There is a strong paradigm shift in the literature recently, on how rural development and urban development affect one another. The conventional wisdom of the last three decades suggests that urban and rural developments are separate and compete with each other for resources. However, a closer looks reveals that this is far from the truth. Relationship and range between urban-rural have many variety efects on shape, growth and rual settlement development. It effect on its inside and outside relationship. With attention to these relationship in process of evolution and developing of urban-rural points, in addition to study of varieties and causes of relationship, recognition effects and results of economics, society-cultural and spatial-skeletal on urban-rual linkage is essential. Therefore it is important that decrease negative effects. It helps to bookeeping of theses relationship between rural-urban and it helps to developing of sustainablity in rural-urban linkage. In this paper, first, we discuss about urban-rural linkage and its effects factors on Iran and seconds we study some models about urban-rural linkage and theirs effects on its. This investigation deals to operation of urban-rural linkage and spatial links in Homeh District of Harsin county(in central section). In this investigation we use from SPSS software for analysis(for example correlation, regression). This paper shows that how urban-rural linkage effect on social, economic and skeletal change. Investigative method was documentary and field with questionnaire. These paper say that urban-rural linkage do not effect on urban-rural linkage and more effects on social, economic and skeletal change and case study of this paper do not have profit from skeletal and organic effects of urban-rural linkage. This paper shows that tradition pattern of housing change and convert to new archtecture that is like urban architecture. Land ownership decrease. This paper show that in this place, agriculture productiion decrease. This investigation says that land use is of varieted. In this Harsin, cost of comodity and house increase and there make change of cultural people. This paper say that in this harsin, lands piece meal. Results of hypotesis test show that reral-urban linkage make many change in economic, cultural and skeletal pattern in Harsin. Cities have many effects in sphere of influence that include: villages send to cities many agricultures crops, immigration of people(not stability) to cities from villages. Cities send consumable comodity to villages and they sernt to villages work forces. Trade, migration and remittances, the exchanges of goods, people and money, are the most obvious signs of the relationship between urban and rural areas. Other influences are less tangible: standardized curricula and increased access to education the growing reach of the mass media commercial advertising and campaigns by service organizations the influence of cultural and religious networks, and the spread of urban services to the rural areas all increase the strength and depth of the interactions between them.
