Spatiotemporal Pattern Change of Dracaena sanderiana Fields Based on Remote Sensing

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.
