Comprehensive Evaluation Of Village Construction And Development Space

Land space is the basic carrier of the economic and social development of the village.Optimizing the construction and development pattern of the village land space is the basis for the development of village planning and is of great significance to the overall coordination of rural revitalization.A village is a gathering point for villagers to engage in production and life,and is the main form of gathering the vast rural population in my country.As the most basic unit of rural structure and development,as the opportunities and challenges of rural development coexist today,under the background of ecological environment protection,how to rationally use and allocate resources,and more scientifically and sustainably promote rural social and economic development,has become a global Issues of common concern to society.As an important guarantee for rural social and economic development,the optimization of village space has become a hot topic in academic research.In recent years,although a lot of achievements have been made in the research on the optimization of village space in the academic circles,there are still some areas for improvement.For example,how to determine the evaluation unit of village spatial optimization research more reasonably,how to get closer to the reality of village development,and how to establish a more scientific evaluation system.To this end,this research uses a multi-objective optimization method on the basis of existing research to determine the evaluation unit for the optimization of village land layout while taking into account the evaluation accuracy and work efficiency.Three aspects: the degree of satisfaction of space for villagers ' production and life and the impact of village development on the ecological environment are to construct an evaluation system for the optimization of village land layout,comprehensively consider the interaction of the three factors,and evaluate specific plots.In the context of controlling the total scale of construction land,the spatial scanning statistical method is used to determine the construction space layout within the village area according to the evaluation results,and theexpansion area of construction land and the flexible area of construction land are delineated.The three factors of construction suitability,construction cost,and ecological sensitivity have an important impact on the organic unity of economic,social and ecological goals in the development process of the village.Based on this,a comprehensive evaluation system is established,and a variety of analysis methods are used to evaluate the evaluation unit Perform correlation analysis,spatial overlay analysis,and spatial cluster analysis.Considering grid division efficiency and division accuracy,without assigning any weight,the potential optimal solution(set)is finally obtained.The division scales are:20m?20m ?50m?50m ? 60m?60m and 100m?100m ?Taking Chenjiafang Zhenjiang Village in Xinshao County as an example,based on the comprehensive quantitative evaluation results of the village construction and development space and the analysis and comparison of the evaluation scale results,the scale of the evaluation unit of the study is determined to be 50m?50m.Combining the prediction results of the construction land scale demand of the village at different time stages,the spatial scanning statistical method is used to analyze and determine the village construction new area and elastic area in the village construction development plan.
