相思林

结果表明：气体污染物引起附近林地土壤pH值、有机质、全氮、碱解氮含量下降，台湾相思林在污染环境下改良土壤化学性质极为明显。

Results showed that the polluted air caused the nearby forest decline of soil acidification , the content of soil organic matter , the total N and available N. The Acacia confusa stand could improve the soil chemical characteristics evidently .

马占相思林径级大的树木个体数较少，但占据林段边材总面积和林段蒸腾的比例较大。

Even though there were less individual trees with large diameter at breast height ( DBH ) in the sample plot , they comprised relatively larger proportions of total sapwood area and transpiration of the forest .

以南澳岛台湾相思林不同生境梯度的种群作为一元资源位，共选取8个资源位进行调查，计测台湾相思林主要种群的生态位宽度、重叠和相似性比例。

Resources position by different habitat gradient populations were taken according to the investigation data of major forest group and plant multiplicity in Nan'ao Island . Total eight resource positions were selected to explore the niche breadth , overlap and proportional similarity of major population of Acacia confusa forest .
