| Abstract: | Aim To discuss serveral basic academic issues on landscape scale. Methods Synthesis. Results Landscape scale curity. It will benefit to establish basic reference frame, to reveal scale change and assessment human factors and to direct regional regional ecological security and its assessment on is the right scale to assess regional ecological sespace-time dynamic characteristiss, to accomplish ecological restoration on landscape scale. Conclusion Assessment of regional ecological security on landscape scale will benefit to combine the present situation of regional ecological secruity with its dynamic appraisal, also benefit to dynamically assess and forecast the impact of human activity on ecological security. |
