width by human activities or the protection of river banks to protect agricultural lands against flooding effect. Also, the correlation of river width showed that the correlation between time period 2019 and 2016 was 0.63 and significant at 0.001 levels. The lowest correlation between the period 2019 and 2011 was 0.30 at 5% significant level. In conclusion, the results of changes in riparian area communities can be linked to the extension of agricultural land adjacent to the main river course.
