| 摘 要： | 东南湿润区是我国生态环境问题最为突出的区域之一,水体的富营养化是困扰该区域经济和社会发展的主要问题。尤其近些年来,在政府鼓励和市场推动双重作用下,丘陵山区的开发力度逐步加强,越来越多的原生态竹林被开发为经济型用地(如茶园)。但该土地利用方式的转变在带来经济效益的同时,也改变了下垫面土壤孔隙结构和土壤水文过程,从而极大地影响着营养盐随土壤水分的迁移和转化。在国家自然科学基金青年科学基金项目“太湖流域丘陵区坡面土壤水文过程物理机制及模拟研究”的资助下,在以下3个方面取得了重要进展：①不同土地利用坡面土壤水分时空变化与影响因素;②坡面水文过程与水量平衡;③坡面土壤水文过程影响机制。目前对太湖流域丘陵区土壤水文过程研究虽取得一些进展,但其影响机制仍不十分明确,有待进一步深入的探讨。上述成果的取得以及未来的持续探索,对于太湖水体富营养化与流域面源农业面源污染控制具有重要的环境意义,进而为推动我国流域生态文明建设提供理论支持。 |

| Abstract: | The humid region of Southeast China is one of the most prominent areas of environmental problems. Eutrophication of water bodies is a major problem that hampers the economic and social developments in the region. Especially in recent years, affected by government policies and market forces, the development of hilly and mountainous areas was intensified. Increasingly more virgin bamboo forests have been developed into economic land (such as tea garden). However, the land-use and land-cover change brings economic benefits as well as changes of soil pore structure and hydrological processes, which greatly affect the migration and transformation of nutrients in the soil. Within the National Natural Science Foundation of China (NSFC) supported project “Research on the physical mechanism and numerical simulation of hillslope soil hydrological processes in the hilly region of the Taihu Lake Basin” we made important progresses in the following three aspects: (1) spatiotemporal variations and influencing factors of hillslope soil moisture under different land use; (2) hillslope hydrological processes and water balance; and (3) influencing mechanism of hillslope soil hydrological processes. Despite these progresses, further research should focus on mechanisms of such processes, which would be of great importance for the control of eutrophication of the Taihu lake and non-point source pollution. |
