The development of marine fishery geographic information system can be divided into three phases: mapping, electronic atlas and information system. It has been used in evaluation of fish habitats, relating fish distributions to environment, site selection for mariculture and building the position related fishery database, etc. And it can also be applied to the fishery modeling, artificial enhancement, fishing quotas management, etc.展开更多
目的:利用地理信息系统(Geographic information system,GIS)分析预防接种门诊服务可及性,为合理规划预防接种服务模式提供依据。方法:运用平均最邻近方法分析区域内门诊空间分布模式,利用热点分析方法分析以疫苗接种量为权重区域内接...目的:利用地理信息系统(Geographic information system,GIS)分析预防接种门诊服务可及性,为合理规划预防接种服务模式提供依据。方法:运用平均最邻近方法分析区域内门诊空间分布模式,利用热点分析方法分析以疫苗接种量为权重区域内接种人员、接种周期冷链设备和门诊面积的配置和设置情况,缓冲区分析方法分析预防接种门诊服务范围。结果:此研究区域内预防接种门诊空间分布格局呈离散性,门诊接种人员、接种服务时间、冷链设备、门诊服务面积在空间上配置具有差异,并鉴别出资源配置充足的热点区域58个和资源配置薄弱的冷点区域15个,预防接种门诊服务的可及范围为28 666km2。结论:利用距离分析、空间热点分析、缓冲区分析方法分析预防接种门诊服务的空间分布格局、服务资源的配置情况、服务可及范围,可为区域内预防接种门诊服务模式和资源配置提供依据。展开更多
