Almost all the vegetation types occurred in a small study area, so the present study was typical and representative. The results show that the corrosional ratios of different vegetation types at different elevations are quite different. In general, the corrosional ratios increase gradually from the forest land of Shuifang spring, through the bamboo forest land of Shuifang, the meadow of Shuifang and the forest of Bitan spring, to the shrub of Bitan spring.

结果表明：在整个降雨季内5种灌木林林冠平均截留率从大到小依次为榛子灌丛24.86%、接骨木灌丛21.24%、珍珠梅灌丛19.10%、胡枝子灌丛11.99%和绣线菊灌丛7.70%。5种灌木林分中，枯落物最大持水率均为自身重量的2～3倍，最大持水量变化幅度为20.90～33.48 t/hm~2。

Some shrub species have low water utilization efficiency such as Rungia Chinensis, Buckthorn, Cotinus coggygria, Kirilow indigo and so on.

灌木树种中，阳性的蒸腾速率高于阴性树种；平均水分利用率是阴性灌木大于阳性灌木树种。

A spring-flowering shrub or small tree of the genus Crataegus.

山楂属的一种春季开花的灌木或小乔木。

Species richness and Pielou evenness index were used to measure species diversity. Species richness in polluted area was 32-67, while in control area it was 47-82. Pielou evenness index of tree layer was 0.1161-0.8509, while those of shrub layer and herb layer were 0.1763-0.3249 and 0.0443-0.2601, respectively. The results showed that both species richness and Pielou evenness index were influenced by the point source pollution. Species importance values showed significant differences between polluted area and control area. Dominance of different species had changed, and some species even disappeared under the pressure of pollution, indicating a process of species replacement in plant communities. Such species replacement can provide a scientific basis for species selection for restoration of human-damaged ecosystem. The natural regeneration of Quercus variabilis was insensitive to pollution, while Cupressus funebris was effected seriously.

仅在污染区中出现的物种数量远低于仅在对照区中出现的物种数量；(2)可分出4种基本的群落类型：马尾松林、柏木林、栓皮栎林和马尾松＋栓皮栎林，各群落特定层次的物种丰富度指数以及Pielou均匀度指数在污染区与对照区之间存在显著差异；(3)污染胁迫下，物种在群落中的生态优势度发生了变化，反映了群落中不同物种相互替代的过程，这种物种的替代可为今后受损生态系统人为恢复过程中物种的筛选提供一定的理论参考；(4)对群落中王要物种更新的调查发现：栓皮栎林对污染不敏感；柏木林污染区与对照区幼苗数量及分布格局均有明显差异，污染条件下群落未来演替受到严重干扰。

The canopy interception will increase with the precipitation during at the beginning of rain, but it will keep stable later. The canopy interception quantity of six forest types is Mixed conifer forest, Pinus massoniana forest, Cupressus funebris forest, Conifer and broadleaf forest, Broadleaf forest and Shrubbery and grass land in order.There is much difference among the different species of the shrub and herbage.

林下灌草层不同的物种最大持水量有很大区别，在测定的物种中持水量最大的是糯米条，持水量最小的是柞木，糯米条的持水量接近柞木的3倍。6种森林类型林下灌草生物量从大到小依次是灌草地、马尾松林、针叶混交林、针阔混交林、阔叶林和柏木林；灌草层的持水量与其生物量具有密切关系，生物量多的持水量相应也多。

In habitats of the broad-leaved forest, the dominant tree are the species of Fagaceae in tree layer, Theaceae, Saxifragaceae and Lauraceae in shrub layer, Cyperaceae, Dryopteris spp. and Liliaceae in herb layer.

在阔叶林型栖息地中，乔木层主要树种为壳斗科植物，灌木层植物以山茶科、虎耳草科和樟科等科的种类为主，草本层植物以莎草科、蕨类和百合科为主。
