Landscape pattern optimization for Xianghe Segment of China’s Grand Canal

ABSTRACT

Optimization of landscape patterns in urbanizing areas is important for landscape planning, thus improving regional ecological security and human sense of beauty to environment. In this study, we integrated a variety of methods to optimize landscape patterns in Xianghe Segment of China’s Grand Canal (XSCGC) based on the principles of landsenses ecology. The plan scheme consisted of a spatial configuration of key ecological elements, called one point, one axis, two cores, multicorridors, and multidemonstrations. The ecological corridor system was arranged in the plan area to reverse ecological barrier effects induced by urban infrastructure and to improve connections between landscape units. The plan area was divided into 11 ecological function zones for management, protection, and development purposes. Seven ecological control indices were proposed corresponding to an ecological core and ecological developing areas to ensure ecological security. This landscape pattern optimization scheme will help achieve harmonious development of the socio-economic and eco-environment for the plan area in the future.
