| Regional landscape is the most intuitive manifestation of human surface activities within a certain area,and it is a comprehensive form of coupling development between the regional humanistic process and the natural environment.With the advancement of urbanization,the contradiction between man and land is becoming more acute.With the development of land and space planning,the interest in regional landscape is gradually increasing.The convening of the 19 th National Congress of the Communist Party of China put forward a new concept of high-quality development.In this context,the high-quality development of regional landscapes is gradually on the agenda.Therefore,it is necessary to clarify the intrinsic value orientation of regional landscapes and evaluate regions through spatial performance.The high-quality development status of the landscape provides a quantifiable reference basis for the sustainability and high-quality development of the regional landscape.The northern part of Anhui has obvious characteristics of regional landscape.It is an agricultural plain area in Anhui Province and even the whole country,and it is also the most important late-developing area.This article first conducts in-depth research on the regional landscape through a large amount of literature collation and data collection.Explore and summarize the profound connotation of the regional landscape.Finally,based on the evidence-based effect of landscape performance on the built environment,it is concluded that the spatial performance of regional landscape is the evidence-based effect on the aggregate system of regional economic production,social life and ecological environment.Secondly,the fuzzy matter-element analysis method is selected,15 evaluation indicators are selected from the three subsystems of economic production,social life and ecological environment,and the spatial performance evaluation system of the northern Anhui regional landscape is constructed,and the regional landscape of the northern Anhui region from 2014 to 2018 is calculated.The time change characteristics of economic production,social life and ecological environment and its comprehensive spatial performance index,and the use of Arc GIS software and Geo Da software to analyze the spatial and temporal changes and correlation characteristics of the spatial performance index,and at the same time based on the obstacle degree model and the geographic detector to the obstacle The factors were probed.Conclusion:(1)From 2014 to 2018,the regional landscape spatial performance index of all districts and counties in northern Anhui showed an overall upward trend,especially in terms of social life,the growth rate was significant,and only a few districts and counties in terms of economic production and ecological environment performed as Negative growth,the rest are positive growth,and the comprehensive spatial performance index shows a positive growth trend;(2)From the perspective of temporal and spatial differentiation,the regional landscape spatial performance index in northern Anhui shows certain temporal and spatial changes.And showing the characteristics of spatial correlation;(3)According to the calculation results of the obstacle degree model and the geographic detector model,each factor has different degrees of influence on each district and county unit.The relevant indicators of economic production and social life have obvious obstacle effect on the landscape spatial performance index of Northern Anhui,and the interaction strength of social life and its indicators with each subsystem and its indicators is significant.Finally,based on the results of the analysis,an analysis of the differences in the impact of the macro-environment,including the history,resources,physical geography,location,society,and policies of northern Anhui,as well as specific factors based on economic production,social life,and ecological environment,was carried out,and then put forward accordingly.The corresponding promotion strategy.At the same time,it is pointed out that taking northern Anhui as the research area is of great significance to the sustainable development of similar areas in northern Anhui and the whole country and the construction of high-quality landscape space.Figure[ 22 ] table[ 11 ] reference[ 95 ]... |
