Reviewer 2 Report
1. Abstract
The objectives and conclusions of this paper should be limited to the regional scope of China
2. Keywords
Keywords should be distinguished from title
3. Introduction
Among the many factors affecting WUE and CUE, why only analyze the effects of CO2 and ND?
What were the innovative contributions and scientific assumptions of this paper?
Why was there no research on future climate change?
4. Data and methods
Does the delineation reflect the impact of nitrogen deposition and carbon dioxide on the Chinese scale? Its representativeness should be made clear.
5. Results and Discussion
The effect of CO2 and ND on the variation of regional LAI should be analyzed.
The differences between different regions should be illustrated with relevant datas.
