景观生态学原理在土壤学中的应用

从研究的背景、本质及内容来看 ,现代土壤学有着鲜明的景观生态学内涵 ,研究离不开景观生态学观点的指导。土壤研究的尺度、土壤性质的时空异质性及过程的动态性决定着在大尺度上土壤学研究必须采用景观生态学的观点 ,这也是土壤学发展的一个必然趋势。土壤学汇集了众多学科的前沿研究方法 ,而景观生态学在理论上为土壤学研究拓展了更大的空间。作为学科交叉及研究动态 ,文章给出了景观生态学和土壤学研究相关联的许多热点研究动态 ,同时讨论了土地利用、土壤侵蚀、土壤面源污染等研究的景观生态学本质 ,从理论与实践上指出了景观生态学原理对土壤学研究的意义。

Application of Landscape Ecology Principle in Soil Science

Modern soil science possesses the clear landscape ecology features because of its research background, attribute and practice. Therefore the studies on soil science need the guidance of landscape ecology. For the reasons of soil research scales, the spatial and temporal variability of soil prosperities and the dynamics of soil process, the landscape ecology principles should be applied to the large-scale soil research and the combination of them is a trend of soil science. Soil research scope will be further expanded by the applications of landscape ecology theories besides many others science progresses. By the presentation of some research trends related with landscape ecology and soil science and the landscape ecology nature of soil research such as land use, soil erosion, soil non-point source pollution, the paper gives the theoretical and practical significance of landscape ecology principles application in the soil science.
