| 摘 要： | 在全国范围内采用MODIS EVI植被指数结合多源环境因子数据的方法实现对主要草地类型的划分.在借鉴第一次草地调查分类方案的基础上,提出了新的草地分类方案,将我国的天然草地划分为9类.根据气候带分布状况划分我国的四大草地资源分区,在分区内进行草地分类.在分类中通过量化分析各草地类型增强型植被指教和高程、降水、积温和湿润...

| Abstract: | The main grassland types in China were classified by using the integrating method with MODIS EVI and multi-source data of environmental factors in this study.Based on the classification system of the first national grassland survey,this study established a new grassland classification system,in which the natural grassland types in China were classified into 9 types.The distribution areas of grassland in China were divided into four grassland regions by climatic distribution zones,and the grassland types wer... |
