摘要: 土地利用/覆被变化产生的环境问题已引起人类社会的广泛关注,深入研究这些问题具有重要的理论和实践意义。在简要回顾土地利用/覆被变化对大气环境、土壤环境和水环境影响已有研究的基础上,结合中国研究的实际,分析了中国土地利用/覆被变化的环境效应研究中存在的问题,并对今后的研究趋势做了讨论。

Abstract: It is very important both to theories and practices to study the environmental effects of land use/cover change, which has been paying more and more attentions by human. About the impacts of land use/cover change on atmosphere, soil, water and biodiversity, progresses are reviewed and inadequacies in past studies are also discussed. In the past time, lack of united indicator system for estimate, poor precision of experiments , single factor or single process static studies are main problems of researches on the environmental effects of land use/cover change. Based on them, this paper presents some contents, especially soil and water environmental effects should be further studied, such as processes and mechanism, different temporal and spatial scale and so on. Furthermore, it is pointed out that dynamic methodology should be used to conduct integrated impacts assessment of land use/cover change on environments. To evaluating those effects, it is necessary to develop a physically-based distributed model, which should integrate remote sensing and geographical information systems with mechanism of hydrological cycle and soil erosion models. Moreover, interdisciplinary cooperation and exchanges should be enhanced in order to improve the understanding of the land use and land cover change dynamics and their relationships with the environmental change.
