Study on Hydrochemical Characteristics and Interactions between Groundwater and Surface Water in the Dongting Lake Plain

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

The manuscript in its present form is not suitable for publication.

The title does not correspond to the overall topic because "transformative relationships" only appear in a small part at the end of the work. Moreover, this part is not even well explained, and it is not clear how the tracer concentrations were chosen for the calculation.

It is not clear what "hydroxide isotope technology" refers to, and the paper to which the authors refer is not in English. The same applies to the "hydroxide stable isotopes". I assume that these are stable isotopes of oxygen and hydrogen, but this is not clear from the text.

The description of the research area should also be clearer for international readers.  The map shown in Figure 1 needs to be explained in more detail. The international audience is not well acquainted with the current image description. 

The paper lacks a hydrogeologic map.

It is not clear according to which "technical specifications" the samples were taken. In general, the chapter on sampling should be more detailed.

The authors use incorrect abbreviations for conductivity and oxidation-reduction potential.

The equipment used is not specified according to the rules for writing a scientific article.

The formulations lack clarity and do not align with the expectations of a scientific article. For example, "the local evaporation line is lower than that...", "spatial trends are nearly the same", etc.

It is not clear what "project" in Table 1 refers to.

The "Data processing" section should be rewritten, as the software used was not cited appropriately and the description of certain statistical methods used is missing. Furthermore, inferential statistical methods are missing in the paper (specialy in the 4.1. section).

In section 4.3. it is not clear which correlation method was used (Spearman, Pearson?).

It is unacceptable to interpret the correlation as "obviously correlated".

Certain correlation coefficients may not be statistically significant, but they too have been interpreted!

Descriptive statistics for stable isotopes are missing. It would be desirable to have a table with these results.

Undefined abbreviations are used!

It is not clear where the data for LMWL comes from. It is strange that the precipitation is not collected in such a large study area and the LMWL comes from a different area. This area should be shown on the map so that the reader can get an idea of whether it is acceptable to use this LMWL at all.

The paper contains valuable information about the samples collected. But presented in this form, they are useless to the reader.

The manuscript still needs a lot of work to be acceptable for publication.

Comments on the Quality of English Language

Although the quality of the English language in the manuscript is not a significant problem, a revision is nevertheless necessary due to many typographical errors. E.g. "andecological", "this Paper", "50m", "aredeveloped", "recgahrgefrom" etc.

Such errors are not an obstacle to understanding but unnecessarily distract from the topic, tire the reader, and are not acceptable for publication.

Reviewer 2 Report

Comments and Suggestions for Authors

The paper about Study on Hydrochemical Characteristics and Transformation Relationships between Surface Water and Groundwater in the Dongting Lake Area is well structured and needs minor modification before being accepted for publication.

1. in the introduction part the authors must describe the novelty of their research connected to other research made in the same area

2. in the methodology part the authors can insert a flow chart to show the methdological stepts ued

3. in the discussion part the auhtors must describe the limitaiton of the methodology used compared with other researches

4. in figure 1 the elevation capture can be moved in the legend capture
