| 摘 要： | 通过林分调查和树干解析,应用灰色理论中的关联分析方法,对杨树防护林的生长量与气候因子之间的关系进行了定量分析,得出树高生长量与气候因子的关联序为:年日照时数>年最低气温>湿润度>年最高气温>年降水量>年平均气温>年相对湿度>年蒸发量;材积生长量与气候因子的关联序为:年日照时数>年最低气温>湿润度>年最高气温>年降水量>年相对湿度>年蒸发量>年平均气温。

| Abstract: | In the light of stand investigation and stem analysis, using relative theory of grey model, the relation between increment and climate factors was quantitively amalyzed. The result shows that the relative sequence is: annual sunshire hours>annual minimum temperatures>humidity>annual maximum termperatures>annual rainfall>annual mean temperatures>annual relative humidity>annual evaporation, and the ralative sequence between timber increment and climate factors is: annual sunshire hours>annual minimum temperatures >humidity>annual maximum temperatures>annual mean rainfall>annual relative humidity>annal evaporation>annual mean temperatures. |
