A Quantitative Research on the Site Quality of Pinus massoniana Plantation in Zhejiang Province

  • Received Date: 1994-05-30
  • According to the data of eight site factors and nine interaction factors of 290 investigation plots of Pinus massoniana plantation in Zhejiang, the regression with interaction factors and quantitative theory Ⅰ were used in the calculation(the uneffective variables were picked off).The site factors, such as:altitude,thickness of soil and fertility of the first layer,slope position,orientation of slope etc.of north slope of Wu Yi Shan Mountain, Tian Mu Shan Mountain, Eastern and Western hill area of Zhejiang were analyzed by statistics.The statistics test on distrepance standard deviation, variance ratio,mnultiole correlation and partial correlation shows:the result of quatitative method is the most precise one.

Abstract: According to the data of eight site factors and nine interaction factors of 290 investigation plots of Pinus massoniana plantation in Zhejiang, the regression with interaction factors and quantitative theory Ⅰ were used in the calculation(the uneffective variables were picked off).The site factors, such as:altitude,thickness of soil and fertility of the first layer,slope position,orientation of slope etc.of north slope of Wu Yi Shan Mountain, Tian Mu Shan Mountain, Eastern and Western hill area of Zhejiang were analyzed by statistics.The statistics test on distrepance standard deviation, variance ratio,mnultiole correlation and partial correlation shows:the result of quatitative method is the most precise one.
