The regional pattern for ecological security (RPES): designing principles and method

The newly proposed concept, the Regional Pattern for Ecological Security (RPES), provided an integrated strategy for implementing ecosystem restoration and biodiversity conservation at regional scale. Based on the concept and its theoretical basis, the designing principles and a preliminary method were put forward. The principles were determined mainly based on that of the Landscape Ecological Planning after some necessary supplementation in regard to the emerging properties of the new concept. The regional pattern design for ecological security integrated the relevant two kinds of ecological planning approaches, the Pattern Optimization and the Disturbance Management according to the features of regional ecological and environmental problems and human disturbances. Some other methods, like GIS, Spatial Simulation and the Scenarios Study, were also integrated into the planning. The designing highlighted the pertinent, regional, systematic, and active characteristics of the RPES concept, and supplied a new technical support to the Adaptive Ecosystem Management and the realization of ecological security in region.
