The results show that the studied concentration in muscle tissue of blue swimming crab (Portunus pelagicus) at sample locations statistically significant difference shows. Also studied in terms of concentration in the muscle tissue of blue swimming crab in the study area between summer and winter statistically significant difference was observed (P < 0.05). As both in summer and winter concentrations of lead, nickel, iron and copper in muscle tissue of blue swimming crab in Qeshm is greater than the other two regions. Meanwhile, the results of the study compared concentration in muscle tissue showed blue swimming crab with international standards. The studied concentration in muscle tissue of blue swimming crab in Qeshm, Khamir port and Laft port international standards is less than the limit. Which indicates that the health of aquatic ecosystems contamination is not a problem.

All rights reserved. 2 Abstract The new concept and yet the old one about conservation with the contribution of indigenous people and local communities has attracted many scientists’ attention. International conservation policies and programms recognize and support indigenous and community conserved areas and encourage all states to do the same. This thesis aimed to introduce marine and coastal Indigenous and Community Conserved Areas and the related laws, regulations and development plans thoroughly in Iran. The main focus of this thesis is on traditional conservation by local communities in Qeshm Island, located in Hormozgan province in south of Iran along the Persian Gulf. Through this study, it was concluded that indigenous people and local communities have an important role in governing protected areas and it is recommended to include them in conservation programms. 3 SUPERVISORS: Dr. Anthony Charles Dr. Francois Bailet Ms. Valentina Germani 4 Acronyms CBD Convention on Biological

The geometry of this architecture is the result of its fundamental components and elements not being formed in the designer’s mind all of a sudden in a constructive and unified process; rather it is the result of a gradual practical and constructive method. Its components including physical and geometrical features exert significant effect on the end result of the overall volume. The formation process in nature is often carried out by the help of a structure or some structures. Like nature, formation of volumes in Iran’s traditional architecture follows the same rules. The morphologies of the traditional architecture as well as the modern architecture are fundamentally different with each other from this perspective. This means that the former is accomplished through motion of basic, constructive and standardized elements in space while the latter is realized through a mental and abstract process.

[email protected] ABSTRACT Qeshm Island is one of the most beautiful Islands in Iran which has gathered a worldly unique and precious collection due to its eroded phenomena (i.e. Chahkooh canyon, Stars Valley and Tang-e Ali Strait); valuable geological heritage (i.e. Namakdan Salt Dome the world's largest salt cave and etc.) and cultural and historical diversities. This Island is of particular importance in national and international fora due to the aggregation of these attractions, being located in the strategic region of Persian Gulf, being the first geopark of Iran and the Middle East and being known as the eroded land, it also can be called the geotourism gateway of Iran. In this paper along with introducing the theoretical concepts, geographical and geological features; ecotourism and geotourism potentials of Island, the impact of erosion on the creation of amazing geosites were also studied in this Island and solutions were offered for the development of geotourism. The research method in this paper was descriptive - analytical and data collection was done through library research, field studies and satellite images.

  • Three-Dimensional Simulation of Qeshm Channel Currents
    Journal of the Persian Gulf (Marine Science)/Vol. 2/No. 3/March 2011/8/9-16 Three-Dimensional Simulation of Qeshm Channel Currents Mahmoudov, Masoud1*; Chegini, Vahid1; Montazeri Namin, Masoud2 1- Iranian National Institute for Oceanography, Tehran, IR Iran 2- Tehran University, Tehran, IR Iran Received: April 2010 Accepted: December 2010 © 2011 Journal of the Persian Gulf. All rights reserved. Abstract Qeshm Channel is a shallow and narrow waterway located between Qeshm Island and the mainland in the vicinity of Hormuzgan Province, Islamic Republic of Iran. This channel is important because of its economic, industrial, fisheries and navigation role it plays as well as environmental issues it presents in the region. A prognostic study was performed to simulate currents in this channel, using COHERENS model. This model is a three-dimensional hydrodynamic model. Simulation of currents was carried out in 20 sigma levels from the seabed to the water surface during one month. It was assumed that the variations of seawater temperature and salinity, four main tidal constituents and the regional wind were the most effective factors in the numerical simulation. Finally, sensitivity analysis was carried out for each factor and the outputs of simulation were verified using the field data recorded by the experts from Iranian National Center for Oceanography. Very good agreements were found between the numerical results and the field data.

Biotic Cover and Surface Geology as the two components of the classification were used. Considering the extent and geomorphology of the area, 9 sites were designated using GPS. Density and distribution of biotic community were determined using 0.5×0.5 m quadrate and sediment was sampled up to 15 cm below the surface.

The data of a seismological network consisting of 17 stations, installed after the earthquake. We applied the single-station method (extended coda normalization method) to -1 -1 analyze Qp and Qs using the ratio of the P and S-wave to Coda-wave amplitude spectra, in the frequency range of 1.5 – 36 Hz, as a function of distance. The Qp and Qs is analyzed by using 66 lapse times of 22.5 – 87.5 seconds for -1 center frequencies 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 14, 16, 18, 20, 24, 28, 32 and 36 Hz. The values of Qp and -1 Qs estimated shows frequency dependence and decrease with increase of lapse time and distance indicates that the Q value increases with depth.

  • Chapter 5 Vision of Qeshm Island Development for 2036
    The Project for Community-based Sustainable Development Master Plan of Qeshm Island toward “Eco-island” Final Report CHAPTER 5 VISION OF QESHM ISLAND DEVELOPMENT FOR 2036 5.1 Vision and Objectives A vision should be established for sustainable development of Qeshm Island and shared by all the stakeholders including local residents, immigrants, tourists, and investors. Sharing a vision helps muster efforts of many stakeholders in undertaking new socio-economic activities to realize the sustainable development with the sense of common purpose. Based on this idea, the vision for Qeshm Island was prepared as described below. In December 2015, the JPT held the first consultation meeting with the local residents and QFZO as part of participatory process for preparing the ECO-QESHM Master Plan. The participants expressed their ideas on the needs and images of Qeshm Island, facilitated by QFZO and the JPT. The key words expressed in the meeting were analyzed and organized. The JPT attempted to find the most suitable development alternative for Qeshm Island through strategic environmental assessment (SEA), meanwhile it held a further consultation meeting. The JPT established four alternatives that reflected the ideas expressed in the stakeholder meetings by the representatives of local residents as well as the policy directions indicated by existing government documents. The Alternative D was selected as the most suitable alternative aimed at defining new paradigms. The selected development alternative pursues balanced, resilient and sustainable growth through community participation and careful use of local resources. The concept of resilient growth is aimed at redundant society against the socio-economic changes due to the external factors such as global economy, foreign relation and climate change, as well as the internal factors of societal shift.
