摘要:
[目的]探究江苏省水产养殖池塘县域集中度空间分异特征及池塘养殖业地理分布格局,为该省优化池塘养殖业空间布局提供参考。[方法]基于遥感影像提取江苏省水产养殖池塘空间位置及面积等数据。以景观生态学为理论依据,运用主成分分析法构建基于6个景观格局指数的江苏省水产养殖池塘县域集中度空间分异综合评价体系。并基于渔业统计年鉴数据,选取养殖面积、产量等池塘养殖业典型指标,运用空间自相关法对该省池塘养殖业进行研究。[结果](1)江苏省水产养殖池塘县域集中度空间分布综合水平地区差异显著,分布不均匀。空间上分布相对集中的3个县域(市辖区)为金湖县、苏州市辖区及连云港市辖区,相对分散的3个县域(市辖区)为如皋市、灌南县与丰县; (2)江苏省池塘养殖业具有显著的、正向的空间自相关性,其空间分布呈现出非随机的地理集聚格局。中部的洪泽湖、高邮湖流域及南部的太湖流域为该省池塘养殖业的主要产区。[结论]基于景观格局指数与空间自相关的研究方法将数量统计与空间分析进行有效的结合,能够较好地揭示江苏省水产养殖池塘县域集中度空间分异特征及池塘养殖业的基本特征与地理分布格局,为该省优化池塘养殖业布局,促进产业转型升级提供参考依据。

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.
Key words:  aquaculture pond  pond culture industry  geographical distribution pattern  landscape pattern index  principal component analysis  spatial autocorrelation
