景观格局与土壤养分流动

Landscape Pattern and Soil Nutrient Flux

不同尺度上景观格局与生态过程的关系是景观生态学的研究重点。根据 Habit-Food- Resource范式 ,研究土壤养分流动与景观格局之间关系可为认识不同尺度上景观格局与生态过程的关系提供帮助。土壤侵蚀是山区和丘陵地区影响景观格局和土壤养分流动的重要过程之一。景观格局间土壤养分动态变化还没有引起足够的重视。采用 SCS范式 ,评价了黄土高原地区景观格局与土壤养分流动的关系。

Studies on the relationship between landscape patterns and ecological process at different scales are the focal point of landscape ecology. According to Habit-Food-Resource paradigm, soil nutrients flux passing through landscape is an important process influencing landscape patterns. Soil erosion is an important process affecting landscape patterns and soil nutrients flux in hilly areas. And studies on the dynamics of nutrients flux with soil erosion through landscape have not given more attentions. Through adopting the integration of scale down and scale up or SCS paradigms, the relationship between landscape pattern and soil nutrient flux in Chinese loess plateau was evaluated.
