Gallery delimiting method in township-level territorial space planning

The invention relates to the technical field of corridor delimitation, and relates to a corridor delimitation method in township-level territorial space planning, which comprises the following steps: 1) source and ground identification: selecting three indexes of a maximum plaque area index LPI, a shape index SHAPE and a proximity index PROX, and constructing a source and ground connection degree measurement and evaluation index system; 2) corridor identification: constructing a comprehensive resistance surface according to land cover types, gradients, roads and water networks which influence energy flow of different space substances, and materializing space hindrance encountered in the circulation process; the intensity of interaction between the galleries is measured and calculated by using a gravity model so as to express the importance degree and the effectiveness of each gallery, and the galleries which play an important role in the connectivity of each space in the research area are extracted.
