Major Land Uses

ERS has been a source of major land use estimates in the United States for over 50 years, and the related U.S. cropland used for crops series dates back to 1910. The Major Land Uses (MLU) series is the longest running, most comprehensive accounting of all major uses of public and private land in the United States. The series was started in 1945, and has since been published about every 5 years, coinciding with the Census of Agriculture. See the latest report in the series, Major Uses of Land in the United States, 2007.

Data from all 14 Major Land Uses reports have been combined into a set of files showing major land use estimates by region and State from 1945 to 2007. Alaska and Hawaii were added in 1959, when they achieved Statehood. Since Alaska contains such vast acreage, 50-State totals in all categories prior to 1959 may appear to change precipitously.This record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog.

美国土地资源统计局（ERS）作为美国主要土地利用估算数据的主要来源，已逾半个世纪。与之相关的美国农作物用地系列数据可追溯至1910年。主要土地利用（MLU）系列是对美国公共和私人土地所有主要用途进行最长期、最全面的统计记录。该系列始于1945年，此后大约每五年发布一次，与农业普查同期进行。请参阅该系列最新报告《美国土地利用主要用途》，发布于2007年。该系列中所有14个主要土地利用报告的数据已合并成一套文件，展示了从1945年至2007年各区域及各州的主要土地利用估算。阿拉斯加和夏威夷于1959年加入州籍时被纳入，鉴于阿拉斯加面积之广，1959年之前的所有类别50个州的累计数据可能显得波动较大。本记录源自美国农业部企业数据目录，并输入至https://data.gov目录。本记录的数据资源包括以下内容：包含链接至Excel文件的网页。如需完整信息，请访问https://data.gov。
