Method and system for acquiring site parameters of offshore wind plant

The invention provides a method and a system for acquiring site parameters of an offshore wind power plant, and the method comprises the steps: planning the distribution and number of fan positions of the whole wind power plant, and selecting representative sampling points through employing an optimization method; performing static pressure sampling on the representative sampling point to obtain a low-disturbance in-situ sample; static sounding testing is carried out on all the planned fan positions, and static sounding data of all the positions are obtained; testing the low-disturbance in-situ sample to obtain a soil body strength interpretation parameter of the representative sampling point; and by utilizing a Kriging method, expanding the interpretation parameters of the representative sampling points with a limited number to all fan positions so as to interpret the static sounding data. According to the method, the accuracy of site parameter prediction and evaluation can be effectively improved, the cost
