| 摘 要： | 通过计算广西区域多时相MODIS-NDVI值,结合GPS选定甘蔗样本训练区多时相NDVI值变化曲线,以及甘蔗生长周期长达8个月至1年以上,蔗糖生产期间甘蔗面积逐渐递减的特性,采用最大似然法提取非样本训练区甘蔗种植信息,最终实现广西区域的甘蔗种植空间分布遥感信息的提取。经对遥感影像图甘蔗连片种植区域、零散点种植区与GPS实地定位调查比较,结果表明广西区域甘蔗种植信息遥感监测与实况相符。在此基础上,对广西区域甘蔗种植面积估算面积进行初步统计,精度达到90%以上。 |

| Abstract: | An automatic approach was presented to extract the sugar-cane planting area for the mixed vegetation and hilly region in Guangxi province by using the moderate spatial and high temporal resolution MODIS data. The samples of a training region were selected by GPS and the temporal variation curve of NDVI was worked out. The maximum likelihood method was used to extract the information of sugar-cane planting area and its spatial distribution through calculating the multiple phase MODIS-NDVI. The comparison of results from remote sensing images with the investigations by GPS shows that the sugar-cane planting area can be extracted from MODIS data, and the accuracy is more than 90%. |
