浙江开化县“国家造林项目”立地质评价

Estimating Site Qualities for the“State Afforestation ltem”in Kaihua County,Zhejiang

用数量化理论(Ⅰ)模型,选取海拔、黑土层厚、坡位、波向、坡度、土壤厚度6个立地因子编制开化县杉木人工林数量化地位指数得分表,用预测模型预估开化县“国家造林项目”杉木造林小班的地位指数,进行立地质评价。

Numeral theoratic model (Ⅰ) was used to draw up a score table of site indexfor the artificial Chinese Fir forests in Kaihua County in which the six factors, i. e. elevation,depth of humus soil, slope level, slope direction, slope degree and depth of soil, were selectedas site factors. The site indexes of basic classes of afforested Chinese Fir forests were predictedby the calculation model, and from them the site qualities were estimated.
