摘要
草地资源是畜牧业生产的物质基础和生物多样性的基因库,具有防风固沙、涵养水源的生态功能,草地资源调查及监测意义重大。基于卫星遥感的草地分类不仅能够为草地资源调查提供数据支持,也可为草地物种多样性研究提供依据。基于野外调查数据获取真实样地草地类型信息,利用辐射定标、大气校正、图像融合等预处理后的Landsat8遥感影像,通过目视解译遥感判读的方式,使用ArcGIS软件构建了塔城地区8类草地类型共3360张多光谱遥感图像分类训练数据集。本数据集可为塔城地区草地类型遥感图像分类研究提供数据基础,同时可为其他地区相关领域的科研人员提供数据参考。
Grassland resources are the material basis of animal husbandry production and the gene pool of biodiversity,which have the ecological functions of preventing wind,fixing sand and conserving water.Grassland classification based on satellite remote sensing can not only provide data support for the investigation of grassland resources,but also provide a basis for the study of grassland species diversity.Based on the field survey data,the grassland classification information of real sample plots was obtained.Based on field survey data,the grassland type information of real sample plots is obtained.Landsat8 remote sensing images that have been preprocessed by radiation calibration,atmospheric correction,image fusion,seamless mosaic,etc.are used.After the operation process of dataset sample labeling,sample data clipping,result inspection,data enhancement,etc.,combined with visual interpretation of remote sensing interpretation,ArcGIS software is used to construct 8 types of grassland in Tarbagatay Prefecture,a total of 3360 multispectral remote sensing image classification training datasets,and the number of sample images in each category is between 300-580.This data set can not only provide data basis for remote sensing image classification of grassland in Tarbagatay Prefecture,but also provide data reference for researchers in related fields in other areas.
