Farms with Significant Degradation Problems (Soil Acidity), 1998-1999

\r\n\r\nThis data relates to the proportion of farms who experienced significant soil\r\nacidity problems in the period 1998-1999. Proportion of farms with significant\r\nsoil acidity is reported at the Statistical Division (SD) level for Australia.\r\nThis data relates to broadacre and dairy farms run by owner managers. The data\r\nwas collected by Resource Management Supplementary (RMS) survey interview\r\nwhich accompanied the ABARE Annual farm survey in 1998-1999.The data is\r\npresented at a scale of 25000000. Projection -P Albers Equal-Area Conic -D\r\nWGS84 -m 132 -o 0 -p -18 -p -36 -e 0 -n 0The following attributes are\r\ncontained within the dataset; Sd_code a a unique 3 digit code for Statistical\r\nDivisions (SD), Sd_name a the name of the Statistical Division (SD),Soil_acid\r\na the proportion of farmers who experienced problems in 1998-1999.RSE a the\r\nrelative standard error for the period 1998-1999.Note that metropolitan areas\r\nare assigned a value of -99999, whilst areas with no data are assigned a value\r\nof -88888.\r\n\r\nSee [further metadata](http://data.daff.gov.au/anrdl/metadata_files/pa_fdpsar9aa\r\n__01811a00.xml) for more detail.\r\n\r\n

本数据集涉及1998-1999年间遭遇严重土壤酸化问题的农场占比。澳大利亚各统计分区（Statistical Division, SD）层面均报告了存在严重土壤酸化问题的农场占比。本数据集涉及由业主经营的广域农田与奶牛场。数据通过1998-1999年伴随ABARE年度农场调查开展的资源管理补充调查（Resource Management Supplementary, RMS）访谈收集。数据以1:25000000的比例尺呈现。投影方式：Albers等积圆锥投影（Albers Equal-Area Conic），基准面WGS84，参数-m 132、-o 0、-p -18、-p -36、-e 0、-n 0。数据集包含以下属性：Sd_code（统计分区（SD）的唯一3位编码）、Sd_name（统计分区（SD）的名称）、Soil_acid（1998-1999年间遭遇问题的农场占比）、RSE（1998-1999年间的相对标准误差（relative standard error））。请注意，都市区赋值为-99999，无数据区域赋值为-88888。更多详情请参见[进一步元数据](http://data.daff.gov.au/anrdl/metadata_files/pa_fdpsar9aa__01811a00.xml)。
