Research On The Spatial Form Of Heilongjiang Rural Settlement Landscape

The countryside is the product of agricultural civilization;the important space we live in.And it is also the true portrayal of the beautiful countryside.Against the background of comprehensively promoting rural revitalization,the cognition of the spatial form of rural settlement landscape is insufficient,and the technical means of quantitative research are lacking.At present,in the process of traditional rural construction,it is difficult to obtain data resources,lack of reasonable planning guidance and objective cognition of the spatial form of regional and rural settlement landscape.Under the new situation,it is urgent to expand the quantitative means and methods of research and carry out scientific and rational thinking discussion on the spatial form of rural settlement landscape.Aiming at the problems of insufficient cognition of the spatial form of rural settlement landscape in Heilongjiang Province and the lack of quantitative research techniques and methods,this paper takes Heilongjiang Province as the research scope,takes representative typical villages as the research objects,and carries out the research mainly in the context of the spatial form of rural settlement landscape.Technology utilization includes unmanned aerial vehicle(uav)multiple view images 3d reconstruction technology.The study applies space syntax theory and technology,geographic information system spatial analysis technology,and shape index method.It also uses Rhino,Auto CAD,the Depth Map,?ustrator and Photoshop software to conduct the quantitative analysis of the rural settlement landscape space.The thesis analyzes Heilongjiang rural settlement landscape space form influence factors and typical villages distribution form.In this study,the spatial morphological characteristics of rural settlements in Heilongjiang Province were comprehensively recognized by combining the boundary spatial form,street spatial form and courtyard spatial form of rural settlements in the background.And the landscape design scheme was optimized and guided by the empirical study of typical counties.This study found that the value recognition of rural settlement landscape form in Heilongjiang is insufficient,and the proportion of regional typical representative villages at the national level is particularly low.In addition all kinds of typical settlement landscape forms need to be explored.Through technical analysis,it is found that the landscape spatial distribution of regional rural settlements is greatly affected by natural and human environment factors,especially the elevation of natural environment accounts for the largest proportion,while the slope aspect has little influence.Most villages in Heilongjiang Province are concentrated in the plain area.Especially Qiqihar,Mudanjiang and Harbin in the central and southern regions are the most concentrated.The distribution characteristics are also related to the historical floating culture.Based on the results of quantitive analysis,the boundary spatial form,street spatial form and courtyard spatial form elements of rural settlement landscape can comprehensively express the spatial form of rural settlement landscape in Heilongjiang Province from different perspectives.The most common boundary form of rural settlements is finger-like,followed by lump-like.The boundary form is most affected by natural environment,while terrain and water are both important influencing factors.Through the comprehensive analysis of integration degree,average depth and comprehensibility degree,the core area of the village which is integrated with the village space,and determined through the cold and warm levels of the axis is confirmed.What's more,it forms the weight hierarchy of accessibility and comprehensibility as the basis of guiding practice,so that space can be rationally sublimated from perceptual cognition.The spatial pattern of courtyards is mainly arranged in parallel.The spatial pattern of courtyards is the typical representative of the front yard and the front and rear courtyards.And the "small family big courtyard" is the most typical representative of the region.At last,22 green demonstration villages in Linkou County were studied,and the new thinking of design was used to guide the scheme design.Through the method of quantitative analysis and technical exploration,this study sets up the framework of cognitive rural settlement landscape space form and explores the research train of thought.It makes the Heilongjiang province rural settlement landscape space form of cognition more objective and provides rational scientific thinking method in the cold north rural construction.It also enriches the rural landscape research resources in Heilongjiang province,meanwhile it has an important theoretical and practical significance in the future study.
