| 摘 要： | 景观格局与生态过程的耦合研究是景观生态学研究的核心科学问题,也是综合自然地理学深化和发展的关键.尺度广泛存在于生态学现象中,尺度效应与尺度转换是景观生态学研究面临的挑战,探讨格局与过程之间相互作用机理与尺度特征是为解决尺度问题提供理论依据的必然途径.水土流失作为一种生态过程,是国内外颇为关注的生态问题.依据多种研究手段,在不同尺度上开展景观格局与水土流失的相互关系与尺度特征的研究,在分析景观格局的时空异质性、水土流失的影响因子与尺度效应的基础上,揭示流域景观格局与水土流失的耦合机理,发展尺度转换方法和景观格局-水土流失过程耦合模型,是完善景观生态学的理论基础,是为水土流失区生态建设提供科学依据的重要途径.

| Abstract: | Coupled research between landscape pattern and ecological processes is a key topic of landscape ecology,as well as a point for deepening of comprehensive physical geography. Scale effects and scaling are challenges for ecologists. Dealing with the scale issues should follow the deep understanding of interaction michanism and scale characteristic between pattern and processes. As one of ecological processes,soil and water loss has been paid much attention. Controling soil and water loss needs a solid scienti... |
