Public transportation and easy commuting in the city are one of the main aspects of urban life, and taking care of a complete, regular and developed transportation system is one of the basic needs of the city. In this respect, it is important to pay attention to the principles of "spatial justice" that have been included in urban planning discussions in order to solve the inadequacies of urban management. In recent years, the city of Isfahan has experienced significant population growth and physical development in different directions. On the other hand, the results of comprehensive transportation studies of Isfahan City indicate that to provide citizens with balanced access to public transportation lines, the creation of 21 high-speed bus lines has been proposed. Therefore, the purpose of this study is to prioritize the development of high-speed bus lines by combining the Shannon, Kopras and entropy models with an emphasis on the concepts of spatial justice up to the horizon of 1410. The distinctive feature of this research is the integration of a geographic information system with spatial justice indicators in order to prioritize bus express routes for implementation. Therefore, in the first step, the status of high-speed bus lines was calculated in terms of permeability, proximity, and accessibility indicators, and the Gini coefficient and Lorenz curve of the current situation was calculated. In the second step, by calculating the Gini coefficient of each of the proposed lines separately and comparing it with the current value, the effectiveness of the proposed lines was evaluated. Secondly, the importance of the desired criteria was weighed by the Shannon entropy method. In the end, using the Kopras method, 21 proposed bus routes were prioritized for development to the 1410 time horizon. The results showed that although the Ayatollah Ghaffari terminal line to the end of Sheikh Sadouq with a length of 14.9 km is one of the medium length lines, it should be implemented considering other criteria as the first priority.

One of the most important modes of public transport is the metro transport network, which has a significant impact on reducing traffic and air pollution. On the other hand, due to the exorbitant costs of setting up the metro network, step-by-step development with the operation of one line and the implementation of other lines is of interest by urban managers. Therefore, the aim of this study is to investigate the extent of access to Isfahan metro network in the horizon of 1410 with the spatial equity approach from both horizontal and vertical aspects in 5 social classes using Gini coefficient indicators, Lorenz curve, service (supply) level index of public transportation and access. What distinguishes this research from the other similar studies is the investigation of access to the network of each metro line and finally all the lines and the estimation of population growth up to the horizon of 1410, which plays a significant role in the decisions of urban planners to develop other modes of urban transportation. The results of this study showed that Gini coefficients in access to the metro network in Isfahan in the study of horizontal equity are higher than the vertical equity, which shows a great injustice in the distribution of access of sensitive and needy groups to the metro network. So that the Gini coefficient in citizen's access to all lines in horizontal equity is 0.42 and in vertical equity in 5 classes including people over 60 years, under 15 years, without private cars, immigrants and households with an area of less than 50 square meters are 0.45, 0.49, 0.5, 0.54 and 0.6, respectively

Identify factors contributing to the spread of soil erosion, and zoning is an important tool to manage and control this phenomenon and to determine appropriate ways are to deal with spreading this phenomenon. In this research, using analysis network process model and GIS has been estimated zoning map of soil erosion in the catchment tea castle in West, East Azerbaijan Province. For this purpose, by examine the sources and expert opinion, effective factors such as slope, aspect, lithology, land use, normalized difference vegetation index (NDVI), annual precipitation and soil is provided of the geographic information system environment. Then, using Arc GIS software and extracted coefficient, the analysis network process prepared to zone map soil erosion and in five classes: very high, high, medium, low and very low. The results showed that 37.12 percent of the area that includes 118.56 square kilometers, is located in risk classes the high and very high. Furthermore, necessary to explain that in the southern and central parts of the basin is the amount of soil erosion high. These areas showed critical situations and acute erosion. And due to dam construction, Ghale Chai should be placed the priority programs and plans of soil conservation and watershed management.
