琅琊山不同植被枯落物下土壤性状调查与分析

以琅琊山植物志为参考，选取11个典型的琅琊山植被类型，并采集土壤样本。利用野外采样与室内测试分析相结合的方法，对琅琊山不同植被类型下土壤的理化性质进行了分析。结果表明：（1）不同植被类型下土壤物理性质差异较大，从土壤含水量看，含水量最大的是水杉，最小的是接骨木；从土壤容重看，容重最大的是接骨木，最小的是麻栎。（2）从土壤化学性质看，pH值最大是石蒜，最小的是早竹；有机质含量最高的是金线松，最少的是麻栎。

Analysis on the Properties of Soil under Different Vegetation Types in the Langya Mountain

Based on the flora of Langya mountain for reference,selected eleven typical Langya mountain veg-etation type,and collected soil samples. By using the method of field sampling and indoor test analysis, physicochemical properties of soil in different vegetation types in Langya mountain was analyzed. The re-sults show that：（1）The difference of soil physical properties under different types of vegetation is larger, from the content of soil moisture,the soil moisture of metasequoia is the maximal and the elderberry is the minimum;from the soil bulk density,the soil bulk density of elderberry is the maximal,and the german oak is the minimum. （2）From the chemical properties of soil,the pH of lycoris radiata is the maximal and the phyllostachys praecox is the minimum;the organic matter of Ulmus chenmoui is the maximal and the german oak is the minimum.
