A stubborn problem for the designers of Bio2 was making rain for the cloud forest.

对生物圈二号的设计者们来说，一个难以解决的难题是为雾林造雨。

The preliminary results showed that the atmosphere contaminator mainly contained SO\-2, NO\-\%x\% and suspended granule. Which caused large area acid rain with high frequency. As pollution became more serious, there were decreases in pH value and increases in the content of SO\+\{2-\}\-4 and Al\+\{3+\} in forest soil; the chlorophyll concentration also would decrease...

初步结果表明：大气污染引起珠江三角洲地区发生大面积、高频率的酸雨，主要的污染物有SO2 、NOx、悬浮颗粒物等；随着污染程度的增大，森林土壤pH值降低，SO2 - 4和Al3+质量浓度增大；马尾松、湿地松叶片叶绿素含量降低，生长衰退甚至死亡；但不同树种对大气污染敏感程度不同，种植马占相思比马尾松更能增加林地对酸雨缓冲力和提高土壤肥力。

When big, moderate rain and rainstorm, the Y value size order is always the masson pine pinus elliottii mixed forest＜the wetland pinery＜the wetland pinery＜the locust tree forest＜the locust tree pinus elliottii mixed forest＜the thin forest, to the soil protection effect, the conifer forest is better than broad leaved forest. For annual rainfall erosion, the Y value ordered: Locust tree forest＜wetland pinery＜locust tree pinus elliottii mixed forest＜wetland pinery＜masson pine pinus elliottii mixed forest＜thin forest.

大、中雨和暴雨时，Y值的大小顺序都是马尾松湿地松混交林＜湿地松林＜湿地松林＜刺槐林＜刺槐湿地松混交林＜疏林，对土壤保护效果针叶林优于阔叶林；对于年降雨侵蚀，Y值的大小顺序是：刺槐林＜湿地松林＜刺槐湿地松混交林＜湿地松林＜马尾松湿地松混交林＜疏林。

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。
