【摘要】：江西省赣州市是全国最大的柑橘生产地,为详细掌握柑橘果园的面积变化情况以及分析果园产量变化原因,以赣州市信丰县为研究对象,采用Landsat TM/OLI三期遥感影像,综合运用RS和GIS技术对2010—2016年柑橘果园面积变化进行遥感动态监测和分析。研究结果表明:2009年—2016年,信丰县柑橘果园经历了明显的土地利用动态变化,2009—2013年农田、林区、裸地主要转变成果园,2013—2016年则刚好相反;2009年至2016年柑橘果园种植面积呈先增加后减少的变化趋势,2009—2013年果园面积增长了近10.85 km2,2013—2016年果园面积减少了近30.49 km2;黄龙病,年平均气温及人均园地面积是影响柑橘果园面积变化的主要驱动力,其中2013年爆发的黄龙病对柑橘种植的影响尤为显著。研究结果与信丰同期统计年鉴中柑橘种植情况基本一致,能为柑橘果园产量变化做出合理分析,为中短期赣州柑橘产量预测提供科学依据。
[Abstract]:Ganzhou City, Jiangxi Province is the largest citrus production place in China. In order to understand the area change of citrus orchard and analyze the reason of orchard yield change in detail, taking Xinfeng County of Ganzhou City as the research object, the third period remote sensing image of Landsat TM/OLI is used. RS and GIS techniques were used to monitor and analyze the changes of citrus orchard area from 2010 to 2016. The results show that the citrus orchards in Xinfeng County experienced obvious land use dynamic changes from 2009 to 2016. From 2009 to 2016, the planting area of citrus orchard increased first and then decreased. In 2009-2013, the area of orchard increased by 10.85 km ~ 2 and decreased by 30.49 km ~ 2 in 2013-2016. The annual mean temperature and per capita garden area were the main driving forces affecting the change of citrus orchard area, and the outbreak of Huanglong disease in 2013 had a significant effect on citrus planting. The results of this study are basically consistent with those of Xinfeng statistical yearbook, which can provide a scientific basis for the prediction of citrus yield in Ganzhou in the short and medium term, and can provide a reasonable analysis for the change of citrus yield in citrus orchards.
