Quantative status of Mashhad urban arboreal green space and investigation on its possibility developing using WLC method and GIS

Due to the lack of comprehensive planning at the national level¡ urban services uses among green space have encountered problems such as deficiency of green space per capita¡ inappropriate distribution and location and lack of prediction of this spaces in cities. In this study¡ for the first part: Using GIS capabilities¡ arboreal green spaces per capita¡ including parks and gardens planting trees and tree stands can be used for public¡ in different regions of Mashhad¡ evaluated using satellite images and regions were prioritized in terms of per capita. The results showed that region 3 has the lowest arboreal green space per capita. In the second part: Locating of urban forest park¡ with considering its criteria on aspects of recreational¡ ecological and structure were investigated. In the first layer data maps were produced¡ then standardized using various fuzzy functions. Then the standardized maps multiples own weights got from AHP¡ and were combined using WLC method. Result maps¡ showed suitability of Mashhad region 3 lands and the most appropriate sites for creating of urban forest parks. The results showed that barren lands and agricultural lands¡ respectively¡ have much suitability compared to other land use because of the ease of conversion to urban forest parks. Also areas that are closer to the city center¡ have a high suitability for creating an urban forest parks¡ because of the proximity of residential¡ education¡ tourism and recreation uses and also the ability to create boundaries and privacy¡ and improve the quality of urban areas and proximity to air and noise pollution sources. From the results of this study can be used future projects and plans related to the construction of urban green space according to the criteria and area potential.
