Evolution of Agricultural and Cultural Heritage Landscape in Sangji Fish Pond:A Case Study based on Linghu Town,Huzhou
摘要
Abstract
The aim of the current study was to understand the historical changes and evolution of the agricultural heritage of Sangji Fish Pond in Linghu Town,Huzhou City,China,which is located on the south shore of Taihu Lake.Additionally,the study aimed to explore the current problems associated with the Pond's agricultural legacy.Towards understanding the evolution of the agricultural heritage of Sangji Fish Pond,a literature review focusing on the qualitative and quantitative perspectives associated with envi water body extraction,the water body change intensity index,and the graphical analysis,comparative analysis,and field survey methods was conducted.First,it was found that the mulberry-based fish pond system in Linghu Township has undergone four phases,namely germination and birth,pioneering and development,progress and prosperity,and adjustment and development.It is now in the fourth phase of protection and development.Further,the pond system has gradually shifted from a single production function to carrying a variety of social functions,with associated opportunities and challenges.Second,the decline in economic benefits associated with the sericulture industry has led to a local emphasis on fishing rather than planting,where the scale at which mulberry is planted has reduced and the scale of fish farming has increased.Further,the landscape around the pond system has been reduced by the number of fish farmers.The Keetang system of landscape area expansion and erosion of the base,particularly in the 1992～2002 interval,increased by 12%,where the Keetang ratio from the traditional farming period of 6:4 into today's 4:6(or even 2:8)has led to the gradual disappearance of the adaptive characteristics of the agricultural landscapes.Third,scientific and technological advances have increased the popularity of mechanized farming,shifting the morphology of Keetang texture,from traditional sparseness—towards density and regularity.From the Song,Yuan,Ming and Qing dynasties of the mulberry base erosion of paddy fields,to today's fishpond expansion and encroachment on the mulberry base,the expansion of the clusters onto the surface of the mulberry base fishponds has gradually spread.The texture of the mulberry base fishponds comprises a neat and regular square grid and,thus,the traditional"curve of small fishponds,the large base of the surface of the landscape texture"is rarely preserved.The combination of the elements of form can be divided into points and lines.With the development of towns and cities,the pattern of settlements has evolved from point-like dispersion and line-like expansion to face-like aggregation.Pieces of residential,commercial and industrial construction land have expanded into agricultural land,and the spatial and textural distribution of the land has then altered over time.Additionally,the traditional ecological cycle model has been damaged,leading to an imbalance of the material and energy in the system that cannot rectify itself.Addressing the problem requires an external,artificial energy supply,which results in the accumulation of pond mud and damage to the sustainability of the system.Finally,the traditional"curved small fishponds and large basal landscape texture"have been preserved,yet the stability and sustainability of the system has been damaged.The operation mode of the pond system has developed multiple modes such as oil(vegetable)-based fish ponds,"runway fish",pond-based chicken farming,and fishery-photovoltaic complementation.However,this has not yet stimulated the vitality of the mulberry ponds in a comprehensive way.The traditional mode of the Sangji fishpond has been substantially damaged,with ecological erosion,declining economic value,expansion of the water landscape encroaching on the base surface,and compression of agricultural space by the division of land for construction(among others).Further,the cyclic ecological mode has gradually disappeared.Therefore,the sustainable development of Sangji fishponds and the innovative agricultural heritage mode,the protection strategy of the triple integration of the construction of towns,the income from production,and ecological protection require substantial improvement and advancement.关键词
