福建省土地利用/覆被变化对区域生态环境影响研究

土地利用/覆被变化对区域生态环境的影响已成为国际土地科学研究中最为活跃的前沿领域之一,也是相关领域研究的重点。从气候、生物多样性、土地退化等几个方面分析了福建省土地利用/覆被变化对陆域生态环境的影响,土地利用变化对湿地的影响。结果表明:土地利用通过改变土地覆被将从正反两面影响区域的生物多样性;土地利用/覆被变化主要通过改变地表反射率和大气中气体含量影响气候质量;不同的土地利用类型和土地覆被程度引起土壤侵蚀的程度不同,土壤侵蚀过程加速了土壤养分的流失与土壤退化。

Effects of Land Use/Land Cover Changes on Regional Ecological Environment of Fujian Province

The influence of land use/land cover change on ecosystems is one of the most active frontiers of land science research in the world. This paper examines the influence of land use and land cover change on a regional ecosystem, with a focus on aspects including biodiversity, climate and land degradation. The results indicate that land use affects biodiversity in Fujian Province both positively and negatively due to different types of change in land coverage. Land use affects the climate, mainly by changing the land surface albedo and atmospheric composition. Different types of land use lead to different degrees of soil erosion and soil nutrient loss. The paper also considers the effects of land use on wetlands.
