中文摘要 | 草地退化作为生态环境恶化的重要因素越来越引起人们的重视。在进行那曲地区草地退化评价中,应用遥感技术取得较好的结果。在调查中应用草地退化重要因子草地盖度与遥感图像植被指数之间较好的相关关系,利用野外调查测得的草地盖度样方资料,与在遥感图像上测出的各样方的植被指数的相关关系,进行监督分类,依据退化草地评价指标体系,对那曲地区草地进行科学评价并编制退化草地图。通过调查和测算,那曲地区草地退化面积占草地面积(不包括难利用草地)的48.8%。 |
英文摘要 | Grassland degradation is a key factor of eco-environmental deterioration and more and more attention is paid to grassland degradation. As we know, there are wide land and few people in Tibet. The athor applied RS technology to the grassland degradation assessment in Naqu area and got a good result. The good correlativity between grassland coverage got in field study and NDVI calculated with RS images was used in the supervised classification. Finally we assessed the situation of grassland degradat ion according to its ssessment index system, and drew the map of grassland degradation as well. Studied results showed that the grassland degradation is very serious, and the grassland degradation area in Naqu area is 13650900hm^2 which accounts for 48.8% of the grassland area in Naqu. The light degradation area accounts for 59.3% , the middle one 29.2%, and the serious one 11.5%. |
