Soil is an important parameter on water quality, and plays a key role in water quality evaluation, especially for inland water. Many remote-sensing methods have now been developed to reverse soil concentration. However, in natural water, the existence of chlorophyll-a affects the soil concentration reverse precision. In order to remove the effect of chlorophyll-a, an experiment is designed in this...
In this paper, based on the correlation analysis and by combining the principal component analysis, a correlation evaluation model-based principal component analysis is established. In the process of the water body evaluation eutrophication, a correlation analysis is conducted between the sample matrix and the standard matrix of the water body eutrophication evaluation. The sequence which has the...
Based on the analysis of the water quality monitoring data of Xingkai Lake in 2008, the eutrophic level of the water body was evaluated through a comprehensive trophic state index method. The results showed that the comprehensive trophic state index (CTSI) was 47.7 for Da Xingkai and 50.1 for Xiao Xingkai, which indicated that Da Xingkai is in a mesotrophic state and Xiao Xingkai in a light eutrophic...
