iabadi, Ali | Fathi, Effat | Izadi, Mallihe
Today, the development of agricultural industries, especially small and efficient agricultural sector has been paid more attention. The development of rural industries in the country led to job creation and absorption of surplus labor force in agriculture and also resulted in more exports and foreign exchange. This paper evaluates development indicators of process industries and accesses to regional inequalities in the cities of Isfahan province. The research method is descriptive-analytical. This paper tries to examine the process industries associated with agriculture in Isfahan province. Therefore, statistical data was collected and processed by SPSS and Arc View. The status of Isfahan process industries was analyzed using PIDI (Process industry development index) in order to grade the city industries conditions so that we can propose more desirable planning for optimal process industries and the processing of agricultural products. The results show that the eastern cities of the province are disadvantaged in terms of this index and are considered as the first priority in order to develop appropriate measures. The second level includes western and southern cities that are the second priority for the development. Last level of development has been drawn linearly from North-West to South-East and the final priority is allocated to this level.

Ahmadi Sani, Naser | Babai Kafaki, Sasan | Mataji, Asadllah
Zagros forests are a treasure of various valuable species of oak in Iran and the world. Long-term misuse in the past has caused severe degradation in the Zagros forests. Recently these forests have become national but misuses by local people to make living because of poverty and unemployment are continued. In order to reduce degradation and improve sustainability, ecological capability for extensive ecotourism was assessed using multi-criteria decision-making (MCDM), geographic information system (GIS) & remote sensing (RS) in 9150 hectare of Baneh forests. The ecological criteria and sub-criteria affecting the evaluation were selected based on the literature and expert choice. The criteria and sub-criteria were weighted using the analytical hierarchy process (AHP). Sub-criteria were mapped on 1:50000 scale using available maps, field work and IRS-P6 satellite data. Then sub-criteria maps were classified and classes were scored according to literature review and expert judgments. An extensive ecotourism priority map was created using GIS-based weighted linear combination (WLC) model by MCE analysis. The most important criteria of extensive ecotourism in study area were water resources, landscape and climate. Of the whole area, 450, 7883 & 817 hectare were in 1, 2 & 3 priorities. According to compatibility of extensive ecotourism with present land uses, it can exist in the whole parts of study area ecologically. In addition, this study demonstrated the potentiality of integrating MCDM, GIS and RS techniques for resource allocation in ecotourism planning.

In the early years, the rising of the sea level, which is a part of natural treatment, destroyed many buildings, arable lands, residential and commercial areas. It seems that the main reason of these destructions is the diminishing of the legal setback efficiency and the proceeding of human activities. The aim of this study is to introduce the appropriate setback for southern coast of Caspian Sea (Gilan province) on the basis of critical levels of Caspian Sea and the results of coastal vulnerability regarding sea level rise. This setback is composed of two parts, vertical buffer and horizontal buffer. In this study, CVI method (coastal vulnerability index) was used for coastal vulnerability assessment. In this method, five variables were employed as in two sub-indexes, natural and human-induced sub-indexes. The final map is divided into four categories, from low to very high vulnerability. Finally the mean distance from the very high vulnerability category to vertical buffer boundary in every district is introduced as the horizontal buffer.

Nowadays because of various factors, including inappropriate land use, and indiscriminate exploitation of water resources, soil and vegetation, wide areas of the country were exposed to destruction of lands and desertification. Therefore dealing with this situation requires a comprehensive land use program (water and land) and appropriate environment potency. The study area is Patom district of research-educational forest in natural resources College of Tehran University, which is called kheyrud forest. In this research, the map of environmental units was prepared in which each unit contains different ecological condition from adjacent units. Moreover, the information of less stable resources of ecosystem was prepared and then the process of land capability determination was performed using specific models which were extracted from Makhdoum models. The results declared that this district of forest with attention to the work scale (1:10000) has management capabilities for harvesting, protection and ecotourism. To move towards sustainable development, providing the community needs and various expectations of natural resources, forest management should pay attention to the multiple use of forest with regarding to the ecological potency of region

Ecological capability evaluation and landuse planning can determine the best landuses and are important for the proper planning and sustainable development. There are various methods for ecological capability evaluation. In this research have been studied two methods (Land use planning method with Makhdoom ecological modsels) and (Geomorphology method) for ecological capability evaluation in Nesa watershed. This region is located in Hajiabad district of Homrmozgan Province. These methods have been compard. Results show that these two methods are relatively similar for this watershed and landuses for the most of this region are poor range management and conservation. According to Geomorphology method, 60% of this watershed is suitable for conservation and 50% of this watershed is suitable for poor range management, also according to Land use planning method method, 55% of this watershed is suitable for conservation and 47% of this watershed is suitable for poor range management. But preference of Land use planning method is determining of various landuses such as tourism, civil, rural and industrial development that helps to planner for the proper planning and management.

Ardakani, Tahere | Dane-kar, Afshin | Erfani, Malihe
Every time a visitor sets foot in an ecotourism site, he/she causes a negative impact. this is an unavoidable fact. an ecotourism program initiates many public use activities that will have impacts ,both positive and negative. an Ecotourism Management Plan seeks to minimize the negative impacts.therefore monitoring and managing of visitor impacts are fundamental ecotourism management strategies. If you do not know what effects your ecotourism activities are having on the sites natural environment and the surrounding communities, then you cannot say that you are successful. Monitoring costs General Management Plan and requires trained personnel and assistance of interested stakeholders. The first methods developed to address tourism impacts evolved from the concept of carrying capacity. the more simple concept of carrying capacity-limiting numbers of visitors- can sometimes be used as a solution for mitigating impacts in restricted, small-scale situations .in the survey ,disrupting objects, such as carrying capacity and monitoring of visitors activities.

Nasiri, Alireza | CHehraghani, Abolghasem
Nowadays, spatial spread balance in resources and utilities between cities is one of government aims. Utilities spreading balance is binded to their sites in order to all people can access them easily. On the other side, Land Surveying's main goal is regulating human activities in national environment to reach rational exploitation of resources and land capabilities. This goal could be accessed via GIS and its ability in various contexts. In this paper, we focused on spatial spread of Gas industry infrastructures, especially CNG stations in Qom province. First, we evaluated existing CNG cites. We designed special questionnaire containing questions about CNG station's quality, quantity, spatial and services. The forms were filled with drivers and we analyzed them. Also we used GIS to implement CNG cite standards and analyzed existing stations. Also we determined optimal places for CNG station using GIS. Our model includes AHP for weighting layers, a way that uses comparative methods for weighting, and Index Overlay for combining layers with AHP weights. Finally, we categorized Qom province in six categories ranging "Very Unsuitable Sites" to "Very Suitable Cites" for CNG station.
