Evolution And Driving Forces Of Rural Landscape Pattern Along Laodao River

In the past 40 years,with the rapid flow of urban and rural factors,the traditional rural areas in China have been greatly impacted by urban development factors,and the rural problems have become more and more serious.In order to solve the three rural issues and narrow the gap between urban and rural areas,China has implemented a series of agricultural related strategic measures.The steady progress of national policies can effectively alleviate the rural problems and improve the rural economic level.However,the construction and development of rural areas also aggravate the problems of rural land empty waste,environmental pollution and characteristic extinction.The continuous interference of human activities seriously affects the evolution process of the landscape pattern,but the existing research rarely involves the in-depth analysis of the driving mechanism of the evolution of rural landscape pattern.In order to coordinate various contradictions in the process of rural development,this study,from the perspective of landscape pattern evolution,takes the typical rural areas in central and southern China--the rural area along The Laodao River as the object,explores the evolution process and driving mechanism of landscape pattern during the period of rural vigorous development under the guidance of national agricultural policy in recent 20 years,and establishes the landscape dynamic change model and driving force analysis model to explore the main driving factors of rural landscape pattern evolution,and analyze the difference of the influence degree of each driving factor on the landscape pattern.It is hoped that under the background of urban-rural integration development,it can provide reference for promoting the implementation of Rural Revitalization Strategy and the sustainable development of new rural in the future.The main contents of this study are as follows:① The analysis framework is put forward.Combined with the existing theoretical basis and the meso scale and research purpose of this study,the rural secondary landscape classification system is established,and the landscape dynamic change model and driving force analysis model are constructed.Combined with the landscape index method,the analysis framework of this paper and the technical route of the research on the evolution of rural landscape pattern and driving force along Laodao River are put forward;② Dynamic analysis of rural landscape pattern along Laodao river.The evolution process of rural landscape pattern along Laodao River in 2003,2011 and 2019 was analyzed from the aspects of landscape centroid migration,single landscape dynamic change degree,landscape transfer matrix,comprehensive dynamic degree,patch type level index change and landscape level index change.According to the change process of landscape pattern,the changes of rural landscape pattern and landscape index of Laodao River in 2011,2013,2015,2017 and 2019 were analyzed;③The driving factors of rural landscape pattern evolution along Laodao River were analyzed.Under the driving force analysis model,through Pearson correlation analysis and grey correlation theory,this paper analyzes the relationship between the rural landscape pattern evolution of Laodao River and the driving factors from 2011 to 2019,finds out the main driving factors affecting the landscape pattern change,and comprehensively discusses the national policy,climate,socio-economic,land type driving mechanism of the rural landscape pattern evolution of Laodao River;④ The evolution of rural landscape pattern along Laodao River and the construction of beautiful countryside.Based on the evolution of landscape pattern and the main driving factors,combined with the process of rural development and the construction of beautiful countryside in the research period,the causes of fragmentation and the existing rural problems are considered and analyzed as a whole,and suggestions and enlightenment are given.The main conclusions are as follows:① A set of meso scale research framework for rural landscape pattern and driving forces is proposed;②The main driving factors affecting the evolution of rural landscape pattern along Laodao River are average temperature,total number of households,total population,reservoir pond,rural residential area and farmland landscape patch area.Rural social development,rural agricultural industry development,rural industrial innovation and typical "rural diseases" are the main driving factors affecting the evolution of rural landscape pattern in the study area;③Combined with the current situation and main problems of rural development along the Laodao River,the general requirements of Rural Revitalization Strategy are taken as the banner,and the relevant suggestions and Enlightenment from the perspective of landscape pattern are given.
