丘间低地生态过程研究进展

丘间低地是《国际保护日程》所列的重点保护生境,近50年来一直受到生态恢复和生物多样性保护专家的关注.本文从丘间低地植被过程、土壤发育过程、水文过程、尺度对丘间低地生态过程的影响,以及丘间低地生物多样性保护及生态恢复等方面概述了丘间低地生态过程的主要研究内容、趋势和进展.近十几年,丘间低地生态过程研究体现了从单尺度到多尺度或跨尺度、从表征描述到机制探讨、从野外调查到控制试验过渡的趋势.然而,丘间低地生态过程的尺度性仍有待进一步探讨,丘间低地景观格局对生态过程的影响尚不清楚.今后,半干旱内陆地区丘间低地生态过程的研究将趋于增多,干扰生态学和景观生态学的理论和方法将会在丘间低地研究中得到更多应用.

Research progress in ecological processes in dune slacks

As a key protected habitat type in the International Conservation Agenda, dune slack has received much attention in recent 50 years. From the aspects of vegetation processes, soil processes, hydrological processes, effects of scale on ecological processes, as well as biodiversity conservation and ecological restoration, this paper reviewed the main research contents and progress in ecological processes in dune slakes. In recent decades, the related researches are being undergone the shifts from single scale to multi-scale or cross-scale. To elucidate the mechanisms of different ecological processes, the transition from observational study to manipulation experiment has also become one of the characteristics. However, the effects of scale on ecological processes in dune slacks should be further approached, and the influences of dune slack landscape pattern on ecological processes should be better understood. For the future, the studies on the ecological processes in dune slacks in semi-arid region would be in progress, and the theories and methodologies of disturbance ecology and landscape ecology would be applied extensively.
