摘要:

本文以目前国内外普遍关注的全球变化(Globe Change)为背景,利用地理信息系统(GIS)为技术手段,从林冠截留、枯落物蓄水、林地土壤拦蓄这三个森林水文生态功能最主要的层次出发,模拟分析了气候变化前后我国森林降水截留功能地理分布规律的差异。2030年中国气候变化的未来情景依据7个GCM大气环流模型的预测结果,选用树冠降水截留模型和森林综合截留模型,在IDRISI地理信息系统的支持下模拟气候变化对我国森林降水截留规律的可能影响。

Abstract:

Proceeding from the most important spatial layers in forest-hydrology ecological function, i. e. forest canopy, forest litter and forest soil, the potential impacts of climate change on geographical patterns of forest rainfall interception were simulated by means of GIS. The future climatic change scenario of China in 2030 was projected according to the seven GCMs. The canopy rainfall interception model and integrated rainfall interception model of forest ecosystems were established to predict the likely changes in forest rainfall interception in response to future climate change by using the IDRISI - GIS.
