研究了杉木迹地和非迹地重新造林后一些树种生长结果的情况和土壤养分与酶活性的变化。结果表明，杉木迹地土壤有机质、全氮和水解氮平均分别下降了35.59%，55.55%和33.94%；脲酶和蛋白酶分别平均下降43.06%和22.63%。杉木迹地上林木早期生长受到一定的影响，特别是速生树种。但利用杉木迹地时采取深翻改土和施基肥加强土壤管理等措施，青梅、板栗和银杏早期产量分别达到24.5 t*hm－2，1.2 t*hm－2和0.3 t*hm－2，同样能取得早果丰产。表5参6

Effects of soil on growth and fruiting of trees and biochemical characteristics of the soil were studied by planting non-timber species on both Chinese-fir-clear-cutting land and non-Chinese-fir-clear-cutting land．It's shown that organic matter，total nitrogen，hydrolysable nitrogen，available phosphate and contents of urease，proteinase，hydrogen peroxidase，etc．decreased to different extents，thus soil fortility declining．As a result，early growth of trees was suppressed to some extent，which was particularly obvious in such fast growing species as Vatica astrotricha and Phyllostachys pubescens．When Chinese-fir-clear-cutting land was reutilized，measures such as deep scarification and improvement of soil and application of basal manure were taken，with early fruiting，high yield and good quality obtained in Vatica astrotricha，Castanea mollissima，Ginkgo biloba，etc．Thus the sustainable utilization of Chinese-fir-clear-cutting land could be realized．
