Dear Dr. Zhu,

Thank you for submitting your revised ms to BG

I had a quick look at your manuscript, and feel that the major concerns have been adequately addressed.

However, I would like to raise your concern about some minor points.

(1) The title can be rephrased as: Patterns of soil respiration and its temperature sensitivity in grassland ecosystems across China. As you can see, both reviewers, particularly reviewer#1 has major concern about the volume of your sample size. Although your reply appears reasonable, the key driver of soil respiration and its temperature sensitivity is not conclusively deciphered. I would like to say no single paper could resolve this problem, ant your attempt to tackle this question is welcomed. In addition, the need for more measurements might be highlighted at the text in the conclusion section.
(2) The advantage and disadvantage of ANOVA and paired t text need to be discussed for its ecological implication, rather than simply stating the methods used

Yours sincerely

Zhongjun
