Industrial Revolution and its outcomes caused fast growth of cities and urbanization. Population and industries and overconcentration (especially metropolitans and big cities) and low quality of life on one hand and the limitations of horizontal growth on the other hand, put the strategy of building new towns as the agenda of the governments aiming to absorb population overflow and removing concentration from the metropolitans. Building new towns in Iran has begun since 1980s as a basic solution in the country's system of urbanism. Now with more than two decades of new towns activity, assessment of their Performance seems necessary. For this goal Andishe new town with population of 75596, the most populated new town within other new towns around Tehran-the country's biggest metropolitan is studied. In this research the data of Statistical Centre of Iran interviews with the authorities of New Towns Construction Company, field studies and questionnaires were used. SPSS software was used for data analysis. The findings show that Andishe new town has been successful in absorbing population overflow, gaining the inhabitants satisfaction and providing jobs.

Regarding to the guiding plans in IRAN for five decades; it’s expected that such attempts in low crowded cities land to an exact planning which be able to quarantine the development of our central cities .The comprehensive planning of cities is mostly provided to boost the standards of urbanization, to control the development of cities, to coordinate different sections of city, and also to know the influential areas of them. In this study, we try to compare comprehensive and guiding plans of Dehaghan to evaluate applicability guiding plan in terms of population, framework and other functions. The research method is descriptive – analytical. The studies showed that the applicability in terms of population which is a foundation for other functions is 70% and about 7000 people are less than suggested. Except affairs such as residential , administrative - securing, religious ,commercial , green space, road net work and agricultural ,Functions other functions have not come into reality in terms of population ,and with regard to the their probability. And this reality represents the guiding plan inability to promote development in terms of the present planning. Increasing of migration because of limited opportunities for occupation, low motivation of people for farming as the result of widespread droughts and insufficient industries in the city; are some of the factors of the urban population decrease.

Monitoring land use and land cover changes has an important role in planning and managing environment. Vegetative Zagros region, in terms of biodiversity and genetic reserves is very important. therefore, this research investigate the basic structure of Zagros vegetative landscape and then compare the northern and southern Zagros, in Kurdistan and kohgiloyeh and Boyer Ahmad provinces. For quantifying metrics related to the land use patches the analysis of the landscape metrics in combination with the gradient analysis method in GIS and FRAGSTATS was used. Results showed that the percentage of cover of sustainable land use for the province Kurdistan, is agriculture (45%), pasture (41%) and forest (12%) and for Kohgiluyeh and Boyer Ahmad, forest (45%), pasture (35%) and agriculture (12%), respectively. Generally, have Kurdistan province landscape includes the larger patches, and has simpler and more continuity, while Kohgiluyeh and Boyer Ahmad province goes toward fine grain structure.

Perception of urban development process in urban planning and management of sustainable urban development is important. In this paper physical and spatial development of Varzaneh city is studied and, after recognition of its potentials and restricts with using Boolean model and overlaying in GIS and also calculation of requisite space for the added future population optimum strategies for future development is suggested. The method of the research is descriptive-analytic and method of data gathering is documental-library. In order for completion of data and monitoring urban development of Varzaneh, we have accomplished field study and group interview with Varzaneh people. The results of the research indicated that initially urban development of Varzaneh has been was self-growing and have happened around the center of the city, but because of existing agric cultural lands. It was impossible to develop the core and the new city along with the old city has been developed (they separate from each other by the river). In new developing plans direction of development is to the north. The results also signified that not only it’s not necessary to expand the city for future development even when population are threefold rather than now but also altitudinal development of city is possible due to the free lands, urban sprawl and one- floor buildings.
