收藏资源简介:
SPAM (Spatial Production Allocation Model) 是一个全球作物生产分配模型数据库,提供2000年至2020年间42种作物的种植面积、收获面积、产量等空间分辨率为8.6公里的数据。该数据库采用交叉熵方法将国家和省级数据细化为网格单元,揭示作物生产系统的空间模式,旨在帮助政策制定者和捐助者更好地制定农业和农村发展政策,提高粮食安全并减少环境影响。
SPAM (Spatial Production Allocation Model) is a global crop production allocation model database that provides data on planted area, harvested area and yield for 42 crop types at a spatial resolution of 8.6 km between 2000 and 2020. This database uses the cross-entropy method to disaggregate national and provincial-level data into grid cells, revealing the spatial patterns of crop production systems. It aims to assist policymakers and donors to better formulate agricultural and rural development policies, improve food security and reduce environmental impacts.
