| 摘 要： | 通过对杉木火力楠混交林乔木叶、灌木、草本、凋落物的生物量和持水性能及土壤容重、有效水等的测定,结合当地降雨情况,推算出林地地上部分各层次的持水量和持水深及地下部分0—40cm土壤有效贮水量,结果表明,杉木火力楠混交林地上部分持水量及年持水深均最高;0—40cm土壤有效贮水量每公顷比杉木纯林多143.39m~3。

| Abstract: | Based on the situation of the local precipitation, the water reserves, the water-reserve depth of different layers above the forest floor and effective water reserves in soil of 0-40 cm depth underground were infered by defermining the biomass about tree leaves, shrubs, herbs and debris as well as hydrologic factors and soil water reserves on weight. The results showed that the soils in different layers of the forest floor in mixed stand ( Cunninghamia lanceolata , Michelia mac-clurei)had the highest water content and in the soils of 0-40 cm depth effective water content per ha. increased 143.39m3 over that in pure stand. |
