油松飞播造林的地理分布和适宜性分区

根据我国北方地区历年油松飞播调查资料和对典型播区的调查 ,阐明了油松飞播的地理分布和效果 ;同时运用统计分析和模糊数学分析等方法 ,对影响油松飞播成效的主要因子作了系统的宏观分析 ,得出年均降水量和年均气温是影响飞播效果的主要因子。在此基础上 ,对北方地区油松飞播造林进行了适宜性分区 ,分区结果将油松飞播划分为 3个区 ,即造林适宜区 ,造林次适宜区和造林非适宜区 ,对指导今后油松飞播生产具有重要意义

According to the data of aerosowing chinese pine(Pinus tabulaeformis) over the years and the investigation of typical sowing areas in the northern region, the geographical distribution and results of aerosowing P.tabulaeformis are expounded; at the same time, the main factors influencing the results of aerosowing  P.tabulaeformis are studied and analysed macroscopically using the methods of statistical analysis and fuzzy mathematical analysis. The results of the study showed ...
