| 中文摘要: |
| 草原生态系统是我国面积最大的陆地生态系统,开展草原资源调查是掌握草原基本状况、制
定草原保护利用政策的最基础依据。根据第三次全国国土调查主要数据公报显示,全国草原面积为2.64 亿hm2,占国土面积的27.5%。系统梳理我国草原资源调查历程及分类体系演变,重点探讨了草原范围界定与分类方法等关键问题。结合水热条件与植被特征,对现有草原类区划体系进行
优化,提出6个类组,18个草原类的草原类区划体系。 |

| Grassland ecosystems represent the largest terrestrial ecosystem in China in terms of area.
Conducting grassland resource surveys serves as the fundamental basis for understanding the basic conditions
of grasslands and formulating policies for their protection and utilization. According to the main data
bulletin of the third national land survey, the total grassland area in China is 264 million hectares, accounting
for 27.5% of the country′s land area. This paper systematically reviewed the survey process and
evolution of the classification system of grassland resources in China, with a focus on key issues such as
the definition of grassland scope and classification methods. Based on hydrothermal conditions and vegetation
characteristics, the existing grassland classification system was optimized, proposing 6 categories
and 18 grassland types. |
