Outline
Based on the data of pH and environmental parameters from 2011 to 2017, using the method of grid statistics and time-space matrix, contrastive analysis of pH in each environmental unit and the correlation of pH and environmental factors were studied. Furthermore, the differences of relevant factors affecting different seasons, regions and water levels were analyzed. The results showed that: (1) during from 2011 to 2017, the spatial distribution of pH was relatively stable in the Bohai Sea, the average value of surface pH in environmental units was from 7.95 to 8.38, the bottom was from 7.89 to 8.35, the absolute variation of average value was 1−1.5 standard deviations; (2) the time series of pH in each environmental unit tend to change synchronously, but there were differences among the units due to the different spatial distribution, the distribution characteristic of surface pH in winter was consistent with the saline; (3) there was a significant positive correlation between pH and chlorophyll a content in the Bohai Sea, and the surface pH varied seasonally, which was obviously consistent with distribution and variation characteristics of chlorophyll a, therefore, biological factor played an important role in regulating the pH of surface water; (4) the low value region of pH in Bohai Sea bottom in August was consistent with the formation of hypoxic zones by regional water stratification, and it was found that the bottom pH was positively correlated with dissolved oxygen; (5) the characteristic information of acidification indicators was further displayed by gridding processing technology and time-space matrix analysis method, which provided a good technical support for long-time scale analysis and research under climate change.
