2014年“一带一路”陆域草地NPP总量为7.77亿tC/a，区域差异显著。由于水热充足，东南亚区草地面积小，但生产力最高，年NPP约为310gC/a·m2，远高于全区平（61.92gC/a·m2）。由于气候寒冷，俄罗斯北部苔原年NPP小于10gC/a·m2。亚欧草原普遍光照充足，气候干旱，年NPP为10～50gC/a·m2。青藏高原地区年平均气温一般在0℃以下，草地类型以高寒草甸与高寒草原为主，草地NPP以10～50gC/a·m2的分布为主。

In 2014, the total terrestrial grassland net primary productivity (NPP) of the Belt and Road Initiative (BRI) region reached 777 million tC/a, with significant regional disparities. Benefiting from sufficient water and heat resources, the Southeast Asian sub-region has a small grassland area but the highest productivity, with an annual NPP of approximately 310 gC/(a·m²), far exceeding the regional average of 61.92 gC/(a·m²). The northern tundra of Russia exhibits an annual NPP of less than 10 gC/(a·m²) due to its frigid climate. The Eurasian steppes generally feature ample sunlight and arid climates, with annual NPP ranging from 10 to 50 gC/(a·m²). On the Qinghai-Tibet Plateau, where the annual average temperature is typically below 0°C, the dominant grassland types are alpine meadows and alpine steppes, and grassland NPP is predominantly distributed within the range of 10 to 50 gC/(a·m²).
