Abstract

[Objective] The soil and water conservation effect mechanism of the two core elements (slope and vegetation) in a slope-to-terrace project were systematically analyzed to provide specific methods for multi-index mechanism research

to supplement and improve the ecological effect theory of water conservation projects

and to provide theoretical guidance for the practice of ecological civilization construction. [Methods] Slope and vegetation factors were comprehensively considered

and a variety of mathematical models were used to deeply analyze their water conservation effect mechanisms. [Results] ① Based on a linear model

the linear component decomposition of the total soil and water conservation effect of the five indicators in the full text under the same spatiotemporal conditions was realized. Furthermore

based on the precise calculation of the relative contribution rate of each component

the real source of the soil and water conservation effect of the slope-to-terrace project was revealed for the first time in a theoretical sense. ② Based on multiple regression analysis

the optimal mathematical model was selected from a large number of alternative models

and the specific influencing factors and mechanism of the soil and water conservation effect of the above components were profoundly revealed. ③ Based on structural equation modeling (SEM)

the rationality of the specific theoretical model including two latent variables (physical factor and chemical factor) reflecting the soil and water conservation effect of the five indicators in the full text was verified. By SEM group analysis

the preset models under the two slope conditions were fitted at the same time

clearly and intuitively showing the internal relationship between the factors and the differences in the mechanisms of the soil and water conservation effect under different slope conditions. ④ Based on principle component analysis

a comprehensive factor containing 80.8% of the information of five original variables was constructed

and the evaluation index was changed from five dimensions to one dimension

so as to realize the overall comprehensive quantitative evaluation of soil and water conservation effects. [Conclusion] Based on advanced data analysis methods

deep integration of research conclusions on the mechanism of the multi-factor soil and water conservation effect can be achieved

which deepens people’s understanding of its specific mechanism. It can also provide a methodological reference for the research of multi-index mechanisms

help to build professional mathematical models with higher predictive accuracy

and improve the efficiency of soil and water conservation practice.
