The invention relates to a method and system for quantitative analysis of seabed stepped landform evolution. The method includes: obtaining the migration change data of the spatial position of the terrace edge points over time; according to the migration change data, establishing a first quantitative calculation model between the evolution process of the terrace terrain parameters and environmental factors; determining the first constant The parameters of the quantitative calculation model; according to the parameters and the first quantitative calculation model, obtain the second quantitative calculation model; according to the second quantitative calculation model, the environmental sensitivity factors and the environmental Analyze the contribution of sensitive factors. The invention can solve the problem that it is difficult to quantify the environmental sensitive factors in the formation process of the seabed stepped landform, and improve the accuracy of oceanographers in extracting and reconstructing key environmental information recorded by the stepped landform.
Description
technical field [0001] The invention relates to the field of marine geology and geophysics research, in particular to a method and system for quantitative analysis of seabed stepped landform evolution. Background technique [0002] Stepped geomorphic units are generally developed around islands and reefs and at the edge of continental shelf slope breaks. This unique geomorphic type not only records the temporal and spatial distribution of the "baseline" of sediment accumulation, but also becomes a key factor in the high-precision reconstruction of ancient sea levels, coastline changes, and island and reef ecology. It is an important analysis basis for status assessment, and it also records the submersion process of coral reefs. It is an important information window for basic scientific research on reef submersion mechanisms, climate evolution, and regional tectonic subsidence. Therefore, the study of reconstructing key marine environment evolution information by using the st...
