Research On Rural Settlement Morphological Gene In Heilongjiang Province

Rural settlement space contains regional natural,economic,historical and cultural characteristics,and is the material carrier of rural life,rural production and valuable local landscape resources.In the long-term evolution process,the rural settlement space has formed a relatively unique and stable nature-human-space morphological gene,which contains the rules and laws of rural space construction,and the wisdom of taking advantage of nature and avoiding the harm of nature condensed in agricultural production and rural life.Rules,laws and wisdom can be fully used for reference,improved and evolved in rural settlement space derivation,village merging and new village construction,so that the morphological genes of rural and local characteristics can be inherited and continued.The proposal and implementation of rural development strategies such as Beautiful Rural Construction and Rural Revitalization Strategy accelerate the progress of rural construction,development and renewal.At the same time,blindly and excessively catch up with the level of urban development,the rural construction is introduced into the misunderstanding,the rural space features of the local,authenticity and unique characteristics gradually lost,“one look of urban and rural”and “one side of thousands of villages” are increasingly prominent.With the imbalance of "nature-human-space" coordination relationship,the organic relationship among rural space,natural environment,rural life and rural residents began to weaken,and the rules of long-term symbiosis collapsed at the same time of subversive changing in rural space.The development of Heilongjiang Province is slow in the protection of rural space style and the improvement of the quality of human settlements.The main keynote of rural development in Heilongjiang Province is to attach importance to development and neglect inheritance.In the face of the problems of blind development and construction,destruction of rural characteristic space feature and loss of local characteristic landscape,it is an important lawsuit to take objective and in-depth cognitive methods of rural morphology and spatial feature,to obtain accurate and comprehensive rural spatial feature information,and to formulate reasonable and feasible rural spatial feature response measures,which are important lawsuits for the protection,optimization and renewal of rural settlement space features in Heilongjiang Province.This dissertation takes the rural settlement morphological gene as the starting point to recognize the rural spatial feature and rural morphology,takes the rural morphological gene item identification and extraction,takes the morphological gene related information mining as the method,takes the morphological gene information atlas and the morphological gene information platform as the concrete application technical means.For the rural space landscape planning,the protection and the renewal,as well as the rural human settlements environment superiority,a new perspectives,ideas and methods system should be explored.The core research contents of this dissertation include:(1)According to the elements and levels of rural settlement system and rural spatial morphology system,combined with morphological gene theory,the rural settlement morphological gene system is decomposed into morphological gene items,morphological gene segments,morphological gene sequence and morphological gene map.The information framework of rural settlement morphological gene identification,extraction and mining is established.(2)According to the principles of natural environment difference,cultural custom diversity,industrial landscape typicality and spatial coverage balance,270 rural settlement research samples were selected in Heilongjiang Province,and the data platform of rural settlement morphological gene research of Heilongjiang Province was constructed by using geographic information system(GIS),which laid the data resource foundation for the identification and extraction of morphological gene items.Based on the comprehensive analysis of spatial morphology and spatial features data which obtained from a large number of rural field investigation and collection in Heilongjiang Province,this dissertation summarizes the spatial morphological characteristics and the determinants of morphological differences of rural settlements in Heilongjiang Province.(3)Using qualitative data mining and analysis methods,the massive rural settlement morphological data(remote sensing images,video and image files,survey data and panel data,rural interview records,etc.)were comprehensively analyzed and processed.The morphological factors and morphological representation nodes are formed by multiple coding and classification,and the basic morphological gene unit that can express the rural settlement space is identified according to the relationship between the two clusters of nodes.(4)Combined with the methods of spatial morphological quantification,clustering statistics,complex network analysis and spatial analysis,morphological gene segment information,morphological gene sequence information and morphological gene map information were mined from the basic data of morphogenetic quantification.(5)The quantitative information and qualitative data of rural settlement morphological gene were collected,and the matrix framework of rural settlement morphological gene information was established to form the information atlas of rural settlement morphological gene in Heilongjiang Province.(6)Combined with database,data analysis and data visualization technology,the morphological gene information atlas of rural settlement morphology is constructed as a specific application tool of information platform,and the functions of archiving,correlation and efficient transfer of rural settlement spatial morphology and space landscape information are realized.The results of this research,on the theoretical and methodological level,carries out in-depth study on the morphological gene in rural settlements,including improving the identification and extraction methods of morphological genes,the information mining path of morphological genes,and the construction method of morphological gene information atlas.On the application and practice level,the research results provides accurate information reference and technical tools for the planning,protection and renewal of rural settlement space landscape,and provides reference basis and practical ideas for rural spatial planning,design and construction in Heilongjiang Province and even in the whole country.
