Promotion of urbanization is one of characteristics of current societies that in their evolutionary trend results in establishment of megalopolis and brings the complex urban management in these huge population centers every day, together with new difficulties. Urban environmental problems, providing public and security services, green space and city fa ade, urban economic problems, informing, research and training makes the urban management duties list every day longer. Tehran Metropolis as the most important and greatest city of Iran and one of the most important metropolises of Middle East and included in the 20 great cities in the world, face these challenges more and less. Doubtless, management in this city with a population of 8 million peoples and 2/3 million families residing therein in an area equal to 800 square km, is not possible without participation of citizens. Citizens&rsquo participation in their city and neighborhood matters, firstly has frequent benefits for municipality. If citizens based on their well-known motto &ldquoour city, our home&rdquo are sensitive to the city matters and public profits, then plenty of municipality responsibilities will be fulfilled in a better manner. Therefore, quality of assistance to the growth of organizational model of urban NGOs&rsquo participation has been converted to an important phenomenon and one of the most essential questions. The experience of participation of NGOs in the developed societiesindicated that solving many urban problems such as urban environment, inappropriate status of security, unsuitable city fa ade and improper urban economic status is possible only at the extensive presence of NGOs and upon active participation and responsibility in the urban services management. Despite of awareness of necessity of development of NGOs participation in the urban matters administration, this concept in its organized concept in each one of participation levels encounters a lot of barriers such as deliberation, commenting, proposing, decision making, planning, execution and supervision on urban projects which limits the opportunity of NGOs upward from participation stair.Objectives of this research: Identification of grounds of need to citizens&rsquo participation and identification of citizens&rsquo participation promotion that upon studying national documents in national context (including constitutional law, viewpoints of supreme leader of Iran, 20-year perspective document of regime, fourth and fifth socioeconomic and cultural development plans and policies applicable on sixth development plan), and in urban context and comparative urban study in foreign cities consistent to Tehran, based on comparative and focal studies, at first strategies for promotion of NGOs&rsquo participation in urban services are presented. Later theoretical model was offered for formulation of strategies for NGOs&rsquo participation promotion in urban services management.

Iranian formal censuses indicate that the share of rural population in total population of Iran have been decreasing over the time and many villages are uninhabited. Migration statistics in Iran have also indicated intense migration from villages to the cities during the past half- century. Many researches have been conducted due to the importance of rural-urban migrations, during the past few years. Therefore, the main goals of this study are to criticize and evaluate the written articles using meta-analysis method in rural-urban migrations field and to identify the most important factors affecting rural-urban migrations, widely used theoretical approaches in this area and etc. The findings of this research show that attraction and repulsion viewpoint and Michael Todaro&rsquos theory are appropriate theoretical approaches to state the problem of rural-urban migrations in Iran. Also, urban attraction variables with impact size of 0.75 and occupation with impact size of 0.62 have the most effect on rural-urban migration. Other findings indicate that the most solutions proposed in the reviewed researches are general, vague and non-executive and there is no proportionality between the proposed solutions and the study objectives in most cases.
