小叶(山东)林场于50年代营造大面积杉木纯林,成熟林单位面积蓄积量高低之间相差38倍,主要原固是造林时没有完全按照适地树的原则。对更新后的杉、松幼林设标准地调查,结果也表明不同立地的生长状况悬殊。山场优势植物种类及其生长状况可作为造林立地选择的主要依据,该场据此制订的“立地类型级及更新造林树种表”在应用中具有直观、准确、简便等优点。
Small leaf (Shandong) forest farm in the 1950s to create a large area of pure Chinese fir forest, mature forest unit area volume of 38 times the difference between the level of the main original solid is afforestation did not fully follow the principle of suitable trees. The updated survey of fir and pine and young forest was conducted on a standard basis and the results also showed that the growth of different sites was poor. The dominant plant species and their growth status in the mountainous area can be used as the main basis for the selection of planting sites. According to this site, the site type and the updated tree species list are intuitive, accurate and easy to use.
