It can also improve the chaotic scenes so that the importance of the intuitive user and its compatibility with the environment should be balance and obviously it to unite the city's landscape and visual composition is necessary. Thus there is a need for existence of parks and green spaces as an existence needing of communities for improve quality life of people living and as a major factor increasing a good balance in the environment should be the top priority in urban planning development. Noorabad City has been flourishing in this research study. The time now is facing a severe shortage of urban green spaces. This research wants to consider and analyze the green space land use of Noorabad city with contributed existence analysis in GIS And finally locate new green spaces, however small step to be taken to solve the problems of city's green spaces.   2- Methodology  The research method used is descriptive analysis, That use city map with scale of 1/5000 through a detailed study of the city and the observed field Collect the required information using GIS software and to help analyze hierarchical Data processing and analysis were performed according to the standards of urban planning and in the end will determine the appropriate location for urban green space.   3- Discussion  Consideration of green areas of the Noorabad city frequented that area of green space is 302,061square meters that this is include rate of about 1/6percentage of legal limit of the city. The city's per capita green space isalso5/8square meters. Therefore, the need to locate a new green space for the city should be felt. In this survey to locate new green space has been used from Layers of this information: 1) Proximity to Training centers 2) Distance from existing urbanparks3) proximity the center of the area 4) Proximity to residential centers5) Proximity to cultural and sport centers 6) Distance from troublesome user7) Distance from the main network 8) Access to sub Network 9) Located in the Good Land use.  Next, we discuss the value of information layers, giving the value of the parameters is done in, Expert Choice software. First, the criteria and sub-criteria in the site selection of urban green space were determined. Then paired comparison matrix formed .Then criteria and sub-criteria are compared to two barges. After obtaining the relative weights of criteria and sub-criteria, The final weight is obtained by multiplying the values in sub criteria then with Enter final weight to data table's the criteria for location information maps from this tables were generated.  After determining the weights of criteria and sub criteria, consistency in judgment was investigated. If the consistency index be less than or equal to 1/0 consistency in judgments is accepted.  Otherwise, the judgment should be revised. The following table shows the information criteria rating:  Name of standard  Proximity to cultural centers  proximity the center of the area  Proximity to residential centers  Distance from the main network  Proximity to sub Network  Distance from troublesome user  Distance from existing urban parks Proximity  proximity to Training centers  land use  privilege  0.063  0.114  0.107  0.107  0.128  0.068  0.124  0.062  0.234    After determining the weights of criteria and sub criteria turn to enter the weight and composition of the GIS layers appears. The process of composing the layers using index overlay model were carried out that. Finally the studding area in terms of creating new green space is classified into seven categories. In the next phase of site selection pattern matching can be done with ground realities. In This study determining the optimal location in the GIS software these locations were observed field. Finally the model results match the actual location of the study area and considering all the parameters affecting the site selection process and the amount of land needed to create an urban park finally found many place to create new green space (below shape).   4- Conclusion  Although green space as one of the indicators of sustainable urban development and be remembered, the criteria for recognition of Healthy City. But its lack is felt strongly in the city Noorabad. And spatial distribution of urban parks Noorabad this reflects the low number of parks in the city and its distribution is unfair. So that in most parts of the city center. We have the most coverage. While in other parts of the city are faced with a lack of green space. Thus the need for proper planning to solve the current problems of the city's landscape is felt also results of this study indicate Effectiveness of GIS in urban planning, especially in urban green areas location.  Keywords: urban parks, Geographic Information Systems (GIS), Noorabad city, location, spatial distribution.   References  Ale Sheikh, Aliasghar & Helali, Hossein& Soltani, Mohammad Jafar (2002): GIS application in the areas of Flood, Journal of Geographical Research, number 4, Isfahan.  Bijanzade, moohamadreza (1990): Discussion green spaces in Tehran, office of university jahad.  Esmaili, Akbar (2003): Applicationof gis at the fire station routing process, traffic updates, year 4, number 19.  Farajzadeh Asl, Manucher (2005): GIS and its application in tourism planning, Samt Publishing, Tehran.  Haidari Bakhsh, Marziah (2008): A comparative study of standard city park and green spaces with existing standard, m.a.thesis geography and urban planning, Isfahan University.  Hekmati, Jamshid (1992): design garden and park, jame Publishing, Tehran.  Hekmati, Jamshid (1995): The trees along the streets, giving a second life, garden journal, number 9-10.  Hossein Zade, Karim (1992): comprehsive planning and design of urban green spaces for parks, journal of geography.  Majnonian, henrik (1993): Debates about the parks, green vfzay and resorts, tehrans parks and green space, tehran.  Mohandesin, moshaver, EMKO (2004): Detailed design of noorabad.  Ngai, E, W.T.E.
