As an important wet tree species in the construction of wetland ecosystem, Taxodium hybrid ‘zhongshanshan’ has been widely planted in the lakeside of Dianchi Lake. It is an important link in the water governance of Dianchi Lake. This article uses the average biomass method to catch Laoyuhe river wetland zhongshan carbon ability to analyze and estimate the value of carbon sequestration oxygen release zhongshanshan’s carbon capacity and build growth model. There was no significant difference of zhongshan sequoias carbon ability. The carbon sequestration capacity of zhongshanshan decreased. The carbon storage of ‘zhongshanshan’ in Laoyuhe wetland and Dianchi Lake is 2439 t and 122400 t, respectively. The value is 5.83 million yuan and 293 million yuan respectively. In 2017, the contribution rate of carbon sequestration and oxygen release value in the growing season was 19.5%.
In order to explore the spatial distribution characteristics of nutrients in the dianchi Lakeside and its influence on the eutrophication of dianchi Lake water, 21 sampling points were set up in the dianchi Lakeside to investigate the water quality, and the water samples of Dianchi Lake were collected, analyzed and measured TN, TP, CODCr, Chla and SS. The results showed that the spatial distribution of TN, TP, CODCr, Chla and SS concentrations in the lakeside of Dianchi differed. The spatial distribution of chlorophyll a showed a trend of high in the north and low in the south, and high in the west and low in the east. Chla was highly significantly correlated with TN in the northern and eastern water bodies in the lakeside of Dianchi, and TN had strong variability. In the south and west, TN is significantly correlated with CODCr and TP, while in the south, chlorophyll a and nutrients have less spatial variability and the risk of pollution is relatively small. The scientific sub-regional pollution prevention and control plan for the lakeside of Dianchi is of great significance for the water quality restoration of the lakeside.
