景观格局优化研究进展

随着景观格局、功能和过程研究的深入,格局优化作为景观生态学新的研究领域被提出,但其理论和方法的研究仍然是景观生态学研究的一个难点问题.本文通过分析国内外的学者的研究工作和发表论文,对景观格局优化重要问题进行了总结.景观格局优化是对景观格局、功能和过程综合理解的基础上,通过建立优化目标和标准,对各种景观类型在空间和数量上进行优化设计,使其产生最大景观生态效益（生态、经济和社会效益）和实现生态安全.研究的主要内容包括：景观格局优化的理论和方法研究,优化标准的研究和景观管理的研究.通过案例分析可以发现,多种研究手段的结合、定量化研究和景观格局优化评价标准将是格局优化实现的研究方向.

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.
