Abstract:

Ecological red line is a new eco-environment protection planning system in China. The concept of the ecological red line originated in the last decade and has developed into a national strategy. The purpose of ecological red line delineation is to ensure ecological integrity and ecosystem service function,and make sure that the economy develops in a sustained way. Red line areas of ecology play an important role in ecological security and environmental protection in China. Ecological red line delineation remains at an early stage,so here we review the definition and historical evolution of the ecological red line. The theories of ecological red line are summarized,including ecological security,ecological carrying capacity,ecological integrity and ecosystem service function. Indexes for evaluating ecosystem service function and eco-environmental sensitivity are summarized. According to different natural environment characteristics and ecosystem types,we propose key evaluation content and indexes for ecological red line planning in different regions of China,and analyze key issues in the progress of ecological red line delineation such as the minimum area percentage of ecological red line for local ecosystems;ecosystem function and ecological sensitivity evaluation content selection;minimum evaluation unit selection;ecosystem function and eco-environmental sensitivity evaluation methods and power determining;spatial data resolution selection and processing;coordinating ecological red line with other city planning;and how to manage the ecological red line. Preliminary advice for these issues are discussed. We hope this study supports ecological red line delineation theoretical development.

Key words: ecological red line, environment protection, ecological security
