Research advance in landscape pattern optimization

The theories and technologies for optimizing landscape pattern are the key issues in landscape ecology research, and increasing emphasis is on the issues especially as the turther studing of the relationships among landscape pattern, landscape function and landscape process. Landscape pattern optimization aims to build a kind of optimized landscape which could make landscape eco-efficiency maximized and ecological safety ensured, based on the understanding of the relationships among landscape pattern, landscape function and landscape process, and the proposing of optimal target and criteria. The researches mainly include the theories, technologies, and targets of landscape optimization and landscape management. This paper summarized the research advance on landscape pattern optimization at home and abroad, and some comments were put forward. Through analyzing some case studies, it was pointed out that landscape optimization research should integrate multiple methods, make quantitative study, and establish related evaluation standards.
