Landscape Pattern Analysis And Optimization Research Of Hutou Village In Chongqing Based On The Integration Of Agriculture And Tourism

In recent years,with the rapid development of my country’s economy,urban and rural coordination efforts have been increasing.In the report of the 19 th National Congress of the Communist Party of China,the Party first proposed the strategy of rural revitalization and gave full play to the advantages of rural resources.On the other hand,the transformation of tourism concepts has enabled rural tourism to flourish,and the integration of rural tourism provides an important opportunity for rural transformation and construction.By referring to the relevant literatures on the integration model of farming and tourism,landscape pattern analysis,dynamic simulation and optimization,the mountain and rural ecological environment is relatively fragile.At the same time,the lack of scientific guidance for rural planning and construction can easily lead to environmental pollution.Clarify the practical needs and necessities of the integration of rural farming and tourism development in my country,and the importance of landscape pattern optimization and the development of farming and tourism integration.This article selects Hutou Village in Chongqing as the research object,conducts a spatial survey of the status quo,analyzes the landscape pattern using the landscape pattern index,information entropy and other indexes,and constructs a coupling model of BP neural network and cellular automaton(BPNN-CA for short)Based on the simulation and prediction,based on the ecological,production and living levels,an optimization strategy was proposed for the landscape pattern of Hutou Village to form an optimized layout and test.The research results are as follows:1.The natural ecological spatial foundation of Hutou Village is relatively complete,but during construction,the mountain is excavated,the road system divides the natural patches,the natural landscape of the garden is degraded,and the natural patches are obviously broken;the supporting facilities for agricultural production are backward and the land is intensified The degree is low,the high-quality land in the middle is deserted,and the added value is low;the rural living space structure is messy,the mix and match is obvious,the public service space is insufficient,the attraction is low,the traditional cultural integration degree is low,the landscape development and utilization awareness is weak,and the rural homogenization.2.Use satellite maps,elevation data and other data in 2015 and 2020,and divide them into 6 types: cultivated land,garden land,forest land,construction land,water area,and unused land.Using Fragstats software,select 10 landscape pattern indexes from the type level and Landscape level The calculation and analysis of the landscape pattern in the study area in 2015 and 2020 respectively.The area of cultivated land,forest land and unused land continued to decrease,and the growth of garden land,construction land and water area showed a trend.The cultivated land is obviously occupied,and the patches are showing a tendency to fragment.The scattered and fragmented layout of construction land and unused land has seriously affected the landscape pattern and brought ecological risks,and exposed the landscape pattern of Hutou Village lacking scientific and rational planning.3.According to the information entropy calculation of the land use structure,the information entropy of Hutou Village in 2020 is greater than that in 2015,reflecting the orderly decrease in the landscape pattern during the five-year construction of Hutou Village and the weakening of the buffer capacity of the land use system to external interference.4.Build a BPNN-CA coupling model,and improve the CA conversion rules through training,simulation,and data verification.Taking the land use landscape of Hutou Village in 2020 as the base year,the model was used to simulate the landscape pattern of Hutou Village in 2025.The analysis shows that without interfering with the landscape pattern of Hutou Village,construction land will continue to increase and unused land will decrease,scattered patches will increase,garden and forest land will be affected,and construction land will be occupied,accelerating ecological deterioration and fragmentation.Based on the multi-level research on the landscape pattern of Hutou Village,the integration of the development needs of farming and tourism,combined with the three levels of ecology,production,and life,to form an optimization strategy for the landscape pattern: clear the overall positioning of farming and tourism,improve the ecosystem service function;promote Land ecological classification;lively adjustment of goals to promote ecological sustainability;expansion of agricultural tourism industry functions and reconstruction of production space;protection of agricultural landscapes and creation of mountain agricultural tourism characteristics;construction of agricultural tourism composite space to improve space use efficiency;active creation of agricultural tourism Symbolize space and activate rural culture.Draw the landscape landscape optimization map for 2020,and through the comparative analysis of landscape landscape index and information entropy,it is verified that the optimization measures and optimization landscape have obvious effects on buffering ecological fragmentation,improving layout order,and strengthening landscape connectivity.In Hutou Village,the rural landscape will be promoted with an excellent landscape pattern,and the rural landscape pattern will be protected with a healthy farming and tourism integration model.
