【摘要】 本研究根据垂直分布对伏牛山南坡全部109种常绿阔叶木本植物野生环境的降水量进行了研究。结果表明,伏牛山南坡常绿阔叶木本植物垂直分布与降水量存在明显的关系,其有90种的年降水量在1000mm以上,海拔在700～1800m之间;101种的年降水量在900mm以上,海拔在500～2100m之间;79种的4～10月降水量在900mm以上,海拔在700～1700m之间;103种的4～10月降水量在800mm以上,海拔在500～1900m之间;79种的1～3月降水量在100mm以上,海拔在0～400m之间。该区最大年降水量为1072.29mm,位于1200m附近,降水量指标为北亚热带;4～10月最大降水量为1001.30mm,位于1200m附近;1～3月最小降水量为56.07mm,位于1000m附近,降水量指标为寒温带。建议将北亚热带的边界定位伏牛山南坡海拔1000～1200m之间。同时建议北方地区及城市参照伏牛山南坡常绿阔叶木本植物的适应降水量进行引种驯化。更多还原

【Abstract】 According to the vertical distribution of broad-leaved evergreen woody plants in Funiu Mountain,the precipitations in wild environment are studied.The result shows that there is clear relationship between the vertical distribution and the precipitation and there are 90 species whose precipitation per year is above 1000mm.whose altitude is between 700～1800m;there are 101 species whose precipitation is above 900mm.whose altitude is between500～2100m;there are 79 species whose precipitation between April and October is above 900mm,whose altitude is between700～1700m;there are 103 species whose precipitation between April and October is above 800mm,whose altitude is between 500～2100m;there are 79 species whose precipitation between January and March is above 100mm.whose altitude is between0～400m.The highest precipitation is 1072.29mm.where the altitude is about 1200mm whose precipitation is belong the that of north boundary of subtropical zone;the highest precipitation between April and October is 1001.30.mm,where the altitude is about 1200mm;the lowest precipitation between January and March is56.07,where the altitude is about 1000mm whose precipitation is near that of cold-warm.zone,we suggest that the north boundary of subtropical zone should be between 1000～1200m and the introduction domestication of the Broadleaved Evergreen woody Plants in Funiu Mountain should carried out.according to the precipitation factors.更多还原
