摘要

To assess the value of air regulation in the Honghu Lake Wetland, a quantitative study was conducted based on existing literatures. Results showed that the total service value of air regulation in the Honghu Lake Wetland was 254.52 million yuan/a, which was 11.6 times of that by previous studies. The net value of fixed greenhouse gases via wetland plants (including carbon emission value from methane emission conversion into carbon dioxide greenhouse gas effect) was 58.50 million yuan/a, the data indicated that this lake wetland was a strong carbon sink. The value of oxygen released by the wetland ecosystem was 176.51 million yuan/a, and the value of regulating air humidity and temperature was 19.51 million yuan/a. The net value of greenhouse gases fixed by the Honghu Lake Wetland vegetation, the value of released oxygen, and the value of lifting air humidity and temperature regulation accounted for 22.98%, 69.35% , and 7.70% of the total value of the air regulation services, respectively.
