Study On The Construction Of Spatial Morphology Gene Map Of Hanzhong Towns In Southern Shaanxi

Small and medium-sized cities and towns in southern Shaanxi have long been under the influence of a special natural geographical environment,giving birth to a unique spatial pattern of small cities and towns,which is rich in The spatial culture of the town However,in recent years,the use of undifferentiated strategies to promote the development of small towns has led to problems such as the uniformity of thousands of towns and serious problems of assimilation.How to reveal the unique and excellent spatial characteristics of small and medium-sized towns in southern Shaanxi?How to establish a research system on the spatial patterns of small and medium-sized cities and towns in southern Shaanxi?How to systematically and effectively extract and express the spatial features of small and medium-sized towns in southern Shaanxi?The answers to the above questions are urgentThis paper draws on the theories of "urban spatial pattern genes" and "settlement landscape genes" to propose the spatial pattern genes of small and medium-sized towns in southern Shaanxi.Concepts,construct the theoretical framework of spatial morphology gene mapping of small and medium-sized cities and towns in southern Shaanxi,establish the corresponding technical system and carry out the typical objects.Example Operations The article systematically and effectively answers the above three questions.First of all,the article takes the research framework of "frame,group and boundary" as a starting point,and takes into account the characteristics of the research object to form the small town space.The principles and methods of morphological gene identification and extraction,and then integrate the theory of "gene mapping" to clarify the spatial morphology of small towns.Gene mapping connotations to construct a gene mapping framework.Secondly,using quantitative methods with the help of software platforms such as AutoCAD,ArcGIS,Fragstats,and so on.The spatial morphology genes were extracted for typical small towns and cities in Shaanxi,and each gene was evaluated using quantitative indicators to It is convenient to describe the gene classification.On the basis of classification,the whole gene map information map and typical pattern map of small and medium-sized cities and towns in southern Shaanxi are summarized and plottedThe conclusions of the study are as follows:① the similar genes in the spatial pattern of small and medium-sized cities and towns in southern Shaanxi show obvious differences,and their quantified data are distributed in high,medium and low ranges;②there are obvious typologies of the same genes,and when the quantified values of genes are within a certain range,they will show the same gene map type;③ there are 9 types of genes and 36 gene map features in the spatial pattern of small and medium-sized cities and towns in southern Shaanxi,and the whole gene information map of the spatial pattern of small cities and towns under different geographical environments shows a lack of information,and overall this difference is not greatThese results prove that by mapping the spatial morphology genetic map of small and medium-sized towns and cities in Shaanxi can accurately and intuitively reflect the Shaanxi The characteristics of spatial patterns of small and medium-sized towns.The establishment of the gene map of the morphology of small towns will help us to find the essential rules and characteristics of spatial morphology,and will also help us to find the spatial characteristics of small towns in southern Shaanxi.Small and medium-sized towns provide a scientific reference for maintaining their character in future planning and design.
