  1. Using GIS and Spatial Analysis Approaches for Crop Suitability Mapping 利用GIS与空间分析法进行作物适应性作图 Authors: David B. Hannaway Professor of Crop Science 韩大卫 - 俄勒冈州立大学教授 Christopher Daly Professor of Geosciences 戴克利 - 俄勒冈州立大学教授 GIS and Spatial Analysis Approaches

  2. 利用GIS与空间分析法进行作物适应性作图 GIS-based species suitability mapping • 过去的方法 • 新方法-对气候和土壤进行建模和测绘并定量决定容限,据此进行匹配 • USDA-FAS-EMP项目提供具体气候测绘的经费 • USDA-FAS-RSED项目提供土壤测绘的经费 • PRISM小组为量化容限评估开发IMS应用程序 • 组合测绘 • 田间实验验证 • Historical approaches • New approach – modeling and mapping climate and soil and defining quantitative tolerances, then matching • USDA-FAS-EMP project provided funding for detailed climate mapping • USDA-FAS-RSED project provided funding for soil mapping • PRISM group developed IMS application for quantitative tolerances evaluation • Combination mapped • Field trials used for validation GIS and Spatial Analysis Approaches

  3. Before current computer tools were available for generating GIS-based maps, general adaptation zone maps were used: Typically, these maps were: Produced by a graphics artist working with an agronomist Based on broad groupings of climate and soils Not able to be combined with multiple sources of information Of minimal value for decision making 过去的方法 在使用计算机进行GIS测绘的方法出现以前，一般适应区地图被广泛采用。 这些地图的特点是： Historical approaches … • 由平面设计师和农学家合作完成 • 对气候和土壤只进行大致分类 • 无法整合多种信息资源 • 对决策支持的作用小 GIS and Spatial Analysis Approaches

  4. GIS manipulate and display layers of spatially variable data, including: geo-physical features (topography, soil traits, waters) climate spatial data (rainfall, temperature, radiation) biological characteristics (plant or animal tolerances) geo-political information (political boundaries, urban centers, transportation infrastructure). 新方法… GIS可以细致展现随空间变化的各项数据,包括: New approach … • 地理物理特性(地形，土壤特性，水文) • 气候空间数据(降雨，气温，辐射) • 生物特性(植物/动物 容限) • 地理行政信息(行政边界，城市中心，基础交通) GIS and Spatial Analysis Approaches

  10. Traditional approach has been qualitative New quantitative approach uses spatial data layers and integrates with crop tolerance values Tolerance values have been mapped Internet Map Server used for developing and mapping tolerances 量化研究方法和IMS Quantitative Approach and IMS • 传统方法是定性的 • 新的定量的方法使用空间数据层,并将农作物容限值融入其中 • 容限值也已被测绘 • 使用网络地图服务器来完善数据,测绘容限 Current quantitative, dynamic approach.
