基于遥感的富贵竹种植田时空格局变化

Spatiotemporal Pattern Change of Dracaena sanderiana Fields Based on Remote Sensing

以广东省台山市海宴镇为研究区,利用多期Landsat遥感数据对富贵竹种植田进行监测,研究富贵竹种植田的时空格局演变过程。结果表明:海宴镇富贵竹的种植面积先增多后减少,2010年总面积最大,为374.85 hm2;种植集约化趋势明显,种植田斑块数先增加后减少,最大斑块面积逐年增大。

Taking Haiyan town of Taishan city,Guangdong province as study area,multi-phase Landsat remote sensing data was used to monitor Dracaena sanderiana（DS） planting field,which was used to study temporal and spatial evolution process of DS plantation.Results showed that DS planting area increased first and then decreased,total area was the largest of 374.85 hm2 in 2010.Planting was being intensified,planted patch number increased first and then decreased,the largest patch area increased year by year.
