摘要
通过20世纪70～90年代30年气象资料统计分析,建立了天水半湿润山区适生林草区划数学模型;通过量化计算,得出了区内不同区域水、热匹配指标,并进行了适生林草配置的四级农业气候区划,为该区生态环境建设提供了科学依据.
Based on the analysis of meteorological data of 30 years from 1970 s to 1990 s,a mathematical model for suitable forest rough partition of half moist mountainous areas has been established. The different regional water and heat match indexes have been set up and 4 grade agricultural climate partitions have been made for suitable raw forests, thus providing a scientific basis for the construction of ecological environment in Tianshui.
