| Urban spatial morphology is the outward form of urban inner development, band affects people’s production and life and regional social, economic and cultural development in the process of its evolution, and also records the urban development history and value pursuit. Small town spatial development also has the render phase characteristics and regional disparities. Because of their underdeveloped development level, agricultural areas of function orientation and diverse topography, the contradiction between population growth and grain production, in the history of the four land and population migration channels and other special background, there are certain particularityin the urban development and evolution of space form in the spatial morphology development, which also showed the characteristics of space and time itself. The research on the space form of the small towns in Sourth Henan Province is helpful to find urban space and function space to urban development problems and the future development direction, and improve efficiency of urban space development, the small towns in a relatively backward level center.the space health development and the social and economic progress is of great significance.Research shows that: the center.the small towns with construction on the space development mostly high density, high functional combination, and elements of integration, compact layout, as well as the spatial development of the basic characteristics such as high sealing. The public space in the urban space, commercial space, traffic space, living space and industry space each main components such as evolution reflects the diversity and epoch features. Now, the internal space of small towns development exist mostly heavy light "quantity" and "quality" of space expansion disorder, light heavy "appearance" and "internal" space expression exaggeration, light weight "copy" and "characteristic" the space form of monotony, heavy light "instruction" and "demand" space function imbalance and other issues. And from the point of external space form, since 1949, the small towns of South Henan Province has experienced a little bit of shape formation stage, banded extension stage, the reticular development stage and filling stage of internal space form evolution process.The major factors of space that affect the spatial morphology of the small towns in South Henan Province are evolution of population development, social demand and psychological inertia, location conditions, infrastructure, industrial structure, as well as the policies and regulations, scientific and technological progress and town planning guide, etc. Through.the correspondence study type and its spatial form of small towns development of South Henan, comprehensive cluster more small towns region can be divided into planar space form, industry and trade type single heart radiation of small towns dotted space form, multiple small towns gathered mesh space form, tourism dual-core linkage strip spatial form of small towns and agriculture single heart small towns along the axis finger space form and so on several big feature type. Through in-depth research can also be found in the classification of spatial development of small towns, settlement from homogeneous isomorphism to heterogeneous heterogeneous space, developing space choice from township primarily toward diversified development, the regional space contact from isolated development to cooperate, space elements change from simple single to diversity. In general, urban function space evolution reflects obvious regional and modern change law of development. According to the research foundation, this article also put forward via classification guide to realize spatial differentiation development, improve production efficiency by concentrated intensive development space, and through the relationship between urban ecological optimization to ensure the safety of urban space development space form of development strategy. |
