| Abstract: |
| This study explores the spatial differentiation characteristics of the aquaculture ponds and the geographical distribution pattern of pond culture industry in Jiangsu province, which provides reference for pond culture industry planning in Jiangsu province. Extracting data from aquaculture ponds in Jiangsu province based on remote sensing images. Based on the landscape ecology, a principal component analysis method was used to construct a comprehensive evaluation system for spatial differentiation of aquaculture ponds in Jiangsu province based on six landscape pattern indices. Based on the fishery statistical yearbook data, the typical indicators of pond culture in aquaculture area and yield were selected, and the pond culture industry was studied by the spatial autocorrelation method. The results showed that: (1)The regional differences in spatial differentiation of aquaculture ponds in Jiangsu province were significant and unevenly distributed. The three regions with relatively concentrated distribution in space were Jinhu county, Suzhou municipality and Lianyungang city. The three regions that were relatively scattered are Rugao city, Guannan county and Feng county. (2) The pond culture industry in Jiangsu province had remarkable, the positive spatial autocorrelation, its spatial distribution presented a non random geographical agglomeration pattern. The Hongze Lake in the central part, the Gaoyou Lake Basin and the Taihu Lake Basin in the south were the main producing areas of the pond culture industry in the province. The research method based on landscape pattern index and spatial autocorrelation can effectively combine the quantitative statistics and spatial analysis, which can better reveal the spatial differentiation characteristics of the aquaculture ponds in Jiangsu province and the basic characteristics and geographical distribution pattern of pond culture industry. This research can provide reference for the province to optimize the layout of pond culture industry and promote industrial transformation and upgrading. |
