基于GIS和耕地质量评价划定基本农田--以江西省余江县为例
Delimitation for prime farmland based on GIS and farmland quality evaluation results---a case study of Yu Jiang County in Jiangxi Province
摘要
Abstract
Using delimitating of the prime farmland based on the GIS spatial analysis technology and the farmland land quality evaluation results in the YuJiang County,Jiang Xi Province. On the Arcgis platform,farmland plots were chose as the evaluation unit,two evaluation factors included the farmland natural conditions and the farmland quality classification and grading results. Twelve indicators were slope,irrigation condition,drainage condition,soil type,organic matter content, effective phosphorus,rapidly-available potassium content,soil pH,soil erosion, farmland national natural grade,farmland national economical grade and farmland national utility grade. Based on these factors and indicators ,this paper established the prime farmland delimitation model emphasis on the farmland quality. The evaluation results showed that the areas of the farmland evaluation scores which were higher than 85 were 28 775.32 hectares, these farmlands were delimitated into the prime farmland protection area and the prime farmland protection ratio was 80.06%.The GIS and the farmland quality evaluation results could provide scientific basis for the delimitating of the prime farmland.关键词
