Abstract: In order to improve the calculation accuracy of landscape pattern gradient, the landscape pattern gradient of garden urban green space is studied under the guidance of ecology. Firstly, it expounds the important role of landscape pattern gradient research under the ecological guidance, as well as the connotation of garden urban green space landscape development under the ecological guidance. Secondly, the gradient characterisation parameters of landscape pattern are calculated, including green space landscape area percentage, number of regional patches, regional maximum patch index, landscape shape index, average patch area, aggregation index, patch density, separation degree, diversity index and evenness index. Finally, the horizontal and vertical coordinates of the grid are set, grid processing is carried out, and the gradient calculation of landscape pattern is completed. The experimental results show that this method can obtain accurate gradient characterisation parameters of landscape pattern, which is conducive to the development of landscape pattern.
