Method for monitoring stony desertification evolution process of dolostone karst region

The invention provides a method for monitoring the stony desertification evolution process of a dolostone karst region, and the method comprises the following steps: automatically recording the relative water level of a flow cross section of a research area through a water level automatic recorder, and deducing and obtaining flow data through the Chezy formula and the Manning formula in hydraulics and hydrology; measuring the concentrations of Ca2+ and Mg2+ through outdoor onsite titration and a VBTAMPX type lab inductive coupling plasma light emission spectrometer; calculating the chemical denudation rate of a dolostone drainage basin according to the obtained data, the known relative density of dolostone and the catchment area of the drainage basin; carrying out the year-by-year comparison according to the calculated chemical denudation rate of the dolostone drainage basin, and judging the stony desertification evolution trend of the dolostone karst region. According to the invention, the method can achieve
