Research method for soil water replenishment and earth surface vegetation conditions through phreatic water evaporation and application

The invention discloses a research method for soil water replenishment and earth surface vegetation conditions through phreatic water evaporation and application of the research method in research of ecological restoration of semi-arid grassland strip mine areas. According to the method, a certain amount of hydrogen and oxygen isotope tracing liquid is injected into the to-be-measured buried depth soil layer to simulate the to-be-measured buried depth phreatic water surface, so that the problems that in an existing field test, phreatic water levels with different buried depths are blindly found, a large number of drill holes need to be drilled, the workload is huge, the field phreatic water depth is fixed, and the testing efficiency is high are solved. The problem that target burial depth diving is not easy to carry out due to the fact that artificial change is difficult is solved, test research is greatly facilitated, the test cost is saved, the hydrogen and oxygen isotope tracing liquid is injected into a b
