Evaluation of infill development capacities with Emphasizing on infill Development Strategy in the Case Study of Ardabil City

Cities to expand on their peripheral surroundings, regardless of the various physical, environmental, social and economic impacts. development is one of the new strategies to counter the physical development of cities. The main purpose of this strategy is to recapture lost or destroyed urban spaces. The type of research is applied -Practical and its method is analytical. Shannon and Holdern's entropy coefficient method to analyze the data and information for measuring the sprawl of the city, the nearest index for the model of infill development capacity distribution and the Vikor model for ranking the urban areas according to the studied land uses was used. According to the Shannon entropy coefficient calculations, the value of ln (n) is obtained at 1.38, which indicates that urban sprawl and physical development are sparse compared with the urban entropy coefficient of 1.37. Holderen's results also show that about 90 per cent of the city's growth was due to population growth, and only 0.09 per cent was to the city's horizontal and spiral growth. A comparative study of the proposed area and the urban area surveyed reveal that approximately 917 hectares of proposed landfill levels have not yet been met. While the city's infill capacity is 2408 hectares. By comparative comparison, the area is measured at a numerical average of the nearest-neighbour ratio of -27.58. Since this value is smaller than one, we, therefore, conclude that the inner city capacities are clustered throughout the city. Finally, according to the results of the Vikor method, region 3 has the highest infill development capacity with 36.15.
