Climate Suitability Zoning for Shrimp Farming in Jimo City
中文摘要：
基于山东省即墨市1961—2012年气温、降水、日照、风速等气象资料及地形、土壤、河流等数据，采用标准化方法、层次分析法、加权综合评价法，选取对虾养殖评估指标，结合GIS空间分析技术，对山东省即墨市对虾养殖的适宜性进行区划。结果表明：即墨市对虾陆地养殖最适宜区主要分布在王村中心社区南部、温泉街道大部、鳌山卫街道北部、田横岛省级旅游度假区中部及金口中心社区局部，面积大约占养殖区总面积的34.20%；适宜区较大，主要分布在金口中心社区、丰城中心社区、鳌山卫街道等，占总面积的48.23%；一般适宜区较小，金口中心社区及丰城中心社区北部、鳌山卫街道东南部有小面积分布，仅占17.57%。总体表现为距海近、地势低平及气候适宜性较好的地区对虾养殖适宜性高。
