Study On The Adaptive Landscape Pattern And Formation Mechanism Of Traditional Villages In Zijiang River Basin

In the process of managing water resources and combating flood disasters,ancient civilizations have continuously adapted to the village water environment system,improved water use efficiency,eliminated the threat of water disasters,accumulated many survival experiences with ecological value,and formed a water adaptive landscape pattern with basin characteristics.However,the protection and utilization of water adaptive landscape patterns in villages in China face multiple challenges.On the one hand,blind development that disregards traditional concepts greatly damages the water adaptive landscape pattern.On the other hand,with the growth of population and changes in lifestyle,the adaptive landscape pattern and water elements of traditional villages can no longer fully meet the diverse needs of modern people in water drainage,water quality purification,rainwater and flood regulation and storage.Therefore,the paper selects traditional villages in the Zijiang River Basin as the research object,explores the ecological wisdom of traditional villages living by water,analyzes the spatial distribution,morphology,mechanism,and sequence characteristics of water adaptability in traditional villages,constructs a complex water adaptability system analysis framework,explores the formation mechanism of traditional village water adaptability landscape pattern,and proposes optimization strategies for the protection of traditional village water adaptability landscape pattern on this basis.It is very necessary.The main work content and research conclusions of this article are as follows:(1)The spatial distribution of traditional villages in the Zijiang River Basin.The nuclear density analysis shows that the distribution of traditional villages shows a clear "spatial agglomeration",with two dense belts and three nuclear dense areas along the direction of the Zijiang River,with traditional villages in Anhua County being the most densely distributed.The results of buffer zone analysis and landform reclassification show that the distribution of traditional villages exhibits clear characteristics of "hydrophilicity" and "shallow mountain".With the increase of distance,the number of traditional villages gradually decreases,and the proportion of waterfront villages is as high as 53.8%.And there are 12 traditional villages located near the main stream of the Zijiang River.Under the joint influence of mountains and rivers,villages are divided into five distribution types:high mountain waterfront type,hill waterfront type,hill waterfront type,plain waterfront type,and plain waterfront type,with the hill waterfront type being the most representative.(2)The spatial pattern of adaptability of traditional villages to falling water in the Zijiang River Basin.The paper analyzes the spatial pattern of water adaptability of traditional villages in the Zijiang River Basin at three different scales:water adaptability spatial form,water adaptability spatial mechanism,and water adaptability spatial sequence.At the macro spatial level,the location and morphology of villages under the influence of water systems and landforms can be divided into four types:surround type,through type,side by side type,and accumulation type.At the mesoscale spatial mechanism level,under the influence of production and daily life,villages exhibit four types of village street mechanisms:cluster aggregation,curved belt extension,branching diffusion,and scattered settlement,as well as three types of farmland mechanisms:patch shaped Sakata,square shaped pond field,and crescent shaped terrace.At the micro spatial sequence level,combined with the arrangement and combination of landscape elements and water management methods within the village,the village is further divided into a "river road village field" type sequence with "drainage" as the main feature,and a "river road village field" type sequence with "storage" as the main feature.(3)The formation mechanism of the adaptive landscape pattern of traditional villages in the Zijiang River Basin based on CAS theory.Firstly,from the perspective of water adaptability,the paper constructs a research framework for the traditional village water adaptability landscape pattern,which is composed of an executing entity system,a material space subsystem,a water ecological space subsystem,and a social and cultural subsystem.Focusing on the theoretical framework,this study specifically studied the main execution system,three major support systems,operation mechanism,formation path,and formation stage of the formation mechanism of the adaptive landscape pattern in traditional villages.The traditional village water adaptive landscape perceives external stimuli during the evolution process,and is influenced by bifurcation,mutation,and emergence,resulting in an increasingly complex water adaptive landscape pattern.(4)Optimization of Traditional Village Waterfall Adaptability Landscape Pattern from the Perspective of CAS Theory.Firstly,propose a diversified optimization goal of "orderly contraction,pattern recovery,and pattern growth".Under the principle of optimizing the water adaptive landscape pattern,the optimization strategy of "activating the landscape function to improve adaptability,building a network system to maintain village anti-interference ability,and promoting village transformation ability through multiple collaborations" is proposed from two aspects of "operation mechanism regulation" and "execution subject participation",in order to achieve the goal of diversified traditional village water adaptive landscape pattern optimization and improve the environment in the new era,The adaptability of traditional villages to the landscape pattern of falling water.
