摘要
土地利用/覆被变化能直接反映当今全球环境变化的主导因子———人类活动,为此土地利用/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意义和实践价值。针对土地利用/覆被变化引起的环境效应的复杂性、累积性,本文在总结国内外LUCC环境效应的研究成果的同时,把LUCC环境效应分为:土壤环境效应、大气环境效应、水环境效应以及生态效应四类进行阐述,并结合目前研究在内容和方法方面存在缺乏统一的指标体系、研究区域时空尺度单一、以单要素静态研究为主、实验研究相对薄弱以及动态模拟不够等问题对其发展趋势进行了探讨。
As Landuse/cover change（LUCC） directly reveals human activity, the predominant factor which has brought global environmental change, file environmntal effects brought by LUCC are Lcing paid morn attention. It is very important both to theories and practices to study the environmental effects of land use/cover change. Although it is not easy to analyze thoroughly the complex environmental effects of LUCC, the environmental effects were classified in this paper. LUCC not only affected soil environmental,elimate environmental and water environmental but also brings ecological effects which is emphasized in this paper. Also, the insufficiency of study such as the lack of united indicator system for estimation, poor precision of experiments, single factor and single process static studies and the development of correlation study in the future is discussed.
