Influence of New Cities Population on Nodes in Spatial Organization of Rural Settlements (Case Study: Molekabad City, Mashhad)

Pages 1-32

From the view of rural planning, the creation of optimal rural hierarchies and centers prevents "decentralized concentration" of growth centers and "centralized concentration" of inequality between regions. Ignoring the effects of economic policies has led to unintended spatial effects that have led to imbalances in the distribution of facilities and a tendency to focus. Economic and social developments diversify city-village relations and change their interrelationships. Early views consider the role of new urban centers in rural development in modern patterns and permeate modernization into rural settlements. Attracting investments, communication flows, etc. to new cities makes agricultural and garden lands out of the economy and coveted by urbanites, and the resulting changes form a new space organization. Changes in this organization should not lead to new non-rural landscapes. In the opposite direction of villages, decentralized concentration is created, leading to stability, distribution of population in nodes. The spatial organization of the village has a definite territory and includes a mixture of form and rural activities. In this article, Molekabad is considered and its information is from library and a questionnaire and the research is descriptive-analytical. The Likert questionnaire and each item with its mean and standard deviation and level of significance are examined in the K2 Test. Statistical tests used for data analysis, based on Kruskal–Wallis Test, data with a sample size of less than 30 reach non-parametric results. In the Kolmogorov–Smirnov Test, the sample size is less than 30 and the null hypothesis is defined to prove it. In the theory of creating new cities, the development of nodes is questionable. As a result, the creation of settlements and the life and development of villages depend on the added value of the agricultural sector and the natural landscapes in the population of villages with the creation of second homes, which will not be universal everywhere.

Analysis and forecasting of heat waves in selected cities in Northwest of Iran

Pages 76-89

Heat waves are one of the most important weather disasters, and their destructive environmental effects require knowledge and forecast. The purpose of this study is to forecast the future conditions of heat waves in Ardabil, Tabriz and Urmia during the years 2020-2050 using SDSM downscaler and Baldy index. For this purpose, the maximum daily temperature data of selected cities from 1961 to 2005 after preparation were entered into SDSM software and analyzed with CanESM2 model with 2٫6, 8٫5and RCP 4٫8 scenarios and with the output of the model, the maximum temperature trend of the three stations during the next 30 years was investigated and their heat waves were Forecasted using the Baldy index. According to the results of the error measurement of the model, the simulations performed had acceptable accuracy. Due to the fact that each of the cities showed the least error in one scenario, so the heat wave prediction of each station was done using the least error scenario. Based on the results the average maximum temperature will decrease from late winter to late spring compared to the base period and will increase slightly in mid-summer. In general, we will see a decrease in the average maximum temperature in Ardabil and an increasing trend of the mentioned parameter in Tabriz and Urmia cities during the years 2020-2050. Also, the study of the predicted heat waves in the next thirty years showed that one-day waves in Ardabil and Urmia will be a slight increase and in Tabriz will be almost without trend. Two-day heat waves will decrease in Tabriz and Urmia and will increase in Ardabil. The trend of three-day heat waves in Ardabil and Urmia will be decreasing and increasing in Tabrizthe highest continuity of heat waves was four days, which was forecast in Urmia. The highest frequency of two- and three-day heat waves in all three cities will be in the cold seasons of the year.

Social and Economic Impact Assessment of Second Home Formation in Zardanjan, Isfahan

Pages 90-105

Post-World War II global developments, such as the expansion of urbanization and the creation of large cities, the pollution of the urban environment, as well as the increase in leisure time, led to the expansion of rural tourism, especially second home ownership. Today, the tourism sector as a productive sector plays an important role in generating income and creating jobs in the economies of the countries. As such, many countries look to the dynamic tourism industry as a major source of income, employment, private sector growth and infrastructure development. One of the essential strategies for the development of rural areas is to pay attention to rural tourism to isolate and marginalize rural areas. The purpose of this study was to evaluate the socio-economic impacts of developing second homes in Zardanjan village of Jay village. The research method in this descriptive-analytical study is that the statistical population of the study is Zardanjan village households and Cochran method was used to determine the sample size. Sample selection was done using random sampling method and 87 people were selected as sample. Library and field methods and questionnaire tools were used for data collection. For data analysis, t-test was used. The findings showed that the expansion of construction of second homes in Zardanjan village due to factors such as proximity to Isfahan, increased leisure needs and the need to relax in a quiet environment. The continuation of this phenomenon has had various consequences in the rural areas, the most negative of which is the destruction of agricultural land and rising land prices and sociocultural instability and the most positive consequence of increasing diversification of economic activities especially in the service sector and achieving economic sustainability.

Measuring and evaluating urban viability in the neighborhoods of Cayenne

Pages 174-198

The growth of urbanization and the desire to urban environments have increased the importance of the concept of quality of life and urban viability, and the replacement of quality approaches instead of paying attention to general standards has led to issues such as urban quality of life and urban habitability. The habitable city is not only about meeting physical needs, but also to satisfy the public's satisfaction with the city. The purpose of this study is to investigate urban bioavailability in the neighborhoods of QAENTo determine the sample size, the Cochran formula was used for calculating 381 questionnaires for the population of 42323 people. Then, to each of the urban neighborhoods, based on the population size, the proportional quota was determined. The results of the data were analyzed using the software, ARCGIS, SPSS model The analyzes of GWR and WASPAS were analyzed. The results of the research show that among the neighborhoods in terms of the overall weight index, Azadegan neighborhood having the highest weight (0٫419) was ranked first in terms of having the indicators of viability and satisfaction level of citizens, which indicates the desirable condition of the neighborhood. On the other hand, the Kawi Beheshti neighborhood with a weight of 0٫216 is low in the neighborhood level in terms of having indicators of citizens' survival and satisfaction, which indicates the unfavorable situation of the neighborhood in the city of QAEN. . In other words, it can be analyzed that in the neighborhoods of the city of Cain, living standards that show a better quality of life are more favorable in the Azadegan neighborhood. On the contrary, in the neighborhood of the Kufa Paradise, where living standards are minimal, there is an unacceptable livelihood for its inhabitants.

The role of medicinal plants in the development of rural settlements with emphasis on job creation (Case study: villages of Kalat city)

Mansoureh Alipour Khesht, Hamid Jafari, Katayoun Alizadeh Pages 198-212

Diversifying the economy of rural settlements in developing countries has improved non-agricultural job opportunities in rural areas and also has a significant impact on the well-being of rural households. Studies show that the diversity of economic activities has an effect on the economic sustainability of rural settlements, which means that the greater the diversity of economic activities, the higher the economic sustainability. Today, medicinal plants play a vital role in advancing national, regional and global goals to achieve health, environmental protection, selfsufficiency, job creation, entrepreneurship and economic development. Therefore, the present study aimed to investigate the effect of cultivation of medicinal plants on job creation in rural areas (case study of villages in Kalat city). The present research is applied in terms of purpose and descriptive-analytical in terms of method. The sample population includes 7 villages of Kalat city in which medicinal plants are produced. According to the research results, planting each hectare of medicinal plants creates an average of 1.301 percent more jobs compared to other crops.

Measurement of Guilan Vulnerability to Drought with GAMA and SUM FUZZY Models, AHP

Pages 213-229

In Iran, low rainfall along with inappropriate temporal and spatial distribution has caused droughts. The aim of this study was to measure the vulnerability of Guilan province to drought with fuzzy GAMA and SUM models, AHP. The research method is spatial analysis and applied in terms of purpose. First, the components of climatic vulnerability were determined, which were the rate of discharge of springs and wells, surface water, rainfall, temperature, amount of agricultural land, population of different parts of the study area. The variables were matched with fuzzy membership functions and overlapped with GAMA and SUM models. AHP model was also used to weight the variables. The results showed that from the point of view of experts, the importance of precipitation parameter with a weight of 182.0 is the highest and the parameter of agricultural lands with a weight of 18157 is the lowest. The weight of groundwater discharge parameters, surface water, population, temperature in pairwise comparison were 18267, 18.1, 18122, and 181.6, respectively. AHP zoning is the highest accuracy and GAMA and SUM models are the next priority. AHP zoning showed that the middle part of Rasht, Saravan, Kasma, Anzali and Shanderman provinces had the highest drought and the west of the province including Hashtpar and Astara with an area of 37833 in the next stage and then Samoosh, Shalman and Lahijan with an area of 203 and finally some parts. From the north of Astara, south of Rudsar city and south of Rudbar, Darfak heights with an area of 33873 have experienced the lowest drought. In the SUM model, the highest vulnerability was in the west, center and large areas of the east of the province, Rudsar city with an area of 7.8233. In the GAMA overlap model, large parts of the west of Talesh city and Rasht city with an area of 318023 were observed in a very high vulnerability class. Investigating areas that are experiencing more and more severe droughts and focusing more on those areas will lead to better resource management and can reduce the damage caused by drought.
