摘 要:
收集大量森林生态系统类型林冠截留功能研究资料,应用地统计学方法模拟了我国主要森林生态系统类型林冠截留的地理变化规律。结果表明：我国主要森林生态系统类型林冠截留与环境因素经度和纬度之间存在一定的地理变化规律,地统计学方法模拟的回归优度达88.15%,明显优于前人提出的三因素多元地理空间模型的模拟效果（回归优度为56.42%）,能更真实反映我国主要森林生态系统类型林冠截留的地理变化规律,从而为我国主要森林生态系统林冠截留时空分布的模拟与分析提供可靠方法。这些主要森林生态系统包括：寒温带、温带山地落叶针叶林;寒温带、温带山地常绿针叶林;亚热带、热带东部山地常绿针叶林;亚热带、热带西部山地常绿针叶林;亚热带西部高山常绿针叶林;温带山地落叶与常绿针叶林;温带、亚热带山地落叶阔叶林;亚热带山地常绿阔叶林;亚热带山地常绿落叶阔叶混交林;亚热带竹林;南亚热带山地季风常绿阔叶林;热带半落叶季风雨林;热带山地雨林。[著者文摘]

Abstract:
Based on the previous data from published papers concerning a variety of forests distributing in different graphical regions in China,the law of geographic variation of canopy rainfall interception of main forest ecosystems in China was studied by using geostatistics method in this paper.The results showed that there was an obvious law of geographic variation between canopy rainfall interception and longitude and latitude of environmental factors;that the regressing dominant degree of geostatistics method was 88.15% which was superior to the three-variable geographic space model（its regressing dominant degree was 56.24%）.The geostatistics method could better reflect the law of geographic variation of canopy rainfall interception of main forest ecosystems in China and could be a powerful tool for modeling and predicting the spatial distribution of canopy rainfall interception of main forest ecosystems in China.The main forest ecosystems in China included cold temperate and temperate mountains deciduous and conifer forest or ever-green conifer forest,subtropic and tropic eastern or western mountains ever-green conifer forest,subtropic mountains ever-green broadleaf forest or deciduous and broadleaf mixed forest,subtropic bamboo forest,etc.[著者文摘]
