To this day , a lot of innovative researches focus on the production of the bamboos, the biological and abiological factors of restricting the bamboos' production, the nutrient cycle of the forest system, the relationship between the bamboos' clonal growth and regeneration of the system, the hypothesis for the bamboos' bloom mechanism etc. But the results were too confused, make the ecological process of the bamboo forest be unclear, and this is not enough to conserve panda and its habitat.

目前，各专家学者围绕大熊猫主食竹的生物量生产、制约大熊猫主食竹生物量生产的生物因素和非生物因素、大熊猫主食竹群落系统的养分循环、大熊猫主食竹种群的克隆生长与群落更新、大熊猫主食竹开花机理假说等方面作了大量的研究，但研究结果还具有许多不确定性，这对大熊猫主食竹群落系统生态学过程的深入了解还非常不够，同时也很难满足大熊猫及其栖息地保护的需要。

However, those decreased in secondary forest dominated by Alchornea trewioides, Mallotus conspuyrcatus, Eurycorymbus cavaleriei with lower species diversity. The SOM contents in rock-soil (110 g kg-1) and soil surface microhabitat (77 g kg-1) in gentle slope decreased significantly, which were only 32% and 35% of that in primary forest, respectively; but there were not significant differences in SOM, TN and AN contents in depression between the two vegetations.

Comprehensive analysis found that the bamboo played a more important role on improving the physical properties of the soil.And the second of that were mixed forest,pine forest and Amorpha fruticosa.

综合分析发现，竹林对土壤的物理性状改善比较大，其次是针阔混交林、马尾松林和紫穗槐。

Also all of them were better than bare land.The average soil water-holding capacity of different vegetation types was 157.69m~3/hm~2,which was 2.59 times of that of bare land(60.97m~3/hm~2).The descending rule of water-holding capacity was that:bamboo＞Tea＞Amorpha fruticosa＞Golden buckwheat＞Chestnut of return farmland＞mixed forest＞pine forest＞chinese chestnut Intercropping.

不同植被类型土壤平均持水能力为157.69m~3/hm~2，是裸地持水能力(60.97m~3/hm~2)的2.59倍；持水能力由大到小依次为竹林＞茶林＞紫穗槐＞金荞麦＞板栗退耕＞针阔混交林＞马尾松林＞板栗间种。

The pattern of vertical distribution of organic matter in mangrove soil reflected the roots distribution. Surface roots were abundant in Avicennia marina forest, so organic matter of soil in top layer (0-20cm) was the most there. However, the organic matter of soil in Kandelia candel forest was the most in middle layer (20-40cm) because roots were abundant in middle layer while there were fewer roots on surface soil. Content of organic matter in bottom layer (40-60cm) was generally lower in two mangrove forests.

1红树林土壤有机质的垂直分布模式反映了根系的分布状况，在地表根系发达的白骨壤林，表层土壤有机质含量高，而在地表少根而根系多集中分布于中层的秋茄林，中层有机质含量高，下层土壤有机质含量一般较低。
