盱眙县龙虾养殖气候适宜性区划

利用盱眙县酸雨资料、气象资料、土壤类型资料以及DEM数据,选取夏季高温日数、酸雨、土壤类型,海拔高度等作为影响龙虾生长的关键因子,采用层次分析法建立了综合气候适宜性区划指标模型,借助ArcGis 10.0技术平台得到盱眙地区龙虾养殖发展的气候适宜性区划图。研究结果表明盱眙县龙虾养殖适宜区主要分布在盱眙县北部,较适宜区主要位于县内东南部丘岗地带,不适宜区位于盱眙县西南部的低山丘陵地带。本研究结果可为盱眙县龙虾养殖规划布局提供一定的参考依据。

The Climatic Suitability Zoning of Lobster Cultivation in Xuyi County

Using the acid rain data, meteorological data, soil type data and DEM data of Xuyi County, we selected summer high temperature days, acid rain, soil type, altitude as key factors influencing lobster growth and built the agro-climatic zoning model with analytic hierarchy process method. We adopted ArcGIS 10.0 to divide the climatic suitability zoning of lobster cultivation in Xuyi. The results show that the suitable areas mainly distribute in north Xuyi, and the relatively suitable areas mainly locate in hilly areas in the southeast, and the unsuitable areas locate in the low hilly area in the southwest. The study could provide references for planning layout of lobster farming in Xuyi County.
