Abstract: Because the traditional method does not consider the accurate evaluation of the environmental conditions of the garden space, the restoration method of the garden space environment has the problems of low evaluation accuracy and high restoration cost. Therefore, a garden space environment restoration method based on P-IBI factor analysis is proposed. The P-IBI index is calculated to determine the environmental restoration index, and the factor scoring result is obtained by combining common factors, and common factors according to the evaluation index standard, so as to realise the P-IBI factor load analysis. Based on this, the garden space environment restoration plan is determined. The experimental results show that the evaluation accuracy of this method is always above 94%, the average evaluation time is 0.74 s, and the maximum restoration cost of the garden space environment is 549,000 yuan. It can be seen that this method has a certain practical application effect.
