The invention belongs to the field of marine sediment geochemistry and marine geology research, and particularly relates to a method for evaluating multiphase methane release flux in the forming process of a cold spring chimney body. A cold spring carbonate rock chimney body is taken as a research object, and the method comprises the following steps: firstly, carrying out mineralogy, geochemistry and geochronology analysis on a chimney body sample, and qualitatively recovering the formation process of the chimney body; secondly, establishing a three-dimensional chimney body forming model based on a three-dimensional cylindrical'reaction-diffusion 'model, and quantitatively calculating the release flux of multiphase methane (including a dissolved state and a bubble state) in chimney body forming; the method constructed by the invention is helpful for further researching important scientific problems of influence of cold spring methane release on ocean, biology and atmospheric environment and the like, so that the understanding of carbon exchange between sediment lithosphere and ocean water circle is improved, and the method has important scientific significance for further understanding geological, environmental and biological co-evolution of the cold spring area.

The application relates to the technical field of water conservancy and environmental geology, and particularly discloses a measuring device for cracks in water conservancy and environmental geology, which comprises a support, a plurality of sliding blocks connected to the support in a sliding mode, an extender arranged on the sliding blocks, an installation plate fixedly connected to the extensible end of the extender, and a flexible plug rod assembly arranged on the lower side of the installation plate and capable of being inserted into cracks in the water conservancy and environmental geology layer. The measuring device for cracks in water conservancy and environmental geology provided by the application injects silica gel solution into the cracks, forms crack filling models after the silica gel solution is solidified, takes out the crack filling models from the cracks, measures the sizes of the crack filling models, and thus realizes the measurement of the cracks, so that the crack size measurement is more intuitive and accurate.
