II: has been more than two decades that the concept of sustainability has been gained a basic role in the global, regional, national and local development plans (urban design and planning). Therefore, many studies have tried to transform the concept of sustainability iii the form of “principles and rules” of urban design and planning. Nevertheless, the scientific and professional society of urban planners in Iran has not achieved a properly formulated set of principles and rules. The first condition to reach such a goal would be considering the evolution of cities according to new information technologies , which results in globalization. Thus, globalization is considered here as a background which is affecting the cities and changing them into global cities. Then, human needs in the global cities both as a member of world society and a local society (Iran) have been considered.
lnthe author’s view, development planning will not lead to sustainability unless defined principles and rules for improving both global and local needs of society are suggested. Therefore, the result of a comparative analysis between the two sets of information:
1. global suggestions extracted from International studies,
2. Empirical ways extracted from traditional cities of Iran.
is presented. This analysis has led to two important expected results:
1. Formulation of of human needs in an ideal type global city,
2- Formulation of some common principles and rules for sustainable urban design of Iranian global cities in the future, which is based on recognized human needs.
Because of the great amount of the formulated principles and rules, only some of them which convey the biological needs as one of the most important requirements, are presented.
Key words:

Abstract:
The importance of the ecology and ecotourism and natural conservation of the natural southern coastal areas of Caspian sea, especially the international coastal wetlands of Guilan, Mazindaran and Golestan provinces which serve as places of refuge for many migratory birds as well as habitat for aquatic animals, have been the reason for undertaking this study. The study area with average altitude -23 m and surface of 8000 ha covers coastal areas near the cities of Langerud and Lahijan. It begins from the Caspian Sea on the east and from the western side of the Amirkelayeh and other wetlands on the west. The northern and southern limits of the study area is defined by main bridge in the rural Chamkhaleh and the main bridge in the rural Jirbagh. Amirkelayeh wetland which has been designated as an international wetland is situated in this region.
This study covers climatic effects and geological conditions in the region. On the whole 320 plant species were examined of which 105 species were related to the Amirkelayeh wetland. Some of these determined species have been reported as new records for the flora of Iran and some of them are endemics in Hyrcanian area. Throphytes and hemicryptophytes are the most frequent life forms of the area. According to chorology, plants belong to several phytoregions. Additionally, plants found in three main aquatic, sandy and dry plain habitats were also studied. Limits and characteristics of each habitat are thoroughly explained.
